A plug-in hybrid electric vehicle (PHEV) is a new hybrid electric vehicle. Different from the hybrid power of traditional gasoline power and electric drive, the plug-in hybrid drive principle and drive unit are the same as the electric vehicle. The only difference is that the vehicle is equipped with an engine. A plug-in hybrid electric vehicle has the advantages of low noise and low emissions. 2 plug-in hybrid electric vehicles are between conventional hybrid electric vehicles and pure electric vehicles. When the mileage is long (such as weekend outings), the internal combustion engine-based hybrid mode is adopted, and the travel mileage is short (such as normal commute). In pure electric mode. 3 The external power grid can be used to charge the vehicle power battery during the evening low valley, which not only can improve the efficiency of the power plant generator set, but also can greatly reduce the dependence on oil. At the same time, electricity consumption is cheaper than fuel, which can reduce the use cost. 4 Due to the driving characteristics of the plug-in hybrid electric vehicle, the power battery SOC must fluctuate within a large range, which belongs to deep charging deep discharge, so the cycle working life is affected to some extent, and the power battery needs to have deep charging and deep discharging capability. . In recent years, China's relevant policies on subsidies, encouragement and support for new energy vehicles have also prompted car companies to enter the field. In the eyes of many insiders, the reason why the pure electric vehicles that used to support the front door were caught in the limelight were still related to their current development difficulties. Due to the relatively slow growth of infrastructure, charging has become a real problem that many consumers are temporarily unable to solve. In addition, technical issues such as battery life mileage are also urgently needed to be resolved. In the face of technical bottlenecks, automakers' mass production plans and marketing are also extremely cautious, and the market response has not been effective. In contrast, the plug-in hybrid model effectively solves the problem of the cruising range of pure electric vehicles, and combines the traditional power system with the pure electric power system to make up for their respective disadvantages and maximize the advantages of both parties. In this context, many industry experts believe that plug-in hybrids are more suitable for the current situation than pure electric vehicles. Forecasts show that by 2020, the global sales of pure electric vehicles will reach 1 million; on the other hand, by 2020, the sales of plug-in hybrid vehicles will reach 1.35 million, and by 2025, the global plug-in hybrid The sales of power cars will reach 2.7 million. 2015 or 2016 will be the turning point for plug-in hybrids beyond pure electric vehicles. Plug-in hybrid vehicles are charging that requires charging. But not always charging. If there are more urban traffic, you can drive completely in pure electric mode, which is more environmentally friendly. The difference between plug-in hybrid electric vehicles and ordinary hybrid electric vehicles: ordinary hybrid electric vehicles have small battery capacity, supply/recover energy only when starting/stopping, acceleration/deceleration, and cannot be externally charged, and cannot be used in pure electric mode. Long-distance driving; plug-in hybrid car battery is relatively large, can be externally charged, can be driven in pure electric mode, after the battery is exhausted, then drive in hybrid mode (mainly internal combustion engine), and timely charge the battery . In the absence of electricity, the engine energy is divided into two parts, one is the consumption of the car, and the other is to drive the generator to charge the battery. At this time, the fuel consumption is larger than that of the average car. The so-called hybrid car fuel-efficient, in fact, refers to the engine does not start when driving at low speed, only the motor, because of this high speed motor efficiency, low engine efficiency, it will reduce fuel consumption. If it is a long-distance high-speed drive, the motor is basically ineffective.
