Why does the lithium electric car suddenly lose power but regain it after re-plugging?
2 Answers
Lithium electric car suddenly losing power but regaining it after re-plugging may indicate battery damage, and immediate repair is recommended. Causes of car battery damage: Continued operation of the cigarette lighter after turning off the engine; not turning off multimedia or air conditioning systems before shutting down the engine; prolonged use of electricity after turning off the engine; frequent or prolonged ignition attempts. Battery maintenance methods: Avoid storing the battery in a depleted state. A depleted state refers to the battery not being charged promptly after use, which can lead to sulfation. Lead sulfate crystals form on the electrode plates, blocking ion channels and resulting in insufficient charging and reduced battery capacity. The longer the battery remains unused in a depleted state, the more severe the damage. When the battery is not in use, it should be charged once a month to extend its lifespan.
It's quite common for electric vehicles to suddenly lose power and then regain it after re-plugging. I've pondered this issue myself while tinkering with my own vehicle. The most frequent cause is poor contact, where dust buildup or slight oxidation between the plug and socket leads to unstable connections; daily vibrations or bumps can interrupt the power, and re-plugging temporarily restores the connection. It could also be the battery's internal protection circuit kicking in, such as when overheating or a sudden current surge triggers protection mode, and plugging it back in resets it. Additionally, an aging or faulty charger with unstable output can cause intermittent power supply. In the long run, ignoring this issue can lead to reduced battery life or potential overheating risks. I recommend regularly cleaning the charging port, checking if the plug fits snugly, and avoiding use in high-temperature environments. If possible, use a multimeter to test if the charging voltage is stable, preventing minor issues from turning into major faults early on.
