- Page 2 BCU-PPAK INSTALLATION MANUAL BCU-PPAK Features - Simple to install and use, microprocessor control. - Low power requirement, just 15mA when switched on with relay active. - Prevents overcharge and over-discharge of LFP batteries. - 12V (4 cell) operation. - 240A (or 3 x 80A) capacity with normal relay, 500A capacity with optional high power relay.
- Page 3 Every effort has been made to make this apparatus as reliable and robust as possible. However electronics can fail. The BCU-PPAK is designed to be the last line of battery protection and should not be relied upon to disconnect the battery under normal operating conditions.
- Page 4 BCU-PPAK INSTALLATION MANUAL How it works - Usage The BCU performs a number of functions: 1) It monitors the battery voltage, if the voltage falls below 11.6V or rises above 15.0V (4 or 5 red LED flashes) for more than 15-20 seconds the relay will open. Then will be no LEDs and the BCU will revert to a low power mode.

Page 5: Battery Storage
Continuous charging is not recommended during storage. The new BCU-PPAK+4C (or 8C) is meant to be set to 11.6V low voltage cut on the main contactor. It should be calibrated +/- 0.1V. - Page 6 BCU-PPAK INSTALLATION MANUAL PAGE 6 OF 13...

- Page 8 BCU-PPAK INSTALLATION MANUAL High Power Applications For batteries in parallel one pole of the relay is required per battery to prevent high current damage if one cell fails in one pack. The standard relay has three poles which may be used to control up to three battery packs in parallel. Just remove the copper bus bar from the battery side of the relay.
- Page 9 A very few types of charger have a remote enable connection. This is a two pole terminal block. If the poles are bridged then the charger will activate. If open circuit then the charger is disabled. It is a useful function which the BCU-PPAK can used to enable the charger.
- Page 10 BCU-PPAK INSTALLATION MANUAL General Battery Guidelines LFP cells should be housed in a battery box away from dust, excessive heat and moisture. Appropriate restraints should be used that are capable supporting at least 5 times the battery weight in the event of a vehicle rollover. All restraints should be well insulated so as not to short out battery terminals.
- Page 11 The handles of metal tools should be insulated with heat shrink or plastic duct tape. DO NOT ALLOW YOUR BATTERY TO RUN DEAD FLAT. IT MAY BE PERMANENTLY DAMAGED AND EV-POWER CAN TAKE NO RESPONSIBILITY FOR THIS. THE BATTERY SHOULD BE CHARGED ONCE A MONTH IF BEING STORED.

BCU-PPAK INSTALLATION MANUAL Alternators are a special case for charging. They often charge at higher currents so should be set lower to minimise the chance of battery disconnection under charge. The Balmar MC-614 regulator says that in the programming the Absorption voltage must be less than the bulk voltage and by a minimum of 0.1 volt. -
Page 13: Important Notes
BCU-PPAK INSTALLATION MANUAL above 2.5V and the BMS will allow normal charging to commence. Care must be taken with the first few charges as the battery may be severely unbalanced. A visual check of the battery pack during charging should be made every 3 months. Switch off the BCU and on again to check that the contactor is operating correctly.
