What is the general power of slow charging for cars?
2 Answers
Most of the slow chargers available in the market are 37.5kW. Here is some relevant information about electric vehicle charging: Precautions: If the charger gets wet, it can easily burn out the circuit board and control components, and human contact may cause irreversible harm. Additionally, water in the charger can lead to electronic component failures. If the charger remains in operation, it may overcharge the battery, causing damage. Charging instructions: Charge according to the battery capacity, which generally takes 8-10 hours to fully charge. Disconnect the power promptly after full charge. If the power remains on for an extended period, the electronic components inside the charger may overheat, potentially causing a short circuit and sparks, which can lead to a fire. Fires are most likely to occur at night and in the early morning, so it is best to charge during the day with supervision. Once the indicator light on the charger turns green, it should be unplugged as soon as possible. The charging environment should be well-ventilated, with an optimal temperature of 25 degrees Celsius. Avoid exposing the vehicle to direct sunlight or rain during storage.
The power of slow charging typically fluctuates between 3 kW and 7 kW, depending on your charging equipment and the car model. The home charging station for my electric car is 7 kW, connected to a 240-volt circuit, and it can fully charge from empty overnight—much slower than fast charging but better for battery protection. For example, a standard household 220V socket can only reach 2.3 or 3.3 kW, making the process even longer. Why is it called slow charging? Because it uses lower current, takes more time but is safer and gentler on the power grid. I think choosing a charging station depends on whether your home circuit supports it; older houses might need an electrical upgrade to avoid overload. In short, the actual power usually starts at 3 kW, with a maximum around 7 kW, and each charge takes at least eight hours—ideal for overnight charging while parked.
