Can New Energy Vehicles Not Move at 20% Battery?
2 Answers
Whether a new energy vehicle can move with 20% battery left mainly depends on the battery condition. If the battery is well-maintained, it can still operate even at 10%. However, if the battery has severe degradation, it may not move and could potentially drop from 20% to zero abruptly. Currently, mainstream new energy electric vehicle batteries on the market can be broadly categorized into lead-acid batteries, nickel-metal hydride batteries, lithium cobalt oxide batteries, lithium manganese oxide batteries, lithium iron phosphate batteries, and ternary lithium batteries (nickel cobalt manganese oxide lithium batteries). Below are the correct methods for maintaining a car battery: 1. Regular Cleaning: During daily use, pay attention to the battery's condition. Over time, the battery may accumulate dust, powder, grease, and other contaminants. To ensure normal operation, promptly clean the battery panel and the positive and negative terminals to extend its lifespan. 2. Avoid Long-Term Parking: If the vehicle is left unused for an extended period, the battery will self-discharge. Therefore, even if the car is not in regular use, it is recommended to start it once a week and take it for a short drive to keep the battery fully charged. 3. Regular Testing: The typical lifespan of a vehicle battery is 3-4 years. For high-end models with more electronic systems, the battery lifespan may be shorter. Regular testing of the battery's charge retention ensures it remains in optimal working condition.
I've been driving a new energy vehicle for several years, and from my experience, the car isn't completely immobilized at 20% battery. In fact, most new energy vehicles have intelligent protection systems that automatically reduce speed or display warnings when the battery is low, but you can still barely drive for a few dozen kilometers. However, this is quite dangerous. If you run out of power on the road, you might have to call a tow truck, which is both costly and troublesome. I recommend developing a habit: when the battery drops to 30%, start looking for a charging station. This can also help extend the battery's lifespan. In the city, it's fine since there are plenty of charging piles; but if you're in the suburbs or on a long trip, don't take the risk. Remember, frequently draining the battery can damage it, and replacing a new battery isn't cheap. My car is a domestic brand, and once it dropped to 15%, I barely managed to get home, but I never gambled on that again. During regular maintenance, check the charging system to ensure everything is working properly. Safety first—don't let that 20% become your headache.
