Victron energy ORI121236140 Orion-Tr Smart DC-DC Charger Non-Isolated

Charger

 General Description

The Orion-Tr Smart DC-DC Charger can be used as a power supply or as a battery charger. In charger mode, the three-state charge algorithm will increase battery life by properly charging the battery. Especially in the case of vehicles with a smart alternator, or voltage drop caused by long cable runs, controlled charging is indispensable. Controlled charging will also protect the alternator in lithium systems where direct charging can overload the alternator due to the low impedance of the lithium battery. In fixed output mode the output voltage will remain stable independent of the applied load or varying input voltage (within the specified range).
The Orion-Tr Smart DC-DC Charger can be set up to only provide power when the engine is running. This is possible thanks to the built-in engine shutdown detection. This also prevents the onboard voltage of the vehicle from becoming too low. It is not necessary to intervene in the system of the vehicle, to install a separate motor run sensor, or to intervene in the CAN-bus system. Apart from this detection, the Orion-Tr Smart DC-DC Charger Isolated can also be activated by a forced allowed to charge feature, e.g. connected to the ignition switch. The Orion-Tr Smart DC-DC Charger is fully programmable with the VictronConnect App. Discover all setup possibilities in the VictronConnect manual.

 Features

Smart alternator compatibility
Vehicle manufacturers are now introducing smart ECU (Engine Control Unit) controlled alternators to increase fuel efficiency and reduce emissions. Smart alternators deliver a variable output voltage and are shut down when they’re not needed. The converter has an engine running detection mechanism. This prevents the converter from discharging the starter battery when the alternator does not supply power. See section 5 of this manual for more details.

Separation of the starter battery and the service battery
The Orion-Tr Smart DC-DC Charger Non-Isolated separates the starter battery from the service battery when the engine is not running.

Extensive electronic protection
Over-temperature protection and power derating when the temperature is high.

•  Overload protected.
•  Short circuit protected.
•  Connector over-temperature protection.

Adaptive three-step charging
The Orion-Tr Smart DC-DC Charger Non-Isolated is configured for a three-step charging process:
Bulk – Absorption – Float.

Bulk
During this stage, the controller delivers as much charge current as possible to rapidly recharge the batteries.

Absorption
When the battery voltage reaches the absorption voltage setting, the controller switches to constant voltage mode. For lead acid batteries it is important that during shallow discharges the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge, the absorption time is automatically increased to make sure that the battery is completely recharged. For lithium batteries absorption time is fixed, default 2 hours. The fixed or adaptive mode can be chosen on the battery settings.

Float
During this stage, float voltage is applied to the battery to maintain it in a fully charged state. When the battery voltage drops substantially below this level, due to a high load for example, during at least 1 minute, a new charge cycle will be triggered.

Flexible charge algorithm
Programmable charge algorithm, and eight preprogrammed battery settings. Configurable with VictronConnect.

Adaptive absorption time
Automatically calculates the proper absorption time. Configurable with VictronConnect.

Configuring and monitoring
Bluetooth Smart built-in: the wireless solution to set up, monitor and update the controller using Apple and Android smartphones, tablets or other devices. Several parameters can be customized with the VictronConnect App.
The VictronConnect App can be downloaded from: https://www.victronenergy.com /support-and-downloads/software Use the VictronConnect manual – to get the most out of the VictronConnect App when it’s connected to an Orion Smart.

Input voltage lock-out
Shutdown if the input voltage drops below the lock-out value and restarts when the input voltage increases above the restart value. Configurable with VictronConnect.

Remote on-off
Use the remote function to enable and disable the converter remotely with the remote on/off a connector or using the VictronConnect App. Typical use cases include a user-operated hard wired switch and automatic control by for example a Battery Management System.

