Is it normal for an electric vehicle charger to keep flashing red?
2 Answers
An electric vehicle charger flashing on and off may occur due to the following reasons: 1. The charger's converter is damaged and cannot convert or charge, requiring replacement of the charger's resistor. 2. The battery has a loose connection, which can be checked with a multimeter. 3. The charger's fuse is blown and needs replacement. 4. The power cord is detached or has poor contact at the battery socket, requiring inspection and replacement. Relevant information about car batteries is as follows: 1. Introduction: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, the term 'battery' refers to a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Working principle: It uses a lead plate filled with sponge-like lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and a 22-28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.
My electric car had the same issue before, with the charger's red light flashing, which was quite unsettling. I quickly checked the manual, and a flashing red light usually indicates a charging problem. It could be that the power socket isn't plugged in securely, or there's dust in the interface between the charging gun and the car. I've also encountered a situation where the charging gun wasn't fully locked during rainy weather, allowing moisture to get in. Last time, the repair technician told me that the battery temperature being too high or too low could also trigger the protection mechanism—I've seen the red light come on when charging outdoors in winter. If the red light keeps flashing even after repeatedly unplugging and reinserting the charging gun, it's likely a fault with the onboard charger or the charging station, and you should contact after-sales service immediately. Once, a neighbor's electric car caught fire due to a charging malfunction, so this is definitely not something to delay.
