If the Tang is charged at home using a socket, it generally takes about 12 hours to fully charge; if a charging pile is used, it takes approximately 5 hours to fully charge. When purchasing the car, the 4S store will provide a 1.6KW portable charger. For the BYD Tang, assuming a full charge requires 18 kWh, the charging time using this 1.6KW portable charger is 18kWh/1.6kW=11.25 hours. Below is an extended introduction: The BYD Tang is a plug-in hybrid electric vehicle. The characteristic of plug-in hybrids is that they can charge the battery through the engine while driving or by plugging into an external power source. There are three charging methods: 1. Home single-phase AC charging; 2. Wall-mounted charging box single-phase AC charging; 3. Charging pile single-phase AC charging.

My family owns a Tang DM-i, so I'm very familiar with home charging situations. If you use a standard 220V wall socket with the included charging cable, the power output is about 2 kW. The Tang DM-i has a 21.5 kWh battery, which means it takes over 10 hours for a full charge. Once when I started charging from empty at 7 AM, it wasn't fully charged until after 5 PM. If you drive during the day and the battery drops to 25%, charging for 7-8 hours overnight will usually top it up. However, charging is slower in winter, often requiring an extra hour or so. If you charge this way regularly, remember to check the socket temperature - older wiring can overheat and become unsafe.

As a hybrid vehicle owner, I often research charging. The charging time for the Tang depends on the specific model. For example, the Tang DM-i uses a 220V home slow charger with a power of about 2.2kW, and the 21kWh pack takes roughly 10 hours. For the new Tang EV long-range version with a 90+kWh battery, the same socket would take two days! My neighbor faced this situation and eventually installed a 7kW charging station. For daily use, it's recommended to charge when the battery level drops to 30% to avoid starting from zero each time. During charging, the vehicle's screen displays an estimated time, but the actual time is about 15% longer due to line loss and temperature effects. Socket charging is best suited for overnight charging, ensuring a full battery before heading out.

Last week, I helped a friend test his 2023 Tang DM-p. Using the portable charger, it took 9 hours and 40 minutes to charge from 15% to full. The charging time varies significantly: in summer high temperatures, the charging speed is automatically reduced to protect the , increasing the time by 20%; if you use the air conditioning or other in-car electrical devices while charging, it takes even longer. In fact, BYD has a feature that is often overlooked—the battery preheating function. In northern winters, remotely activating preheating in advance can shorten charging time by half an hour. The biggest issue with socket charging is power limitations, as a standard socket can handle a maximum of 3kW. It's recommended to check the charging plug monthly for oxidation or blackening.

Having researched new energy vehicle charging for over five years, the Tang series' socket charging requires differentiated approaches. The plug-in hybrid version has a smaller and can be fully charged in 9-11 hours using a 220V socket; whereas the pure electric version like the Tang EV would take over 40 hours with the same socket, which is practically unrealistic. Actual tests reveal that charging efficiency decreases over time: the first 80% of battery capacity charges relatively quickly, while the final 20% slows down to protect the battery, accounting for 30% of the total charging duration. Voltage stability is also crucial – during peak hours in residential areas, I've measured charging power dropping to 1.8kW, adding 2 extra hours compared to normal conditions. For hybrid owners, I recommend preparing a 16A converter plug, which charges 20% faster than standard 10A sockets.

I often get asked about socket charging by fellow car enthusiasts, and I've summarized a few key points: First, check the capacity—the Tang DM-i takes about 10 hours, while the Tang EV exceeds 40 hours. Second, pay attention to the ambient temperature; charging is fastest at 25°C and may extend by 30% in sub-zero conditions. Third, consider the charging protection mechanism—when the battery level is below 5%, it starts with a small current for slow charging to protect the battery cells. I once recorded the entire process, and the charging efficiency fluctuated between 85% and 92%. Another practical tip: if using an extension cord, always choose copper wire with a cross-section of at least 4 square millimeters; otherwise, severe overheating can actually slow down the process. Regularly cleaning dust from the charging port can also improve contact efficiency.
