Product Description

This approved PFC Charger is suitable for charging lithium ion battery packs such as those used in the V2 KOTOTAMA Built by Custom Electronics.

The charger is optimized to work with the V2 Intelligent Battery Management System (iBMS™) for safe battery charging.

Standard safety features include protection against a short circuit on the charger output, reverse polarity,
over charging, over temperature, etc.

3. Charging Status and Alarm Status Indication

3.1 1 Alarm Indication

• Reverse polarity or low voltage: light blinking, 20% light on

• Charger over heating: light blinking, 40% light on

• Ambient temperature too high: light blinking, 60% light on

• Charging time out: light blinking, 80% light on

3.2 Charging Status Indication

• Shutdown status: Six lights blinking

• Charging stage: Percent light indicating pack voltage vs. max charging
- voltage

• Battery presence not detected: Red light blinking, 20% light on

• Charging complete: All green lights on

4. Functions

4.1 Output short circuit protection.

4.2 Over-temperature protection: Temperature less than 85°C – Full charging power
Temperature is 85°C to 95°C – Power reduced to 50%
Temperature is greater than 95°C – No output

4.3 Reverse polarity protection: charger will not turn on if the battery pack is connected backwards (or
less than 5V).

4.4 4 A switch on the charger marked “Override” is used to select either external or internal
controlled charging.
Override Off – Use with BMS system, either CAN or digital input
Override On – Charger program based on pack voltage only (recommended for use with V2 iBMS only).

4.5 When external control is selected and a CAN signal is used, if any cell reaches the recharge set point
(default 3.7V as signaled by a BMS) the charger will automatically enter the final recharge cycles.

4.6 Recharge cycles.

When the iBMS™ detects any cell has reached the recharge set point (default 3.7V)
or above, the charger reduces the charge current to zero amps for five minutes to allow the BMS to
balance the battery pack. The charge will resume after five minutes at half the previous charge current
and will again charge until it receives a signal from the BMS that a cell has reached the recharge set
point. These recharge cycles continue until the charging current reaches the minimum charging current
to complete the charging process.

4.7 Digital alarm input:

0.0V – 2.0V: Charging stopped
2.5V – 12.0V: Enable charging or resume charging

4.8 When both CAN and the digital control signals are available the charger is controlled by the CAN communication signal.

5. Connections

5.1 Custom Connector for output. These connectors are keyed to their mating connector only for use with the V2 KOTOTAMA Built by Custom Electronics Inc.

6. Cautions

• Make sure charger voltage output matches to the number of cells in the battery pack.

• Make sure positive output of the chargers is connected to a positive connection to the battery pack, and the negative output of the charger is connected to a negative connection of the battery pack.

• After a complete charge, disconnect the power source from the charger and then disconnect the connection between the charger and the battery pack.

• The V2 iBMS™ system must be used during the charging process to prevent over-charging.

7. Troubleshooting

• The charger must be used in a cool well-ventilated area which is free of dust

• If the charger is not charging unplug the charger from the AC line and battery pack, then check for poor connections, short circuits, over heating conditions as well as alarm status from the Energy Management System.

• If charger does not display any LED’s when plugged in and charging does not occur the fuse may be blow. Unplug the charger from the battery pack and AC line and check the fuse by unscrewing the cap with a #2 Philips screw driver. If the fuse is blown replace with an equivalent size fuse of the same voltage and amperage rating.

• If the charger finishes charging too early make sure that the connection from the charge to the battery pack is good and does not have high resistance.