Figure 2: Typical connection set up  as a charger

Connection remote on-off
The recommended use of the remote on-off is:

•  A switch wired between the L-H pins (On-level impedance between L-H pins: < 500kΩ)
•  A switch wired between (input/starter) battery plus and H-pin (on level: > 3V)
•  A switch between the L-pin and (input/starter) ground (on level: < 5V)
•  BMS control through the H-pin

Voltage tolerance L & H pin: +/- 70VDC

Engine shutdown detection override
In charger mode, the “engine shutdown detection sequence” determines if conditions are met to enable charging, see chapter 5. The “engine shutdown detection override” forces the charger to allow charging independently of the engine shutdown detection. Engine shutdown detection override is activated by applying >7V to the remote L-pin. This allows external control (e.g. ignition switch, CAN bus engine on the detector) to enable charging.

This function does not override the remote on-off function. Remote connection a), b) or d), as shown in Figure 3 must be configured in combination with engine shutdown detection override. See examples in figure 4.

Enable charging with an ignition switch and remote on-off option a)

Figure 4: Engine shutdown detection override connection diagram.

If the ignition switch in figure 4 is switched off, the charger will return to “engine shutdown detection” mode, it will not turn off the charger.

To force enable/disable charging (i.e turn the ORION on/off) without the “engine shutdown detection” a remote option as given in chapter 4.4 must be wired, and the engine shutdown detection must be switched off in VictronConnect, see figure 5.

Figure 5: Disable engine shutdown detection

When the engine shutdown detection has been switched off in Victron Connect (‘forced charging’) current will be drawn from the starter battery even if the engine is not running.

During ‘forced charging’ the input voltage lockout is the only limit left to disable charging automatically, make sure this level is not set too low, in most applications 12.5V is sufficiently low.

Engine shutdown detection

The engine shutdown detection mechanism simplifies your ORION-Tr DC-DC Charger system by detecting if the engine is running without wiring additional switches or sensors. The factory default setting will work with most regular and smart alternators but can be re-configured with the VictronConnect App.
Configuring the engine shutdown detection depends on the voltage generated by the alternator when the engine is running. Regular alternators will generate a fixed voltage (e.g. 14V) whereas smar alternators generate a variable output voltage that can range from 12.5V to 15V. Especially smart alternators in a regenerative braking system show large alternator voltage variations. Engine shutdown detection is only active in charger mode. The feature can be disabled by the “engine shutdown detection override” and in VictronConnect as shown in figure 5. In power supply mode the “input voltage lock-out” determines when the output is active.

The engine shutdown detection is updated from software version v1.05 onwards.

Engine shutdown detection sequence

Figure 8: Engine shutdown detection sequence

• 0 → 1: If the engine runs the alternator voltage will ramp up, when Vstarter > Vstart, charging is enabled.
• 1 → 2: The input current produces a voltage across the input cable (Viable); this voltage reduces the voltage measured by the charger (VIN). If VIN > Vshutdown the charger will operate at Imax.
• 2 → 3: If VIN ≤ Vshutdown, the charge current will be reduced to prevent VIN to drop below Vshutdown.
• 3 → 4: If VIN < Vshutdown for longer than 1min (shutdown) “engine off” is detected and charging is disabled. If VIN > Vshutdown before shutdown runs out, charging remains enabled.
• 4 → 5: If Vstart(delay) < VIN < Vstart charging is enabled after tstart delay (configurable).

Engine shutdown detection setup with VictronConnect

Open VictronConnect and press the Cog symbol to enter the settings.

Figure 9: Engine shutdown detection setup menu
The following settings can be changed with VictronConnect:

The default values displayed are for the 12V input models. Those values are scaled depending on the input voltage of the model. E.g. for 24V input models, the default values displayed on the manual should be multiplied by 2.

Engine shutdown detection enabled:
The engine shutdown detection is always enabled by default when the charger mode is selected. When it is disabled by the user or when the power supply mode is selected, the engine is considered to be running, so no shutdown detection will take place.

Alternator type: The alternator type can be selected between “Smart Alternator”, “Regular Alternator” and “User-defined”. When the “Smart Alternator” option is selected, the default values for the smart alternator are/will be applied to the engine shutdown detection settings. The same will happen when the “Regular Alternator” option is selected. When any of the settings differ from the default values of the last two options, the “User- defined” option will be selected. Default: “Smart Alternator”.

