The Han EV's home slow charging uses 220 volts and takes 9 hours; professional charging stations take 15 to 30 minutes. Electric vehicles refer to vehicles that use on-board power as their power source, drive wheels with electric motors, and meet all requirements of road traffic and safety regulations. Features of the BYD Han EV: Dimensions: The BYD Han is a dual-mode electric vehicle with body dimensions of: length 4980mm, width 1910mm, height 1495mm; Interior: Features a 12.3-inch LCD instrument panel and a 15.6-inch rotatable central control LCD screen; provides a total of 6 USB ports (4 in the front and 2 in the rear); Supports mobile phone NFC car key function: Unlock by simply bringing the phone close, no need to power on or connect to the internet. Advantages and disadvantages of pure electric vehicles: Environmental protection: Electric vehicles use power battery packs and electric motors for propulsion, producing no exhaust gases or tailpipe pollution, making them highly beneficial for environmental protection and air cleanliness, almost "zero pollution"; Low noise: Electric vehicles do not produce the noise typical of conventional cars, and the noise they generate is almost negligible; Economical: The operating cost of electric vehicles is low, about one-fifth that of gasoline cars. They also have high energy conversion efficiency and can recover energy during braking and downhill driving, improving energy utilization efficiency. Charging at night using the grid's cheap "off-peak electricity" helps balance the grid's peak and valley differences; Long charging time: Normal charging takes about 9 hours, while fast charging still requires 15 to 30 minutes; Incomplete supporting facilities: Currently, charging stations in China are as rare as phoenix feathers and hard to find. It will take a relatively long time to build the necessary supporting infrastructure.

I drive a Han EV myself, so I'm quite familiar with its slow charging time. It comes in several versions with different battery capacities, leading to varying charging durations. For example, the standard version has a 61.4 kWh battery, and using a 7 kW home charging pile, it takes about 9-10 hours to charge from empty to full. The long-range version with a 76.9 kWh battery requires around 12 hours. However, no one waits until the battery is completely drained before charging; usually starting from around 20%, it takes about 8-9 hours to reach full charge. Additionally, the ambient temperature significantly affects charging; in extremely cold winter conditions, it might take an extra hour or two. It's recommended to charge in a garage or use the scheduled charging feature to charge during off-peak hours when electricity rates are cheaper.

Charging time depends on two key factors: the vehicle's battery capacity and the charging station's power. The Han EV has different battery sizes for different configurations. For example, the 71kWh version using a 7kW slow charger with about 90% charging efficiency would take approximately 9.5 hours for a full charge. If you use a lower-power 3.5kW portable charger, it could take nearly 20 hours. Actual charging duration is also affected by the remaining battery level and ambient temperature. Starting from 50%, it could be done in half a day. If the charging station location is inconvenient, you can install a socket extension cord.

Calculating the slow charging time for the Han EV is quite straightforward. The formula is battery capacity divided by charging power. Using a standard 7kW charger, a 70kWh battery takes about 10 hours, while the 80kWh version requires just over 11 hours. However, you don't need to fully charge it every day in daily use. For example, plugging it in after work will ensure enough charge for the next day's commute. The vehicle's display screen shows estimated charging duration and remaining time, making it easy to track progress. The battery management system controls the charging pace, automatically slowing down as it nears full capacity, which is beneficial for battery health.
