Why Can't New Energy Vehicles Be Charged at Home?
2 Answers
It is best not to charge new energy vehicles at home. Generally, the voltage of household electricity is relatively low. If the vehicle is charged during normal use, it can easily cause a short circuit, which can lead to significant hazards. The only safe way to charge new energy vehicles now is to install a charging pile. As long as it is approved, placing a charging pile next to the parking space in the residential area is both convenient and safe. New energy vehicles have high battery capacity: Household electricity cannot achieve fast charging for new energy vehicles, mainly due to the high battery capacity and power limitations. Due to the vehicle's own weight and high driving speed, the drive motor requires sufficient power, and to increase the range, the battery capacity must also be increased. Different rated power: The household charging cable configured for the car also requires the use of a 16A air conditioning socket, and the rated charging power is only 3kW. Electric vehicle charging methods include fast charging and slow charging. Fast charging refers to using a charger with a high charging current and short charging time, which requires going to a specialized location (i.e., a charger that matches the vehicle's charging management system). Slow charging uses household 220V and can be done anywhere with a socket. New energy vehicles refer to vehicles that use unconventional automotive fuels as power sources (or conventional automotive fuels and new automotive power devices), integrating advanced technologies such as vehicle power control and drive, featuring advanced technical principles, new technologies, and new structures.
After driving a new energy vehicle for so long, I've found that home charging has quite a few issues. The key problem is the need for specialized charging equipment - ordinary household sockets provide weak current and charge too slowly, only filling half the battery overnight. When you need the car urgently, you're left waiting. Older houses with aging wiring pose significant risks; forcing a charge could trip the circuit or even cause a fire, requiring electricians to upgrade the wiring at additional cost. Some apartments or residential complexes don't have fixed parking spots, and property management prohibits installation to avoid occupying public resources. As a result, I now rely on public charging stations, which are convenient but add extra driving time. In the long run, home charging is a viable solution, but the initial investment including installation fees and permit applications starts at several thousand yuan.
