How to Maintain Electric Vehicle Batteries?
1 Answers
Introduction to Electric Vehicle Battery Maintenance: 1. Maintenance of Electric Vehicle Appearance and Motor: The first step in electric vehicle maintenance is an exterior inspection, including checking the steering wheel, seat belts, various switches inside the vehicle, and whether the combination instrument panel is functioning normally. It also involves checking the functionality of lights and horns, the aging degree of components like wipers, tire inflation status, and any damage or wear. Electric vehicles require checking antifreeze, brake fluid, and windshield washer fluid. Electric vehicles also use antifreeze, but unlike traditional vehicles, the antifreeze is used to cool the motor and needs to be replaced according to the manufacturer's specified intervals, typically every 2 years or 40,000 kilometers. The types of antifreeze are exactly the same as those for traditional cars. Gear oil (transmission oil) is a fluid that electric vehicles need to replace more frequently, but the replacement intervals vary by manufacturer. 2. Maintenance of Electric Vehicle Battery Packs: The battery pack is the most critical part of the chassis inspection. A battery pack generally consists of about a hundred independent cells, and in case of a malfunction, professional repair by the manufacturer is usually required. During maintenance, the 4S shop will visually inspect the battery for any damage and connect to a computer to check for any fault records in the battery. Additionally, electric vehicles are equipped with an onboard terminal system that monitors the battery status and uploads data to the manufacturer's server and government servers. If the battery status is abnormal and poses a potential danger, the owner will be notified. Chassis inspection includes checking for chassis damage, deformation, loose screws, and fluid leaks.
