Instructions for charging NiCd and NiMH batteries Charger functionality

This charger is a fast charger for NiCd/NiMH batteries. The standard version utilizes a method called -dV detection for charge termination when the batteries are fully charged. This method is based on the fact that the voltage drops over the NiCd/NiMH cells when the batteries are fully charged. This voltage drop is detected when the voltage has dropped a certain percentage from the highest value. If this drop does not occur, the charger has a safety timer which will terminate charging after a given time period to avoid overcharging the batteries.

A few cells may have a voltage drop in the first part of the charge cycle. This is especially true for battery cells which have been idle for a longer period of time. Because of this, a timer is built into the charger which prevents -dV detection the first minutes of the charge cycle.

As the charger is programmable, it is possible that the standard parameters, which this user manual is based on, have been changed. See separate user manual or contact supplier for additional information.

Cautions before charging NiCd and NiMH batteries

• NiCd/NiMH chargers are designed for charging NiCd and NiMH batteries only.
• Make sure you have the correct battery charger for the battery you wish to charge. The number of cells must correspond to the output indicated on the charger. Never charge more battery cells than the charger is made for.
• When charging separate battery cells, avoid charging cells with different rest capacities at the same time.
• Do not attempt to charge batteries that are not rechargeable.
• Please check that the specification for your battery allows for the maximum charge current indicated on the charger. If in doubt, contact the battery manufacturer for details.
• Please check that the specification for your battery allows for the environmental conditions present during charging.

Do not charge batteries at too high or too low temperatures.

• Please ensure correct polarity when connecting to the battery terminals. Reverse polarity connection may, in some chargers (see the charger’s specification), result in a fuse rupturing, leaving the charger useless.
• The charge cycle starts when the charger is connected to the mains.
• If the charger is disconnected from the mains voltage during a charge cycle the charger will start a new charge cycle when it is reconnected to the mains.
• When charging is complete, disconnect the charger from the mains before removing battery connections.

Safety features

The embedded microprocessor & charge program has numerous features for safe battery charging

• The -dV level will adapt to the number of cells and will be approximately equally sensitive for all number of cells.
• The safety timer will protect the batteries if a -dV signal fails to appear during charging. It is normal to have a safety timer that is longer than the max. charge time.
• Some battery cells may give a voltage drop during the initial part of the charge cycle. To avoid interruption of the charge cycle the charger has a timer that prevents -dV detection during the first minutes of the charge cycle.
• The charger is programmed to disregard large voltage fluctuations due to connection of external loads etc. Such false -dV signals will be detected by the software and will be disregarded.
• Top-off charge following –dV detection ensures that all cells in a battery pack reaches full capacity (are balanced) prior to trickle charge.
• The charger output is protected against reverse polarity, in most cases by an automatically resettable fuse.
• The charger is designed for the lowest possible leakage current from the battery when mains is disconnected (<1mA). Even so, it is recommended that the batteries are disconnected from the charger when mains is not connected.
• On request the charger may be supplied with battery temperature monitoring. A built-in temperature change control (+dT/dt) secures optimal charge with a built-in NTC resistor in the battery pack.
• Other functions such as 0dV detection and timer only charge is available upon request. Most charge parameters may be altered using an external programming tool. Contact Mascot for details.

How to use the type A charger (CPM)

Start the charger by connecting the battery pack to the charger and then connecting the charger to the mains.

The LED (light emitting diode) will be yellow before the fast charge starts and the LED changes to orange. When the batteries are fully charged and the voltage drops because of the -dV signal from the batteries, the charger will go into a top-off charge mode before it goes over to trickle charge mode. During top-off charge the LED will be green with a short intermittent yellow light. When the top-off charge is completed, the charger will go into trickle charge mode and the LED will be green. The charge current is now reduced to a safe level, which allows the charger to stay connected to the battery without damaging the cells.

