At the outset, an overcharged car battery may seem like a minor issue to face since this means extra power for it to use, right? Unfortunately, this is grossly incorrect. The reality is that an overcharged battery poses several issues and could even prove to be dangerous to you and any passengers you have in your car. Usually, when your battery is continually overcharged, its lifespan will shorten dramatically, and before you know it, you will need battery replacement prematurely. In other scenarios, the overcharging causes the mixture of water and sulphuric acid in the battery to boil, which in turn heats the casing, and this will lead to swelling, melting and other physical damages. In severe cases, the battery could explode. To prevent this from happening and help you seek auto electrical repairs early, here are a few of the potential reasons why your car battery is overcharging.
The voltage regulator is damaged
New-age cars are outfitted with a voltage regulator that, as suggested by the name, will regulate the electricity that makes its way into the car battery. The voltage regulator is crucial for keeping your auto electrical system protected from undue power surges that would fry various components. Moreover, the voltage regulator ensures an even flow of voltage, and this works to inhibit a power outage when you are on the road, as this could lead to stalling and other unfortunate incidents that can cause an accident. The moment the voltage regulator acquires some damage, it loses its ability to control the amount of electricity going into the battery, and this will lead to overcharging. Seeking auto electrical repairs as soon as possible ensures this component is replaced in good time.
The temperature sensor is faulty
In addition to the voltage regulator, the temperature sensor is also tasked with regulating the amount of electricity that is reaching the car battery. It accomplished this task by monitoring how much heat is in the electrical current. The temperature sensor will take measurements continually, and these measurements are processed by your vehicle's internal computer. When the computer calculates irregular readings, it will signal this auto part so that it can limit the electrical current or leave it as-is. Thus, each time that the electrical current becomes hotter than normal, the temperature sensor kicks in. However, this component is not invulnerable to undue damages or normal wear. When it starts to become faulty, it loses its ability to give the right readings to the computer, leaving this electrical current less regulated than it is supposed to be, leading to your battery overcharging.
