Tools

  • Insulated tools must be used
  • Voltmeter
  • Post cleaner and wire brush
  • Personal protective equipment

Battery Location
Locate the batteries close to the power conversion device in order to minimize the length of the battery cables. Care should be taken to ensure adequate clearance above the batteries is maintained for access to both battery and power conversion device connections and disconnects.

Protection from exposure to water, including water sprayed from nozzles, should be ensured.

AES Battery performance and service life will be optimized when they are operated in an ambient temperature of 15°C to 25°C (59°F to 77°F). Care should be taken to ensure that the battery’s temperature is > 0°C (32°F) during charging.

Securing Battery

  • Battery can be strapped in place with non-conductive nylon straps
  • Battery may have hold down brackets at the base of the battery

Installation
Battery cables must be sized to the specifications required by the inverter charger, and must be installed in accordance with the standards set by the authority having local jurisdiction. Do not use or install a battery temperature sensor.

  • Confirm that battery is set to OFF
  • If the battery circuit has a disconnect – open the disconnect to isolate battery
  • Cable connection points should always be kept clean
  • Broken, frayed, brittle, kinked or cut cables should never be used
  • Secure the new battery – be careful not to ground the terminals to any metal mounting, fixture, or body part
  • Connect battery cables – connect the ground cable last to avoid sparking
  • Terminals are button-type, M8 female – recommended torque is 9.0 Nm (6.64 ft-lb)
  • Inspect the battery cables to ensure they have not been installed in reverse polarity
  • If the battery circuit has a disconnect – close disconnect to reconnect the battery
  • Set the battery to ON

NOTE!:  All cable ends must be connected to battery terminals without any washers between terminal bushings and cable ends.

Terminal burnout is caused by

  • Discharge currents exceeding allowable limits
  • Improper cable installation
  • Improper cable sizing
  • Improper terminal torque

NOTE: Without exception, product experiencing terminal burn out will not be warranted.

Parallel Battery Wiring
To ensure proper balancing and load sharing between parallel batteries refer to the wiring diagram below. Lithium batteries are very sensitive to voltage and undersized battery cables will impede battery and system performance. The thickness (cross section) of cable used should exceed the recommended minimum for the inverter charger installation whenever possible.

Five or more batteries in parallel should be installed using a busbar configuration. In a busbar configuration all battery cable sets should be the same length regardless of the battery’s proximity to the busbar (or combiner box). Actual wiring requirements may vary. Consult with the authority having local jurisdiction.

FIG-15

Commissioning Parallel Systems
When commissioning a system with parallel batteries ensure that all batteries are set to ON before the power electronics are energized.

Networking

AEbus Network
The AEBus is utilized by all networked AES batteries to coordinate all voltage, temperature, and current data. Network Terminators are required for proper functioning of the AEBus network. Care should be taken to ensure they are installed.

Configuration with Power Conversion and Monitoring Devices
AES batteries must be set up to work with the Power Conversion devices in either an Open Loop or Closed Loop configuration. The charge and discharge settings in a Open Loop configuration are set up through the controller for the Power Conversion device at the time of installation. In a Closed Loop configuration, charge and discharge settings are dynamically controlled by the BMS of the AES Battery over a connection with the

Power Conversion device network. Charge sources with compliant J1939 Canbus communications can be used directly with AEBus. All other Closed Loop communication with a Power Conversion device network requires the use of a LYNK Gateway Communication device available from Discover Battery.

For Closed Loop and Open Loop configuration details please refer to the appropriate Application Note for your Power Conversion device available from the discoverlithium.com, or contact your Discover Energy Systems provider for assistance.

Operation

CAUTION: Review operating limits.

On–Off / Reset

  • To set the battery to ON momentarily press the button – the LED will illuminate
  • To set the battery to OFF momentarily press the button – the LED will darken

Charging
Before charging the battery make sure to read and understand the instructions that come with the Power Conversion device. Never attempt to charge a battery without first reviewing and understanding the instructions for the Power Conversion device being used. Do not use or install a battery temperature sensor.

CAUTION: Always make sure the charge curve parameters of the charging device are set to meet the charging requirements of the battery; never charge a visibly damaged battery; never charge a frozen battery.

  1. Connect the Power Conversion device’s charger leads to the battery.
  2. Ensure the charger and battery side connections are tight.
  3. Set the charger to ON
  4. Set the battery to ON

CAUTION: NOT ALL CHARGERS ARE CAPABLE OF CHARGING LITHIUM BATTERIES CONFIRM that your chosen charger is incapable of producing transient spikes that exceed the published terminal voltage limits for the battery.

