What is the fast charging power of BYD?

BYD Tang adopts a new ternary lithium battery with total battery capacities of 19.9/23.9 (kWh). The AC slow charging power is 3.3KW, while fast charging supports 20-60KW - the higher the power, the faster the charging. Charging power: Charging power usually refers to the charging power of transmission lines, also known as reactive power. When the line is too long, there will be ground capacitance. The reactive power generated by the ground capacitance current of the line is called the line charging power. Instant charging: Timely charging when the battery level drops to the warning red bar can ensure that the EV mode won't become unavailable due to insufficient power later. Meanwhile, instant charging is beneficial for the battery - try to avoid charging only after the battery is completely depleted.
I've been driving the BYD Han EV for a while now, with a fast charging power of around 80kW, supporting DC fast charging. That time when I drove from Changsha to Shenzhen with low battery, I found a State Grid 100kW charger. Charging from 20% to 80% only took 27 minutes—it was incredibly fast! However, the actual charging speed depends on the specific power output of the charging station—some remote stations only have 40kW, so you might end up waiting for a long time. Temperature is also crucial; in summer, the system automatically reduces speed to protect the battery when it's too hot, and in winter, it needs to warm up a bit before charging normally. I recommend using a reputable charging app to check the status of charging stations in advance and ensure the plug is securely connected to prevent loosening. This makes long-distance trips much more worry-free. For daily city use, I mostly rely on home slow charging to protect the battery.
From my research on electric vehicle technology, the fast-charging power of BYD models varies by model. Mainstream models like the Qin PLUS or Tang DM-i range between 60 to 80kW, while some high-end models like the Seal support over 150kW. The power level directly determines charging efficiency—higher power can charge up to 80% in 30 minutes, but it must match the charging station's rated power; otherwise, bottlenecks occur. Real-world scenarios also require consideration of battery management: fast charging accelerates battery aging, so it's recommended to use AC slow charging regularly and reserve fast charging for long-distance emergencies. There's also room for optimization in the vehicle's onboard system and BMS software, such as displaying real-time power matching with the charging station's capability on the infotainment screen.
With over 40 years of driving experience, I can say BYD's fast charging power typically ranges between 70 to 80kW, which proves quite reliable in use. However, safety comes first—avoid charging during thunderstorms or extreme heat, and always check cables for cracks or aging. Fast charging is an emergency lifesaver, capable of filling an empty battery in just half an hour, but refrain from overusing it to avoid harming battery longevity. For daily use, a mix with home charging stations is recommended, keeping fast charging to no more than twice a month for optimal results. Before charging, ensure the port is clean to prevent sparks, and handle plug removal carefully when finished.