Start voltage (Start):
At this level, charging starts immediately. Default: 14V.

Delayed start voltage (Vstart(delay)):
Smart alternators can generate a lower voltage when the engine is running, therefore a lower start level is necessary for these systems. To ensure that the starter battery is recharged after starting the engine, charging of the auxiliary battery is delayed during this condition. The energy used during starting must be replenished to ensure that the starter battery remains properly charged. Default: 13.3V (Smart Alternator) and 13.8 (Regular Alternator).

Delayed start voltage delay (start delay):
Recharge time for the starter battery during start level (delayed). Example: If the starter draws 150A for 5sec to start the engine, about ~0.2Ah is drawn from the starter battery. If during engine idling, the alternator can only generate 20A, it takes 150A/20A x 5sec =37.5sec to recharge the starter battery. Default: 2 minutes.

Shutdown voltage (Vshutdown):
This level corresponds with the engine being off. This keeps the starter battery fully charged and provides a hysteresis with respect to the start level. The hysteresis must be large enough to prevent VIN to drop to Vshutdown which would result in charge current reduction. Action will be taken after shutdown runs out (1 minute); this allows charging during temporary low voltage conditions. Default: 13.1V (Smart Alternator) and 13.5V (Regular Alternator).
The range for engine start/shutdown levels:

•  12|12; 12|24: 8 to 17V
•  24|12; 24|24: 16 to 35V

Setup input voltage lock-out:
Input voltage lock-out is the minimum level at which charging is allowed, below this level charging stops immediately. Default (in charger mode): lock- out: 12.5V / restart: 12.8V. Default (in power supply mode): lock-out: 10.5V /restart: 12V.

When ‘forced charging’ is enabled, the current will be drawn from the starter battery if the engine is not running. Setting the lock-out level very low can result in a depleted starter battery.

To setup input voltage lock-out two criteria are important:

• Minimum alternator voltage: A smart alternator can operate at very low alternator voltage (<12.5V) e.g. when the vehicle accelerates. This low voltage is allowed during the shutdown as shown in “engine shutdown detection sequence 3→4”. If charging must remain enabled during this period, the lock-out level must at least be set below the minimum alternator voltage.

If the low voltage period exceeds shutdown charging will be disabled on engine shutdown detection.

The voltage drop across the input cable:
As seen in “engine shutdown detection sequence 1→3”, VIN will be lowered by Viable. When the alternator voltage drops fast (smart alternator) the charge- control needs some time to reduce charge current and keep VIN at Vshutdown. During this time Viable must not trip the voltage lock-out. Therefore, the lock-out value should be: Vlock-out ≤ Vshutdown – Viable.

Example: Calculate the input cable voltage drop:

•  Distance between starter battery and charger: 5m.
•  Vshutdown= 13.1V. Recommended wire gauge: 16mm2.
•  Cable resistance: ~1.1mΩ/m @20°C, thus Rcable = 1.1mΩ x 10m (2x 5m) = 11mΩ.
•  A 12|12-30A Smart Charger will draw about 35A from the input when running at full capacity, resulting in:
•  Vcable = 11mΩ x 35A = 385mV.
•  Vlock-out ≤ Vshutdown – Vcable = 13.3V – 385mV ≈ 12.9V.

Cable connections, external fuses, temperature, etc. influences the total cable resistance.

 VictronConnect – Orion Smart DC-DC Charger

Introduction
Thank you for using VictronConnect. This guide will help you get the most out of your Orion Smart DC-DC Charger and it requires minimum knowledge of this charger that can be found in the introduction. The information available here applies to all Orion Smart DC-DC Chargers. To simplify the reference to the Orion Smart DC-DC Charger, it will be referred as just Orion Smart in this guide.
More general information about the VictonConnect App – how to install it; how to pair it with your device; and how to update firmware, for example – can be found by referring to the overall VictronConnect manual.
Note: Where input and battery voltage is referred to in these instructions, a 12V input and battery is assumed. Please multiply the given values by 2 to arrive at settings for an installation configured for 24V.

