What is the charging power of a home charging station?
2 Answers
The charging power of a home charging station is approximately 6.6 kilowatts. Functions: The charging station (socket) can achieve timed charging, electricity metering, and cost calculation, serving as a terminal for citizens to purchase electricity. Meanwhile, to enhance the efficiency and practicality of public charging stations (sockets), functions such as multi-vehicle charging per station (socket) and charging for electric bicycles will be gradually added in the future. Technical Implementation: As an energy replenishment device for electric vehicles, the charging performance of an electric vehicle charging station is related to the service life of the battery pack and the charging time. This is also one of the aspects that consumers are most concerned about before purchasing an electric vehicle. The basic principle of electric vehicle charger design is to achieve fast, efficient, safe, and reasonable power replenishment for power batteries. Additionally, the applicability of the charger to various power batteries must be considered.
My home charging station has a power output of around 7 kilowatts, which is sufficient for most regular electric vehicles. It's not too high nor too slow, allowing most car batteries to be fully charged overnight. The power range for home charging stations is actually quite broad, ranging from basic 3.3 kilowatts to high-efficiency 22 kilowatts. The choice depends on what the vehicle supports and the household electrical grid conditions; for example, lower power options like 3.3 kilowatts are suitable for older residential areas, charging more slowly but steadily. Higher power options such as 11 or 22 kilowatts charge faster but may require upgrading the meter or additional wiring, potentially costing more. I find the mid-range 7 kilowatts to be the most hassle-free, being both safe and economical. Before installation, it's best to have a professional assess your home wiring's load capacity to avoid overload and damage. Maintenance is simple—just keep the socket dry. Charging power affects charging speed; lower power means longer charging times, but it doesn't harm the car's battery, making it quite practical.
