SYSTEM AND METHOD FOR TEMPERATURE CONTROL OF MULTI-BATTERY SYSTEMS

摘要

An system includes a first battery having a first desired operating temperature range between a first lower threshold temperature and a first upper threshold temperature and a second battery having a second desired operating temperature range between a second lower threshold temperature and a second upper threshold temperature. The system further includes a temperature control system coupled to the first and second batteries and configured to convey heat energy from the first battery to the second battery when the temperature of the second battery is less than the second lower threshold temperature to increase the temperature of the second battery toward the second desired operating temperature range and to convey heat energy away from the second battery when the temperature of the second battery is greater than the second upper threshold temperature to decrease the temperature of the second battery toward the second desired operating temperature range.
