What are the solutions for battery malfunctions in new energy vehicles during cold weather?

[DeEsther]

New energy vehicles experiencing battery malfunctions in cold weather can be addressed through the following solutions: 1. Use a multimeter to measure whether the battery terminal voltage is normal; 2. Check if the battery wiring is loose; 3. Replace the battery. New energy vehicles refer to vehicles whose power source does not solely rely on internal combustion engines. Their characteristics include: using electric motors to provide power, with the power supply for the motors being batteries, and the methods of charging the batteries including built-in generators, external charging ports, solar energy, chemical energy, and nuclear energy. New energy vehicles consist of power batteries, vehicle chassis, body, and vehicle electrical components. As an important part of electric vehicles, power batteries are divided into battery modules, battery management systems, thermal management systems, and electrical and mechanical systems.

I've been driving a new energy vehicle for several years, and the battery issues in low winter temperatures are a real headache, with range dropping like a slide. My solution is quite simple: 20 minutes before leaving every morning, I use a mobile app to activate the battery preheating function, which automatically warms up the battery, essentially giving the car a warm-up. Avoid charging in sub-zero conditions—I always charge in the garage or find a sheltered spot; slow charging is more reliable and reduces instant damage. During daily driving, gently press the accelerator for a smooth start to avoid sudden acceleration adding strain. Also, don’t let the battery drop below 30%; keeping it at least half full in winter is more stable. Regular check-ups at the 4S shop for battery health, like voltage and connector issues, are a must. After adopting these habits, my car runs steadily even in freezing winds, with no more unexpected hiccups.

Battery issues with new energy vehicles in cold weather are quite common. I've thought about solutions: first, optimize charging habits by choosing warm periods like midday for charging, or directly charging in an indoor garage to reduce temperature differential impacts. Utilize the vehicle's preheating function by activating it 10 minutes in advance to enhance battery efficiency. Maintain steady speeds while driving, and minimize the use of air conditioning and heating to conserve energy; charge promptly after parking to avoid deep discharge. If issues like failure to start occur, gently start the vehicle multiple times to allow the system to self-check, or inspect for loose fuses. Additionally, develop a habit of regular maintenance, testing battery performance and updating software before winter. It's advisable to add insulation accessories like battery covers for enhanced protection. These minor adjustments significantly improve the winter experience.

As a car owner, what I fear most in winter is the 'ghostly' behavior of new energy vehicle batteries. The solution is simple: park indoors to avoid the wind; preheat for 5 minutes before charging, letting the system control it for peace of mind. Keep the battery level above 40%, and don’t risk driving long distances with low charge. After starting the car, don’t rush—let it warm up for 2-3 minutes first. Regularly check the app data to monitor battery status changes. Address issues promptly; don’t wait until it’s frozen and hard to handle.
