How many kilometers can you drive with a 10-minute fast charge?
2 Answers
Using a fast charging system for 10 minutes can typically allow you to drive approximately 5 kilometers. In principle, battery damage primarily stems from the following two aspects: 1. During battery charging and discharging: The cathode and anode of the battery shrink and expand as ions are released and absorbed. Fast charging can damage the chemical substances on the battery, leading to a shortened battery lifespan. 2. During fast charging: Due to the relatively high current, the thermal effect of the current intensifies, causing the battery to generate high temperatures. This affects the safety and stability of the battery, resulting in a sudden decrease in capacity and permanent damage to the battery cells.
When discussing how far you can drive after a 10-minute fast charge, as an EV user who pays attention to details, I believe there's no fixed answer, but a general estimate is based on charging power and energy consumption. Assuming your car supports 150kW fast charging, a 10-minute charge adds about 25 kWh (considering an actual charging efficiency of around 90%). If your car's average energy consumption is 15 kWh per 100 km, then you can drive approximately 166 km. In reality, it might be slightly less because charging speed slows down when the battery level is high before charging, and factors like low temperatures or high-speed driving also affect range. Different car models vary significantly—for example, my small household EV with a modest battery might only gain 100 km, while a high-performance car could reach 200 km. The key takeaway is not to rely too much on this number, as frequent fast charging can shorten battery life. I recommend limiting fast charging to once a week and using slow charging the rest of the time. Checking the charging station's power output before heading out can optimize your experience.
