2 pin JST-02T-JWPE-VSLE Car Waterproof Connector Wire Speed Plug Socket Shell Sheath

Figure 2.3 (A) shows the normal driving, starting, or acceleration conditions of the car. At this time, the engine is always running under the best single operating conditions with high thermal efficiency and low emissions, and drives generators to generate electricity. Under the controller adjustment, the electrical energy emitted by the generator is used for motor, and the wheels are driven by the transmission or a reducer. If the generator has insufficient power generation, the battery is also powered by the controller to the motor. Figure 2.3 (b) shows the car taxi, low -speed driving or small load conditions. At this time, the power generation power of the generator is greater than the power required by the motor. Figure 2.3 (C) shows the operating conditions of automobile deceleration and braking. At this time, the motor is converted into a generator, which drives the wheels to drive the motor to generate power and charge the battery (energy recovery). Figure 2.3 (d) shows the short parking conditions of the car. At this time, the engine drives the generator to work and charge the battery.

Figure 2.3 Candidate hybrid vehicle driver mode

It can be seen from the above analysis that during the SHEV operation, the motor is the only driver. The working status of the engine is not affected by the operating conditions of the car. It is always stable in the best working area. The controller controls the generator to charge the battery or the battery. Power power to the motor, that is, the controller coordinate the power of the power generation and the power of the motor by the battery to adapt to various resistance changes in the driving of the car. The existence of batteries allows the engine to work in a relatively stable operating condition to improve its emissions.

(3) The characteristics of series hybrid vehicles.

The main advantage of series hybrid vehicles is that when driving in the city, it can only be driven by the battery pack electric energy to achieve "zero emissions" driving; The discharge of harmful gases is controlled at the lowest range.

There are the following points of the lack of series hybrid vehicles.

① The parameters of driving motors are difficult to choose. In order to be able to overcome the maximum resistance of the car during driving, the power requirements for driving the motor are large, the shape size is large, and the quality is heavier. The capacity of the power battery pack is large. Essence

② There are few applicable models. The huge power battery pack has a large shape and large quality. It is more suitable for use on large passenger cars. It is still difficult to use on medium and small cars.

③ The engine is converted from the chemical energy of fuel to mechanical energy, and then converted to electrical energy. That is, the energy conversion process of chemical energy, thermal energy, electrical energy, and mechanical energy must be passed through fuel, so energy loss is large. In addition, energy loss also exists during the charging and discharge process of the power battery pack. It does not often run in a full load state, and the total energy conversion efficiency is low.

④ The matching requirements of the engine/generator set and the power battery pack are stricter. It should be able to start or turn off the engine/generator set to avoid excessive discharge of power battery packs, which requires a larger battery capacity.

2. Parallel Hybrid Electric Vehicle (PHEV)

(1) The main composition of parallel hybrid vehicle power system.

PHEV is mainly composed of engines, transmission, power generation/motor, inverter, battery pack, driving bridge and other components. Its basic structure is shown in Figure 2.4. The flow direction of mechanical and electrical energy when working is shown in Figure 2.5. Figure 2.5 Double arrows in Figure 2.5 indicate that energy can flow in both directions. For example, the double arrow between the motor/generator and the power storage device indicates that the motor can be driven by electric energy to drive the car. In the electric energy storage. The significant feature of PHEV is that PHEV is driven by the engine and the motor to drive the car through different clutches.

The structural relationship diagram of the parallel hybrid power system. In this system, the engine is 1.4L four -cylinder direct injection diesel engine, the power is 110kW, the continuous power of the permanent magnetic brushless DC electric motor is 75kW, and the 6 -speed dual -clutch transmission. The battery pack providing power supply to the vehicle is embedded in the body structure to ensure its safety. This battery pack with a mass of 125kg is 8.8kW · h, the voltage is 280 ~ 390V, and 50km can be run in pure electric working mode. When the system works at low speeds and small loads, it is mainly driven by permanent magnet motor to drive cars. When working at high -speed large loads, permanent magnetic DC motors and diesel engines drive the car at the same time.