•  Float: During this stage, the float voltage is applied to the battery to maintain a fully-charged state. When the battery voltage drops below Re-bulk voltage for at least 1 minute, a new charge cycle will be triggered.
•  Input Voltage shows the voltage measured on the input terminals of the device.
•  Output voltage shows the voltage measured on the output terminals of the device.
•  When the Orion Smart is on Off state, it will not measure the output voltage, so this value will appear as ‘—’

Settings
VictronConnect allows the user to change and adjust several different settings from the Orion Smart. This is done through the settings option that can be accessed by clicking the icon on the right top corner of the screen. The settings options are different according to the operation mode that is selected.

Charger Mode
When on Charger Mode, these are the available settings.

•  The function allows choosing between “Charger” or “Power supply”. When charger mode is selected, the Orion Smart will follow the three-state charge algorithm. For more information about the charge algorithm, please read the Orion Smart manual.
• Battery settings allow changing the battery settings in order to adjust the absorption voltage, float voltage, and others to fit the battery being charged. The battery setting is explained better on the next item.
• Input voltage lock-out allows choosing between two thresholds. One to set the lock-out and another one to reset it. Normally, a minimum 0.5V (for 12V input Orion Smart) difference is used for better performance. The protection can still be disabled if desired by the user. For more information about the input voltage lock-out, please read the Orion Smart manual.
• Engine shutdown detection allows choosing between two thresholds. One to set the detect the engine shut down and another one to detect when it is running. Normally, a minimum 0.2V (for 12V input Orion Smart) difference is used for better performance. The engine shutdown detection can still be disabled if desired by the user. For more information about engine shutdown detection, please read the Orion Smart manual.

Charger Mode – Battery Settings

• Charger enabled
  • Toggling this setting turns the Orion Smart off. The batteries will not be charged.

• Charger settings – Battery preset
  • Battery preset allows to select the battery type; accept factory defaults; or enter your own preset values to be used for the battery charge algorithm. The Absorption voltage, Float voltage, Bulk time limit, Re-bulk voltage offset, Adaptive absorption time and Absorption time, settings are all configured to a preset value – but can be user-defined.
  • User-defined presets can be stored in the preset library – in this way installers will not have to define all the values each time they are configuring a new installation.
  • By selecting Edit Presets, custom parameters can be set as follows:

• Absorption voltage
  • Set the absorption voltage

• Float voltage
  • Set the float voltage

• Bulk time limit
  • Set the maximum bulk time allowed for the charger.

• Re-bulk offset voltage
  • The re-bulk offset voltage determines what is the offset between the float voltage (or absorption if it is lower) and the re-bulk voltage. The re-bulk voltage is the battery voltage threshold that triggers another charge cycle. For example, when the charger cannot maintain the battery voltage due to a high load, the battery voltage will fall and a new charge cycle will be started once the battery voltage drops below the re-bulk voltage.

• Absorption time
  • The absorption time depends on if the Adaptive absorption time algorithm will be used or not. If that setting is not set, the charger will use a Fixed absorption time, selected by the user. Now, if the adaptive absorption time is set, then the charger will determine the absorption time based on the bulk elapsed time of that charge cycle, the Maximum absorption time in this case is also set by the user.

Power Supply Mode

When on Power Supply Mode, these are the available settings.

•  The function allows choosing between “Charger” or “Power supply”. When power supply mode is selected, the Orion Smart will keep the output voltage asset on the setting.
•  Output voltage allows choosing the output voltage when the power supply mode is selected. Note that the minimum and maximum voltages need to be within the product limit (i.e.: 10V to 15V for 12V output Orion Smart)
•  Input voltage lock-out allows choosing between two thresholds. One to set the lock-out and another one to reset it. Normally, a minimum 0.5V (for 12V input Orion Smart) difference is used for better performance. The protection can still be disabled if desired by the user. For more information about the input voltage lock-out, please read the Orion Smart manual.
