How Many Kilowatt-hours Does It Take to Fully Charge a New Energy Vehicle?
2 Answers
Currently, the electricity consumption of mainstream electric vehicles in China can be found online, generally exceeding 15 kWh per 100 kilometers. Precautions for charging new energy vehicles are as follows: After High-Temperature Exposure: Do not charge immediately after high-temperature exposure. Prolonged exposure to high temperatures causes the power box temperature to rise, leading to an increase in battery temperature. Charging immediately can accelerate the aging and damage of internal wiring. Avoid Charging During Thunderstorms: Do not charge during thunderstorms. When it rains with thunder, avoid charging to prevent lightning strikes, which could cause combustion accidents. Avoid Using Air Conditioning While Charging: It is not recommended to turn on the air conditioning inside the vehicle while charging. Using the air conditioning during charging increases the internal charge load on the battery, accelerates the degradation of the power battery pack, and reduces battery lifespan. Choose Standard-Compliant Charging Stations: Select charging stations that comply with national standards. This not only protects your vehicle's battery but also ensures your safety.
Back when I drove an electric car for ride-hailing, I specifically calculated the costs. Just check the car's battery capacity—for example, a car labeled with 60 kWh actually requires about 66 kWh to fully charge. Why? Because the charging process generates heat in the wires, and there's also loss at the charging station. If home charging costs 0.6 RMB per kWh, a full charge would only cost around 40 RMB, saving two-thirds compared to a gas car. A key reminder: don’t drain the battery completely before charging. You should recharge when the battery level drops to 20%, otherwise, it damages the battery. Don’t follow those who charge only when the battery falls below 10%—it’s like always letting your phone die before charging. That will drastically reduce battery lifespan.
