More and more consumers begin to choose to buy new energy models, and the charging of pure electric models has become the most concerned issue of consumers. Some consumers have installed charging piles in their garages, and provide two functions of fast charge and slow charge. Here consumers will have a question, new energy vehicle charging is fast charge or slow charge?

First, the difference between fast charging and slow charging of new energy vehicles
< br >
In fact, the battery of new energy models fast charging and slow charging is relative, fast charging mode for high-power DC charging, generally within an hour can be filled with 80% of the electricity. Slow charge refers to AC charging, and the average model takes 6 to 8 hours to fully charge the battery. In this way, fast charging saves a lot of time than slow charging.

Second, when to choose fast charge?
< br >
For new energy vehicles, fast charging is just a way of emergency. At this time, the DC voltage is generally greater than the voltage of the battery, so in the fast charging mode, higher requirements are put forward for the voltage resistance and protection of the new energy vehicle battery pack, because in the fast charging mode, the current is several times or even dozens of times as usual.

Third, the benefits of slow charging
< br >
For the average family, slow charge refers to the use of the home 220 volts AC charge. For safety reasons, the charging current of slow charge is generally less than 10 amps, and the maximum power of slow charge is 2.2 kilowatts, which is several times less than the 16 kilowatts of fast charge. Therefore, we can calculate that slow charging has no advantage in terms of time, but slow charging is good for the battery. After all, the battery has a lot less load, and the form of slow charge is conducive to the life of the battery.
Less time costs, less natural charging costs
