Title:
蓄電器を備えた車両の電力制限装置
Document Type and Number:
Japanese Patent JP4199331
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power limiting device capable of improving the service life and the recovery efficiency of a battery. SOLUTION: This is an electric power limiting device for a vehicle provided with a storage battery. The electric power outputted from the storage battery generates a drive force for running and kinetic energy from running is converted into electric power at braking and stored in the storage battery. This device is provided with a means, which calculates the electric power (step 2) in accordance with the rpm and required torque of a motor or a generator connected with the storage battery, a means (steps 4, 5) which when the calculated electric power exceeds the critical value in the storage battery, calculate the torque of the motor or generator which is capable of compensating the energy loss, at least in the motor or generator based on the critical value and rpm, and a means (step 6) which limits the torque of the motor or generator to the torque so calculated.
