What causes the battery charging indicator light to flicker between red and green?
2 Answers
Electric vehicle charging plug or charging port has poor contact. Below is relevant information about the battery: 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. Precautions: Batteries are most vulnerable to low temperatures. In cold environments, a battery's capacity is significantly lower than at room temperature. Therefore, timely inspection and maintenance are essential. In daily life, avoid parking the car in open parking lots for extended periods. If long-term parking is necessary, remove and take the battery with you to prevent freezing and damage.
I recently encountered a similar situation where the charging indicator light kept flickering between red and green, which was quite annoying. It's mainly caused by unstable charging. For example, when the battery itself has issues, such as increased internal resistance or a short circuit, it leads to voltage fluctuations, causing the charger to toggle between charging and fully charged states. Another reason could be a faulty charger, such as poor relay contact or aged circuits, resulting in imprecise control. Poor connection in the wiring can also trigger this problem—loose plugs or dirt affecting current transmission. Additionally, significant temperature changes in the battery might interfere with the charger's judgment, especially in extreme environments. In short, this phenomenon indicates an unstable charging path. It's advisable to first check if the plugs and wiring are secure, then test whether the charger is functioning properly. It's best to replace it or consult a professional to prevent battery damage. Ignoring such minor issues may burden the entire system, so fixing it early saves trouble.
