Abstract
A charge management system and method, within a vehicle having a battery and generation subsystem, is disclosed which senses the temperature of electrolyte in the cells of the vehicle battery and the voltage across the terminals of the battery. The voltage indicates the probability of the existence of excess electrical capacity from the vehicle generation subsystem. In response to a cold temperature and excess power, the system uses the excess power of the vehicle generation subsystem to heat the battery to a desired level. Once the battery reaches the desired temperature level, the system dicontinues the heating of the battery. In the event that there is not excess power, then the system, by maintaining the battery heating element in an off position, does not interfere with the charging of the battery.
