What is the difference between fast charging and slow charging of electric vehicles? What is the difference between fast charging and slow charging of electric vehicles?
Fast charging is the charging interface of DC charging pile, which converts the AC power supply of power grid into DC power supply and delivers it to the fast charging port of electric vehicle, and the electric energy directly enters the battery for charging. Slow charging is the charging interface of AC charging pile. Alternating current from the power grid is input to the slow charging port of the electric vehicle, converted into DC power supply by the charger in the vehicle, and then input to the battery to complete charging. In fact, fast charging and slow charging of new energy vehicle batteries are relative. In the fast charging mode, the battery is charged by high-power DC, and it can be fully charged with 80% power within one hour. Slow charging refers to AC charging. Generally speaking, it takes 6 to 8 hours for the vehicle to fully charge the battery. At first glance, fast charging saves a lot of time than slow charging. For new energy vehicles, fast charging is only a way of emergency. At this time, the DC voltage is generally greater than the battery voltage, so in the fast charging mode, higher requirements are put forward for the voltage resistance and protection of the battery pack of new energy vehicles, because in the fast charging mode, the current is several times or even dozens of times as usual. For ordinary families, slow charging refers to charging with household 220 volts alternating current. For safety reasons, the charging current of slow charging is generally less than 10 amp, while the maximum power of slow charging is 2.2 kW, which is several times smaller than that of fast charging. So we can draw a conclusion that slow charging has no advantage in time, but it is beneficial to the battery. After all, the load of the battery is much less, and slow charging is beneficial to the life of the battery.
The function of inverter in electric vehicle
Functions of automotive power inverter:
1. Vehicle-mounted inverter (PowerInverter) is a convenient vehicle-mounted power converter, which can convert DC 12V into AC220V which is the same as the commercial power for general appliances. Vehicle-mounted power inverter is very popular in foreign markets. In foreign countries, because of the high popularity of cars, when going out to work or travel, you can use inverters to connect batteries to drive electrical appliances and various tools to work.
2. After China's entry into WTO, there are more and more private cars in the domestic market. Therefore, as a DC-to-AC converter used in mobile, the vehicle-mounted inverter power supply will bring a lot of convenience to your life, and it is a standing automobile electronic appliance. The vehicle inverter output by the cigarette lighter can be 20W, 40W, 80W, 120W to 150W.
3. The inverter power supply with high power should be connected to the storage battery through the connecting wire. Connect household appliances to the output end of the power converter, and you can use all kinds of appliances in the car as conveniently as at home. Electrical appliances that can be used include: mobile phones, notebook computers, digital video cameras, cameras, lighting lamps, electric shavers, CD players, game machines, handheld computers, power tools, car refrigerators, and various travel, camping, medical first aid, etc. What is the difference between fast charging and slow charging of electric vehicles?
