What is the charging current of an electric vehicle?
2 Answers
Electric vehicle charging current is 15A. The following are the precautions for maintaining the battery of a pure electric vehicle: Regularly start the car: If the battery is not used for a long time, it will slowly discharge on its own until it becomes unusable. Therefore, the car should be started at regular intervals to charge the battery. Charge in time: When the battery level is shown to be insufficient, it should be charged promptly. The battery level can be reflected on the dashboard. Regularly check the battery: During daily driving, frequently check whether the small holes on the battery cover are ventilated. If the small holes on the battery cover are blocked, the generated hydrogen and oxygen cannot be discharged, and when the electrolyte expands, it will break the battery casing, affecting the battery's lifespan.
The charging current of electric vehicles is really intriguing. Having driven an EV for five years, I've noticed that the current varies significantly depending on the charging method. Home AC slow charging typically ranges from 10 to 16 amps, like the one in my garage with 220V voltage. The lower current means slower charging, but it's safe and cost-effective, fully charging overnight. Public DC fast charging, on the other hand, delivers much higher currents, commonly between 50 to 300 amps, replenishing most of the battery in just half an hour. However, excessively high currents can lead to battery overheating. The specific current also depends on the vehicle model. For instance, my domestic-brand EV supports up to 32A for home charging, while a Tesla can handle over 150A. In short, the current isn't a fixed value and must match the charger and battery specifications to avoid damaging the battery and wasting electricity. For daily charging, I recommend using home charging for safety, reserving fast charging for long trips to save time.
