Control of recuperative braking energy of electric vehicle

摘要

The patent concerns a procedure for controlling the energy recovery from the brakes of an electric vehicle. The vehicle has a battery, connected via a converter to the driving motor, the converter being operated under a pulse width modulation regime. During a braking process, the capacity of the battery to absorb energy is compared with a fixed value. If the capacity is less than that value, the battery is switched into a consumption mode, where its accumulated energy is consumed without the vehicle being accelerated. If the capacity is greater than that value, the battery is switched into energy recovery mode, where the energy recovered is stored in the battery.
