Product Name: Toyota Prius Hybrid Car Batteries
What is tandem power?
Series power is composed of engine, generator and motor three-part power assemblies. They are connected in series to form the SHEV power unit system. The engine drives the generator to generate electricity. The power is sent to the battery or motor through the controller, and the motor passes the transmission mechanism. Drive the car. At low load, the battery drives the motor to drive the wheels. When the load is heavy, the engine drives the generator to drive the motor. When the vehicle is in starting, accelerating, climbing conditions, the engine, motor unit and battery pack provide electric energy to the motor; when the electric vehicle is in low speed, coasting, idle conditions, the battery is used to drive the motor, when the battery pack When power is lost, the engine-generator set charges the battery pack. The tandem structure is suitable for frequent starting and low-speed operating conditions in the city. The engine can be adjusted to operate stably near the optimal operating point, and the purpose of adjusting the speed of the vehicle can be achieved by adjusting the output of the battery and the motor. This allows the engine to avoid idle and low-speed operating conditions, thereby increasing engine efficiency and reducing exhaust emissions. But its disadvantage is that the energy is converted several times and the mechanical efficiency is low.
What is hybrid power?
Mixed-type devices include both tandem and parallel types. The power system includes an engine, a generator, and an electric motor. According to the booster device, it is divided into two main engines and two main motors. In the engine-based form, the engine is used as the main power source, and the motor is the auxiliary power source. In the motor-based form, the engine is used as the auxiliary power source and the motor is the main power source. The advantage of this structure is that the control is convenient and the disadvantage is that the structure is more complicated. Toyota's Prius belongs to the motor-based form.
