The principle of power recovery system for new energy vehicles can be summarized as follows:
1. Energy conversion and storage: When a new energy vehicle decelerates or brakes, the vehicle's kinetic energy that would otherwise be wasted is converted into electrical energy. During this process, the driving motor is precisely controlled to switch to generator mode. The generator uses the mechanical energy generated by braking to generate electricity, which is then stored in a high-voltage battery for subsequent use. This conversion and storage mechanism achieves effective energy recovery and reuse.
2. System working principle: During the operation of a new energy vehicle, when the driver releases the accelerator pedal or lightly steps on the brake, the system will detect a decrease in vehicle speed and automatically activate the energy recovery mode. At this time, the electric motor is reversed and used as a generator to generate electricity by recovering the inertial kinetic energy of the vehicle. At the same time, the vehicle's braking system will also work together to ensure safe deceleration of the vehicle. The recovered electrical energy is converted into direct current suitable for storage in batteries through inverters or other power electronic devices, and stored in high-voltage battery packs.
3. Application and benefits: The power recovery system of new energy vehicles not only improves the vehicle's energy utilization efficiency, but also significantly extends the vehicle's range. By reducing energy loss during braking, this system helps to lower vehicle energy consumption and emissions, which has a positive impact on environmental protection. The power recovery system also helps to reduce the burden on the braking system, decrease the wear and replacement frequency of brake pads, and thus lower the maintenance cost of the vehicle.
The power recovery system of new energy vehicles achieves effective recovery and reuse of vehicle kinetic energy through clever energy conversion and storage mechanisms, providing strong support for energy conservation, emission reduction, and long range of new energy vehicles.