If the safety timer runs out before –dV is detected, the charger will go directly to trickle charge mode (no top-off charge) and LED will be continuously green. If the battery voltage is far below normal, the charger will stop the fast charge current and go to trickle charge mode. The LED will then indicate ”error” by flickering green and orange light.

You may manually start a new charge cycle by disconnecting mains input and connecting it again.

To charge another/next battery pack, first pack must be disconnected for approx. 15 sec. When LED is yellow, you may connect the next battery.

LED indications

When the mains is connected the LED will be orange for the first seconds and then turn to yellow when the initialisation and analysis starts. If a battery is connected, the actual charging will start a few seconds later when the LED changes to orange. After the start-timer period has run out (the first few minutes of the charge cycle when the –dV detection is disabled), the LED will be green for approx. 8 seconds. This is a signal for testing and service only. When -dV has been detected, the start of the top-off charge is indicated with a green LED with intermittent yellow flashes. The LED is green during trickle charge.

Temperature control (optional feature)

If the charger is used with a temperature sensor (NTC-resistor in the battery) it is possible to add temperature control to the battery charging process. If the battery temperature is too low (< 0°C) at the start of the charge cycle, the charger will charge with low current until the temperature level is safe. This is indicated by an intermittent orange flash while the LED is green. Charger will also enter low current wait mode if battery temperature is above 40 °C. The current will then remain low until the temperature is at a level where fast charge can start. If battery temperature exceeds max. charge temp. (60 °C) charger enters error mode. The LED will show ”error” by intermittently flashing orange and green. By using the temperature increase control (+dT/dt), the charger will switch to top-off charge and later to trickle charge the same way as charging with -dV control.

NOTE. The charger may be programmed for other temperature parameters. See a separate user manual or contact supplier for additional information.

Zero dV feature (optional feature)

If zero dV has been activated, the charger will stop the fast charge when the voltage has not increased the last 5 minutes. This feature may be the only sensor, or it may be used in combination with -dV and/ or +dT/dt

How to use the type B charger (CBC)

Start the charger by connecting the battery pack to the charger and the charger to the mains. The LED indicator will be flashing green if no battery is connected. When the battery is connected to the output of the charger the LED will be yellow and remain in this state until battery is fully charged, and fast charge is terminated. Charger apply low current soft start on deeply discharged batteries. If voltage does not reach normal level within a certain time, charger will enter error mode, shown by 4 red flashes in the LED.

When –dV, +dT/dt or other EoC method is detected, the charger enters top-off mode. This is controlled overcharge to make sure all cells are fully charged. LED indication is flashing yellow.

After top-off period is ended the LED indicator will change to green showing that battery is fully charged. The charge current is now reduced to a safe level, which allows the charger to stay connected to the battery without damaging the cells. Several options for trickle charge are available.

If the safety timer run out before -dV (or +dT/dt) is detected, the charger will go directly to trickle charge mode (no top-off charge) and LED will be green.

You may manually start a new charge cycle by disconnecting mains input and connecting it again.

Temperature control (optional feature)

If the charger is used with a temperature sensor (NTC-resistor in the battery) it is possible to add temperature control to the battery charging process. If the battery temperature is too low (< 0°C) at the start of the charge cycle, the charger will enter no current wait mode until the temperature level is safe. This is indicated by yellow LED with 1 red blink. Charger will also enter wait mode if battery temperature is above 40 °C, and this is indicated by yellow LED with 2 red blinks. The charger will be in no current wait mode until the temperature is at a level where the charging can start. If the temperature is too high for safe charging (> 60°C), the LED will show ”error” by 5 red blinks. When using the temperature increase control (+dT/dt), the charger will switch to top-off charge and later to trickle charge the same way as charging with -dV control.

NOTE. The charger may be configured for other temperature parameters or contact supplier for additional information.

Zero dV feature (optional feature)

If zero dV has been activated, the charger will stop the fast charge when the voltage has not increased during specified time. You may use 0dV alone or in combination with -dV and/ or +dT/dt. This function is normally only used in special cases.
