Title: Charging controller
Inventor: YOKOYAMA HIDENORI
IPC: B60L11/18
Filed: 2001-06-04
Abstract: PROBLEM TO BE SOLVED: To swiftly enhance charging acceptability, when the temperature of a battery is low. SOLUTION: A battery which performs charge and discharge between the battery and a M/G(motor-generator) via an inverter is provided. When the temperature T of the battery is low, a frequency f of a charging voltage which is applied between its terminals when the battery is charged by the M/G, is set to a frequency lower than in the case where the battery temperature T is higher. More specifically, the period of the driving duty of the inverter is made longer. Since the internal resistance of the battery becomes higher the lower at the frequency f, power consumption increases by losses through heat generated, when a current flows, and the temperature of the battery becomes easy to increase, if a charging voltage is applied to the battery at a low frequency. Consequently, charging acceptability can be enhanced swiftly when the battery temperature T is low.
