What should be noted when charging an electric vehicle battery for the first time?

During the first charge, it is essential to use the original charger and start charging when the remaining battery level reaches 30%. The charging time for the first charge can be between 8 to 10 hours, with the maximum charging time not exceeding 12 hours to avoid damaging the battery. Below is relevant information: 1. Pure Electric Vehicles: Pure electric vehicles refer to vehicles powered by an onboard power source, using electric motors to drive the wheels, meeting all requirements of road traffic and safety regulations. Due to their relatively smaller environmental impact compared to traditional vehicles, their prospects are widely optimistic, although current technology is not yet mature. 2. Composition: The composition of electric vehicles includes the electric drive and control system, mechanical systems such as drive force transmission, and working devices to complete set tasks. The electric drive and control system is the core of an electric vehicle and the most significant difference from internal combustion engine vehicles. The electric drive and control system consists of the drive motor, power source, and motor speed control device, among others. Other components of electric vehicles are essentially the same as those of internal combustion engine vehicles.
I just replaced the electric vehicle's new battery and need to be extra careful during the first charge to avoid messing it up. After the battery replacement, I'll first check all wire connections to ensure they're securely fastened without any looseness or corrosion. When charging, it's essential to use the original charger—don't just grab any fast charger as a substitute. Slow charging mode is the safest to prevent initial damage to the battery cells. Temperature is also crucial: avoid charging under direct sunlight or in freezing conditions. I usually opt for indoor charging at around 20°C. The first charge should be a full charge, ideally lasting 8-12 hours to activate the battery's internal chemicals and calibrate the management system. After charging, check if the battery overheats or emits any unusual odors, as these are danger signs. Remember, the first charge of a new battery impacts its long-term lifespan, so don't cut corners for convenience.
As an average car owner, I prioritize safety. When charging the new battery for the first time after replacement, I repeatedly verify proper installation and secure wiring connections without exposed parts. I choose a well-ventilated, dry charging location, avoiding kitchens or wet areas to prevent short circuits and fires. Using the manufacturer-provided charger, I avoid fast charging initially—slow charging helps the battery adapt smoothly. I monitor the entire charging process for hours, watching for abnormalities like smoke, unusual noises, or overheating—immediately cutting power if detected. The ideal charging duration follows the manual, typically 6-8 hours. After charging, I test the electric vehicle's operation to ensure normal functionality. Properly maintained new batteries can last years longer—safety always comes first.
I prefer to keep it simple: After installing the new battery, charge it overnight in the garage or on the balcony using slow charging mode for the first time. The key is to use the original charger and avoid switching it randomly, stopping only when the battery indicator shows full. Maintain a comfortable environment during charging—neither too hot nor too cold—to prevent affecting battery activation. After charging, take a short ride to test the range and experience the new battery's performance. The whole process involves no complicated steps; the key is patiently waiting for a full charge.
