What is the power rating of BYD's home charging station?
2 Answers
BYD's home charging stations come in two power ratings: 7kW and 3.5kW. The power is typically determined by the charging current. If the current is 32A, it's a 7kW charging station; if it's 16A, the charging station's power is 3.5kW. Charging stations are divided into two main categories: AC (alternating current) and DC (direct current). Generally, AC stations have a power rating of 7kW and use a 220V single-phase power supply. DC stations offer multiple power levels to choose from, such as 30kW, 60kW, 100kW, 150kW, and 200kW. The actual charging process depends on the matching between the electric vehicle's battery parameters and the charging station, and it varies with the charging status. Charging stations function similarly to fuel dispensers at gas stations. They can be fixed to the ground or walls and installed in public buildings (such as public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations. They can charge various types of electric vehicles at different voltage levels. The input end of the charging station is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging stations generally provide two charging methods: regular charging and fast charging. Users can swipe a specific charging card on the human-machine interaction interface provided by the charging station to select the charging method, charging time, print cost data, and perform other operations. The charging station's display screen shows data such as charging amount, cost, and charging time.
Last time I bought a car, I chose BYD's charging pile. The standard version has a power of 7kW, which is 7000 watts. It can be plugged into a 220V socket at home, making charging quite convenient. It takes about 8 to 10 hours to fully charge a BYD Han EV, which is sufficient for daily commuting. During installation, it's necessary to have a professional electrician check if the circuit can support 32A current to avoid overheating and potential hazards due to wire overload. If you frequently take long trips at home, you can opt for the high-end version with 11kW or 16kW, which charges twice as fast, but that requires upgrading the circuit at a higher cost. Overall, I find the 7kW version quite cost-effective, and the charging cost is not expensive either—just over ten yuan for a full charge, much cheaper than refueling. It's recommended to regularly clean the socket to prevent poor contact from affecting efficiency. In short, choose the power based on your driving habits and home conditions—don't make unnecessary changes.
