How much can a roadside fast charger charge in 10 minutes?

[DiCody]

Charging for 10 minutes can bring the battery to 80% of its capacity, which is about 60%~70% of the range of a fully charged battery. Basically, 10 minutes of charging can achieve an effect of about 3 kilometers. Below is some related information about charging piles: 1. Current: Generally, fast chargers have a charging current of 10A, so charging for 10 minutes would be 1.666AH. Based on a vehicle driving current of 10A, it can drive for 10 minutes. At a speed of 30KM/H, it can drive about 5KM. 2. Battery: After an electric vehicle battery is discharged, passing direct current through the battery in the opposite direction of the discharge current restores its working capacity. This process is called battery charging. When charging, the positive terminal of the battery is connected to the positive terminal of the power source, and the negative terminal of the battery is connected to the negative terminal of the power source. The voltage of the charging power source must be higher than the total electromotive force of the battery. 3. Charging methods: There are two types—constant current charging and constant voltage charging.

I've tried roadside fast charging several times, and how much you can charge in 10 minutes mainly depends on the charger and your car. Common roadside fast chargers typically deliver between 120 to 250 kW. If your car supports high-voltage fast charging—say, it can handle over 150 kW—you can expect to add around 15% to 20% charge in roughly ten minutes. Based on average energy consumption, that translates to an extra 100 to 200 kilometers of range. However, this depends on the battery's condition: if it's nearly full or severely depleted, the speed drops noticeably. Cold weather also slows charging, while in summer, high temperatures may trigger the charger to limit power to prevent overheating. Once, I charged my EV at a highway service station, and in just ten minutes, the range jumped from 100 km to 300 km—astonishingly fast. But don’t rely on it too much; frequent use could shorten battery life, so reserve it for emergencies. When choosing a charging station, always check the charger’s power rating—higher-power options are more worthwhile.

When I drive long distances, I often use fast charging stations, and the 10-minute charging effect is really good. Based on my experience, the charging power generally starts at 120 kW, with high-end stations reaching up to 350 kW. My car is a mainstream electric vehicle that supports 180 kW fast charging. After plugging in for ten minutes, the screen shows an increase of over 120 km in range, with the battery level rising by about 15%. Actual test data: when the charging station power is 200 kW, the car actually accepts around 180 kW, resulting in approximately 24 kWh of electricity charged, enough for me to drive 150 km. However, performance varies at different times—charging is faster in the early morning but slower at noon when it's hot. Additionally, older car models only charge at 50 kW, delivering half the effect. I recommend checking the app to confirm the charging station's status before use to avoid wasting time on faulty stations. Fast charging is convenient, but don’t rely on it as your primary charging method—charging speed slows down as the battery ages, which can affect safety.

There's a significant difference in fast charging speeds among different vehicles at roadside stations. For instance, my older electric vehicle only supports up to 50 kW, so ten minutes might only add 5% charge, extending the range by 30-40 kilometers—hardly enough for a drive. Switching to newer models like BYD or Tesla, which support over 250 kW, the same ten minutes can add 15% to 25% charge, equivalent to over 150 kilometers of range. The key factor is the vehicle's maximum charging power rating; newer cars have more advanced batteries, better thermal management, and higher efficiency. Charging stations also vary in power—highway exits often offer 120 kW, while urban centers can reach 350 kW. When I tried a friend's car, the fast-charging icon appeared with higher-power stations, showing a substantial boost in charge. For daily use, slow charging is better for battery health, while fast charging is ideal for emergencies.
