TEMPERATURE RISE CONTROLLER OF BATTERY PACK

摘要

PROBLEM TO BE SOLVED: To solve such a problem that temperature rise control is difficult while a vehicle is running, when temperature rise control is performed by stepping-up/down a step-up/down converter (not shown) for connection with a high voltage battery 10 thereby charging/discharging the high voltage battery 10.SOLUTION: Each module M1-Mm constituting a high voltage battery 10 is connected with an inter-module capacitor Cm via an inter-module matrix converter MMC. When the temperature of the high voltage battery 10 is low, the inter-module matrix converter MMC is operated so that the electric energy of the modules M1-Mm charges the inter-module capacitor Cm or is discharged to a module Mi.
