Device for improving a battery's charging capacity has a battery heat exchanger fitted with a heat-conductor link to a battery and integrated in an internal combustion engine's coolant circuit

摘要

Integrated in an internal combustion engine's (1) coolant circuit branch for heating a motor vehicle's passenger area, a battery heat-exchanger (16) maintains a heat-conducting connection with a vehicle's battery (14), connects in series with a passenger area heat exchanger (9) and has a series-connected valve for altering coolant throughput. An Independent claim is also included for a method for improving the charging capacity of a motor vehicle's battery.
