Why does the electric vehicle charger keep showing a red light and not fully charge?

If the electric vehicle charger keeps showing a red light and fails to fully charge, it could be due to a damaged charger or a problem with the battery. Here are some relevant explanations about electric vehicles: 1. Charging Principle: After the light turns green, continue charging for 2-3 hours. The principle of charging is to charge frequently with shallow discharges. Charge when the battery level drops to around 50%, but avoid charging too frequently as it will shorten the battery's lifespan. If the vehicle is not used for a long time, charge it periodically (once a month). For batteries that are frequently shallow-discharged, perform a deep discharge every 3 months or so, which means discharging completely before recharging. This helps activate the inactive substances deep inside the battery. Discharging completely means until the controller's low-voltage protection is triggered. 2. Precautions: Generally, after 8-10 months of use, new batteries should be inspected and maintained. Chargers that come with well-known brand vehicles are usually pre-screened and do not require testing. However, for non-matching chargers purchased separately from the market, it is essential to test the aforementioned three parameters. There is a type of thyristor charger without a power frequency transformer that directly rectifies the mains power to charge the battery. The current can reach 30A, and the voltage is adjustable from 12V to 80V. Never touch the battery before the mains power is completely disconnected. Customers using such chargers for freight tricycles should pay special attention to safety.
