How many kilowatt-hours are needed to fully charge the Tang DM?
2 Answers
The Tang DM requires approximately 22 kilowatt-hours for a full charge. Battery capacity: The BYD Tang DM utilizes lithium iron phosphate batteries. For the 80kW version, the battery capacity is 18 kilowatt-hours. Charging time: Under maximum charging power, a full charge takes about 5 hours. However, the actual charging power of the vehicle's included charging cable is 1.5kW, which can be directly plugged into a 220V household socket. This means an average charging rate of about 1.5kWh per hour. Charging efficiency: The onboard charger's power isn't particularly high. If equipped with a 6.6kW wall-mounted charging box (charging pile), the charging efficiency would improve by about half.
I've been driving the Tang DM for almost a year now. The battery capacity is around 19 kWh when fully charged, depending on the model - for example, the newer DM-i version might go up to about 21 kWh. There's some actual charging loss, so using a home charger requires approximately 20 kWh. Home charging is convenient; usually a few hours of charging at night will fill it up, and the pure electric range of about 110 km is sufficient for commuting. The electricity cost works out to a few cents per kWh, so a full charge costs less than 20 yuan, which is much cheaper than using gasoline. There are many charging stations near my home, and it's quick to charge before a long trip on weekends. For regular maintenance, be careful not to over-discharge the battery, and always use certified charging equipment for safety. Based on my personal experience, I recommend new owners familiarize themselves with the charging operations - it's quite hassle-free.
