Abstract

The invention discloses a braking energy recovery system of an extended range electric vehicle. The braking energy recovery system comprises a brake pedal signal processing module, an accelerator pedal signal processing module, a gear signal processing module, a main cylinder pressure signal detection module, a diagnosis circuit module, a braking energy recovery system control unit (RBSECU), an anti-lock braking control unit (ABSECU), an anti-lock braking (ABS) electromagnetic valve drive module, an anti-lock braking (ABS) pump motor drive module, an integrated starter generator control unit (ISGECU), an integrated starter generator (ISG) motor, a power battery, a battery management system (BMS), a drive motor control unit (TMECU) and a drive motor (TM). Under the premise of ensuring safe braking, the braking energy recovery system of the extended range electric vehicle can recover the braking energy furthest, and improve the vehicle energy utilization efficiency.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a braking energy recovery system for an extended-range electric vehicle, which is used to improve the energy utilization efficiency of the whole vehicle. Background technique [0002] In order to improve the energy utilization rate of the whole vehicle, electric vehicles usually use braking energy recovery technology. During the process of vehicle deceleration, coasting and braking, the driving motor of the electric vehicle is switched to the power generation state, and part of the kinetic energy of the vehicle is converted into electric energy and fed back to the power battery. Thereby realizing braking and energy recovery and reuse. [0003] A Chinese utility model patent discloses a braking energy recovery system (Jiang Yuanguang, Zhong Guohua, Zhang Bingjun. A braking energy recovery system, authorized announcement number: CN 201736828 U, announcement da...
