Detailed Description

How long does it take to charge an electric vehicle for normal use? For example, take a taxi as an example: the capacity of the battery pack is 80kW/H, and the power of the charging pile is 120kW. In the mode of simultaneous use of two guns, the single gun is 60kW -- 80kW. H ÷ 60kW=about 1 hour and 20 minutes; Output 120kw ----- 80kw in single gun mode. H ÷ 120kw=about 45 minutes.

First of all, should we clearly distinguish between electric vehicles and traditional fuel vehicles? It is well known that fuel vehicles provide power mainly by adding fuel to the engine and gearbox; Electric vehicles are mainly driven by DC motors and battery packs. Other principles are basically the same.



In addition, the DC charging pile is mainly composed of modules, main control board, communication board, human-computer interface, charging gun, billing system, air switch, lightning protection, anti discharge, insulation detection, etc. The approximate driving distance of electric vehicle is 30-90KW, h, and the driving mileage is 200-500km; Of course, the higher the power of the charging pile, the faster the charging speed. For example, the capacity of the car battery pack is 60kW/H, the charging time of the 80kW charging pile is about 1 hour, and the charging time of the 120kW charging pile is about 0.8 hours. Strictly speaking, the charging speed is determined by the performance of the battery. The battery itself does not repel the external charging current and cannot be controlled. However, high current charging will generate a lot of heat for the battery. If it cannot be cooled in time, the battery will be damaged. Therefore, the BMS system will increase the real-time effective control and limitation of charging power and current to achieve the best state. When the charging power is too high and exceeds the limit value controlled by the BMS, no matter how high the charging power is, it is invalid.



How many charging ports do pure electric vehicles have? Generally speaking, hybrid passenger vehicles only have one AC charging port; The pure electric passenger vehicle has two charging ports, one is the AC interface (connected to the AC pile), the other is the DC interface (connected to the DC pile); The bus is just a DC interface. Since the maximum current of a single DC charging gun is 250A, buses with large battery pack capacity will have multiple DC charging ports. Finally, what are the classifications of electric vehicle batteries? Among them are lithium iron phosphate battery, ternary lithium battery (widely used in passenger cars), lithium titanate (Yinlong, etc.).
