What are the reasons for the damage to new energy vehicle chargers?
2 Answers
Reasons for damage to new energy vehicle chargers: 1. Automatic charging after power restoration. 2. Pressing the charging connection device switch stops charging. 3. Excessive temperature of the power battery. 4. Malfunction of the vehicle or charging pile. Additional information: Precautions for charging new energy vehicles: 1. When storing the vehicle unused for a long time, first charge it to 100%, then discharge it to between 25% and 40%. 2. If the storage time exceeds three months, the battery must be charged; otherwise, battery performance will degrade.
As someone who has dealt with many new energy vehicles, I've seen that charging unit failures are mainly caused by these reasons. Voltage issues are the most common: unstable power grids or significant voltage fluctuations from charging piles, such as when charging in old residential areas or industrial zones where the voltage fluctuates wildly, can cause the charging unit to overheat or even burn out. Cooling system failure is another key factor: the charging process generates a lot of heat, and if the cooling fan is clogged with dust or the heat sink is covered in oil, the heat can't dissipate, leading to accelerated aging and damage of internal components. Component aging cannot be ignored: capacitors and circuit boards degrade over time, especially with frequent fast charging, which speeds up wear. Additionally, inadequate waterproofing during rainy seasons or after car washes can lead to short circuits. It's recommended that owners choose stable power environments for charging, regularly clean the cooling vents with a vacuum, and have a professional inspection annually to prevent unexpected issues. Remember, safety first—early detection of problems can save both money and hassle.