Spikes are fast, short duration electrical transients in voltage (voltage spikes), current (current spikes), or transferred energy
(energy spikes) in an electrical circuit. Voltage spikes usually happen when the AC/DC adapter is plugged in, or charge current is cut off quickly. Multi voltage chargers are constructed using transformers that may be capable of producing spikes that exceed the maximum ratings of the Discover AES Battery. You must ensure that the charger being supplied:

  • Meets the recommended charge curve
  • Incapable of exceeding Discover’s maximum terminal voltages

Open Loop Charge Curve

  1. Charge at constant current to 3.4 V per cell module (Bulk).
  2. Maintain constant voltage 3.4 V per cell module (Absorption).
  3. Terminate when charge current drops below 2A.
  4. Optional Float at 3.35V per cell module (Float).

CAUTION: Do not charge battery higher than 3.4 V per cell module.
NOTE:  Recommended charge current is 0.5C

Discharging

  • Set the battery to ON
  • Set the load to ON
  • Recommended low voltage cut off: 12 V | 24 V | 36 V | 48 V

NOTE: Do not discharge battery below the recommended minimum operating voltages.
NOTE: Do not discharge battery at rates greater than recommended operating currents.

Storage
Systems should be turned off and stored out of direct sunlight in compliance with the following temperature conditions:

Recommended Minimum:  -10°C / 14°F
Recommended Maximum:  30°C / 86°F

Batteries should never be stored at 100% SOC. Store batteries at approximately 80% SOC and checked monthly to ensure the SOC does not fall below 20%. At 20% SOC the battery will self discharge in approximately 2 months.

CAUTION: Do not store a discharged battery. Recharge battery after every use. Batteries that have self-discharged to a severely discharge state are not recoverable.

Service & Maintenance

Warranty Registration
To register your product you will need the serial number of the battery. Visit discoverlithium.com for registration details.

Inspection
Batteries should be carefully inspected on a regular basis in order to detect and correct potential problems before they do harm. This routine should be started when the batteries are first received.

  • Inspect for cracks in the battery casing
  • Check battery terminals and connections to make sure they are clean, free of dirt, fluids and corrosion
  • All battery cables and their connections should be tight, intact, and NOT broken or frayed
  • Replace any damaged batteries
  • Replace any damaged cables
  • Ensure correct torque is used for the terminal bolts

Battery Firmware
Consult the Discoverbattery.com website for the latest battery firmware versions. If a battery firmware update is require, ensure this is done by a qualified and authorized person using the AES Dashboard software tool.

Troubleshooting

If you have not already, read the manual. Most troubleshooting needs arise from misuse, or a failure to understand installation and operating instructions.
As soon as possible, record the condition of the system at the time the problem occurred so you can provide details to help aid in troubleshooting.
Download the separate data log from each battery using the AES Dashboard software tool and have the file(s) ready to share with technical support.

Check the Fuse
Check the fuse. If the fuse is blown (open) it requires replacement.

Review Voltage
Was the battery stored or left for a long period of time at low voltage? The battery may be self discharged and damaged beyond repair.
Was the battery charged above BMS protection voltage? The BMS will have likely disconnected the battery. The battery needs to be left to rest until the high voltage has dissipated. The battery will operate again when the BMS detects that voltage is within safe operating parameters for at least 120s. Note that the charging device’s voltage needs to be reduced in order not to repeat this fault.
Was the battery discharged below low voltage cut-Off? The BMS has likely disconnected battery. The BMS will not reconnect the battery after a low voltage disconnection. Disconnect all loads, set the battery to ON and then charge the battery.

Review Temperature
Was the battery operated above BMS protection temperature? The BMS will have likely disconnected the battery. The battery needs to be moved to a cooler environment and left to rest until the high internal temperature has dissipated. The battery will operate again when the BMS detects that internal temperature is within safe operating parameters for at least 120s.

  • Was the battery operated at high current in a moderate to high temperature?
    The BMS will have likely disconnected the battery. High current operation can increase the internal battery temperature above ambient temperature.

  • Was the battery operated below BMS protection temperature?
    The battery needs to be moved to a warmer environment and left to rest until the low internal temperature increases. The battery will operate again when the BMS detects that internal temperature is within safe operating parameters for at least 120s.

Review Current

  • Did the BMS protect against over current when an inverter was turned ON?
    A large capacitor bank in the inverter likely tried to draw amps in excess of the battery’s peak power rating and the BMS has disconnected the battery. Increasing the number of batteries in the battery bank will help support a high peak amp draw, or surge current.

  • Did the BMS protect against over current when a motor was turned ON?
    The initial surge current required to start the motor is likely in excess of the battery’s peak power rating and the BMS has disconnected the battery. Increasing the number of batteries in the battery bank will help support a high peak amp draw, or surge current level.

  • Is the battery bank undersized as compared to the peak surge requirements of the system?
    Increasing the number of batteries in the battery bank will help support a high peak amp draw, or surge current.

Reverse Polarity
Was the battery exposed to reverse polarity? If the battery cables were attached in reverse polarity the BMS will likely be damaged beyond repair and will require replacement. Contact your dealer and have a qualified and authorized person replace the BMS.
