There are generally two kinds of charging methods for household electric vehicles: low-voltage slow charging and high-voltage fast charging. Low voltage slow charge can be charged directly with civilian 220V voltage, slow speed, little damage to the battery system, suitable for overnight charging after going home. High-voltage power supplies are generally used for fast charging. Now there are some pilot charging stations in big cities to promote pure electric vehicles, similar to gas stations, that is, the use of high-voltage fast charging, such as BYD e6, nominal 15 minutes can be charged 80%.
The most important thing for new energy vehicles is the supply of energy to the car, that is, charging, and whether to buy pure electric vehicles or plug-in hybrids, how to charge electric vehicles at home has been the most discussed topic, especially without a fixed parking space, no charging pile, how to safely and correctly charge the vehicle has become the trouble of many owners.
If the vehicle needs to be charged when there is no fixed charging pile at home, you can first use the public charging pile, and then use the charging pile in the unit, if there is no, you can only use the way of flying line charging.
For flying line charging, this is the current way for many owners without fixed charging piles, whether it is pure electric vehicles or plug-in hybrid models, they have slow charging conditions, especially fast charging pure electric vehicles also have slow charging conditions. In the case that the charging conditions are not met, if you want to charge the vehicle, it can actually be achieved by means of plugs, which we call flying line charging.
Of course, if you live in a high-rise, then you have to throw a 220 volt household electricity from home to charge the downstairs vehicle, the cost of charging is relatively high, and there will be some safety problems.
Therefore, electric vehicles can be charged with 220V electricity at home, but the plugboard must be 4000 watts, the maximum voltage is 220 volts or above, and the maximum current is 16 amps or above, that is, the high-power wire board dedicated to air conditioning.
Only special boards for high-power equipment such as air conditioners will be 4,000 watts and 16 amps. However, the power and other indicators of the charger of the general electric vehicle are higher than the rated power of the ordinary household plug-in. For example, in the manual of the Jiangjun car, it is clearly stated that 2000 watts of rated power is required. General household desk lamp small plug board is not recommended.
