The hybrid electric hybrid vehicle has high fuel economy performance and superior driving performance. The engine of the hybrid vehicle uses fuel, and at the time of starting and accelerating, due to the assistance of the electric motor, the fuel consumption can be reduced. Simply put, It is a lower fuel cost than a car of the same size. 1. Add fuel to the gas station like a gasoline car, without changing the habits of the car; the government and enterprises do not need to invest in new charging devices or gas stations. 2, fuel economy performance is high, and the driving performance is superior, the engine of the hybrid vehicle should use fuel, and at the start and acceleration, due to the assistance of the electric motor, the fuel consumption can be reduced, the internal combustion engine can be shut down, and the battery is driven separately. Achieve “zero†emissions. 3. The power is better than the single-combustion engine of the same displacement. Especially when starting acceleration, the motor can effectively compensate for the weakness of the low-speed torque of the internal combustion engine. 4. Reduce the mechanical noise in the car, use the motor when running at low speed or idle speed. 1. The technology is immature, the related products are overpriced, and the cost of the two sets of power systems of electric motors and internal combustion engines is much higher than the cost of a set of power systems. 2, long time high speed or constant speed driving is not fuel efficient. Because the advantage of hybrid vehicle fuel consumption mainly depends on the energy storage energy saving, in other words, the more frequent the vehicle slows down during driving, or the frequent start of parking, it will be relatively more energy efficient. If you are driving at a constant speed for a long time, the energy saving effect will be reduced accordingly. The power system of a hybrid electric vehicle is mainly composed of a control system, a drive system, an auxiliary power system, and a battery pack. Take the series hybrid electric vehicle as an example to introduce the working principle of the hybrid electric vehicle. At the beginning of the vehicle, the battery is fully charged, its energy output can meet the requirements of the vehicle, and the auxiliary power system does not need to work; When the battery power is lower than 60%, the auxiliary power system starts: When the vehicle energy demand is large, the auxiliary power system and the battery pack simultaneously provide energy for the drive system; when the vehicle energy demand is small, the auxiliary power system supplies energy to the drive system and also charges the battery pack. Due to the presence of the battery pack, the engine is operated in a relatively stable condition, resulting in improved emissions. Not all hybrid vehicles rely on electric motors, batteries and wires. Some vehicles are driven by a combination of a hydraulic engine, a bell line and an accumulator. Hybrid car batteries can basically be divided into three-element lithium batteries, lithium iron phosphate batteries, and nickel-hydrogen batteries. The first two are lithium-ion batteries, the ternary lithium battery has a cycle life of less than 1000 times, and lithium iron phosphate is about 2000 times. It is used in a hybrid car for 10 years and 200,000 kilometers. The pressure is not large, even if there is damage to the monomer. The replacement cost is not high, a few hundred dollars a piece, the overall replacement will not appear in the life cycle. Nickel-metal hydride battery Toyota hybrid has been in use, the service life is about 500 cycles, it is ok to do 1000 times under the premise of shallow charge and shallow release. Toyota uses the energy management system to achieve shallow filling and shallow release, Prius as an example, There are also a lot of batteries that have not been moved for 100,000 kilometers. With the super long warranty of the hybrid car battery, you can buy it with confidence, without worrying about battery life. Hybrid vehicles have a design life that is the same as the life of the car. For example, the Japanese hybrid Prius is a taxi and does not need to maintain the power system for 400,000 kilometers. Toyota's oil-electric hybrid battery does not pursue large capacity. But the pursuit of high life. Because it does not rely on battery capacity for battery life. The domestic BYD electric car is pursuing a large capacity. You can drive 100km on battery only. However, you need to change the battery after charging and discharging thousands of times. Tens of thousands. Very expensive. Oil-electric hybrid Camry or Prius and even higher-end Lexus, fully charged within 10km. The capacity is small, but the lifespan never needs to be considered. You take it completely as a petrol car. However, your problem is in case your battery accident is damaged. Change one piece. It is also a thousand things.
