How to Maintain Electric Vehicle Batteries?

Maintenance measures and precautions for automotive batteries are as follows: 1. Keep the battery clean and dry at all times, ensuring the vent holes are unobstructed. If oxides appear on the plates or terminals, clean them off and apply a small amount of grease to prevent corrosion. 2. Avoid continuous use of the starter motor. Each use should not exceed 5 seconds, with a rest period of 10-15 seconds between two starts. In severe winter, the battery discharge level should not exceed 25%, and in summer, it should not exceed 50%. 3. Batteries filled with electrolyte should not be left unused for long periods without sufficient charging. Regular charging is necessary; otherwise, it may lead to battery failure. 4. When charging the battery, ensure the voltage is neither too low nor too high. Generally, the standard charging voltage for a 12V battery is within the range of (13.5~14.5)V, and for a 24V battery, it is within (28~29.9)V. 5. The electrolyte level should be (10~15)mm above the plates. If the level is too low, promptly replenish it with distilled water—do not add more electrolyte. If distilled water is unavailable, rainwater or snowmelt can be used as a substitute. Avoid using river water or tap water.
Maintaining an electric vehicle's battery, I believe daily habits are most important. I prefer using slow charging over fast charging, as frequent fast charging can overheat the battery and damage its lifespan. When charging, I keep the battery level between 20% and 80%, avoiding full charges or letting it drain completely for too long. Temperature control is crucial—I park in shaded areas during summer to prevent heat damage and preheat the car before driving in winter. Smooth acceleration while driving is key, avoiding hard presses on the accelerator or sudden braking to reduce stress from high-current discharge. Additionally, I regularly check the battery health report via the car's infotainment system and install software updates promptly to optimize performance. Occasionally, I visit the dealership for a professional inspection to ensure connectors and the cooling system are functioning properly—these small steps can significantly extend battery life. Remember, good habits save both hassle and money.
