When it comes to electric vehicles, everyone will think about the difficulty of charging. These problems focus on too few charging piles and inconvenient charging. Now let's talk about the electric charging problem.

        In fact, electric vehicles can be directly charged on the home 220V circuit, and those misunderstandings that must be charged with a charging pile are entirely attributed to the one-sided publicity of traditional car dealers.

        The reason why electric vehicles need to be charged with charging piles is because the chargers equipped with new energy vehicles are relatively slow to charge, and the new energy vehicles need to charge a large amount of electricity, which is about 18 degrees. The charger equipped with the car is relatively small, and it is about 10 hours, but the advantage of this charging is that it does not hurt the battery, and the TV has a longer service life.

        However, the market has also appeared 3.3KW household portable car charging guns. These chargers can be used in household 220V circuits, and the charging time can be shortened to 5 hours. Of course, you need to choose a big brand and high security products.

If you have a garage in your home or if parking conditions permit, it is most convenient and cost-effective to charge at home. The charging station is a high-current high-voltage fast charging mode, charging time is short but has an impact on battery life. Home charging is a low-voltage slow charging mode, using a small current, although long time is beneficial to battery life.

     When the consumer buys a car, the manufacturer will give away a household charger. However, the charging power of this car charger is relatively low, such as BYD's car charger power is only 1.6KW, taking BYD Song DM as an example, Song DM battery capacity is 16.9kWh, using the supplied car charger, full The electricity needs 16.9kWh/1.6KW=10.5 hours, and this charging speed is really slow.

   The maximum current of 220V household electric load is 16A, and the maximum charging power is 220V*16A=3.5KW, which means that the power of charging in household circuit can be improved, but it can't be higher than 3.5kw. Currently, Taobao and Tmall There are already a lot of 3.3KW household portable car charging guns on sale, which is a good choice for electric car home charging. The price of this charging gun is between $200-$480. With this charging gun, the full charge time can be shortened to 4-5 hours.
