System and method for temperature control of multi-battery systems
First Claim
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.

Abstract
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.

11. An apparatus comprising:
-
a heat exchange system comprising a first heat exchanger positioned along a first portion of a heat transfer path and a second heat exchanger positioned along a second portion of the heat transfer path; and a controller programmed to; transfer heat energy from a high-specific energy battery to a high-specific power battery through the first heat exchanger along the first portion of the heat transfer path when a temperature of the high-specific power battery is operating at a first temperature such that an operating temperature of the high-specific power battery increases; and transfer heat energy away from the high-specific power battery through the second heat exchanger along the second portion of the heat transfer path when the high-specific power battery is operating at a second temperature such that the operating temperature of the high-specific power battery decreases. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
