1. A system comprising:

  • a high-specific energy battery having a first operating temperature range between a first lower threshold temperature and a first upper threshold temperature;

    a high-specific power battery having a second operating temperature range between a second lower threshold temperature and a second upper threshold temperature, wherein the second upper threshold temperature of the high-specific power battery is less than the first lower threshold temperature of the high-specific energy battery; and

    a temperature control system comprising a heat exchanger system, the heat exchanger system coupled to the high-specific energy and high-specific power batteries, wherein the temperature control system is programmed to;

    convey heat energy from the high-specific energy battery to the high-specific power battery through the heat exchanger system when the temperature of the high-specific power battery is less than the second lower threshold temperature to increase the temperature of the high-specific power battery toward the second operating temperature range; and

    convey heat energy away from the high-specific power battery through the heat exchanger system when the temperature of the high-specific power battery is greater than the second upper threshold temperature to decrease the temperature of the high-specific power battery toward the second operating temperature range.
