What Are the Reasons Why a Car Battery Won't Charge?
2 Answers
Introduction to the reasons why a car battery won't charge: 1. Damaged charger for the electric vehicle: Try borrowing a charger with the same type of interface to see if it can charge; 2. Damaged battery: Use a multimeter to test whether the battery's resistance is infinite; 3. Damaged battery pack: Open the battery box and measure the voltage and resistance of the battery pack. Proper maintenance methods for new energy vehicles: 1. Correctly grasp the charging time: Whether it's a new car or a new energy vehicle that has been used for a while, it's essential to understand the charging time, especially after purchasing a new car, where it's necessary to replenish the charge. During use, it's also important to correctly manage the charging time. If, during normal driving, the battery indicator shows red or yellow lights, it's time to charge to prevent over-discharge. Charging time should not be too long either, as overcharging can cause the battery to heat up and shorten its lifespan. 2. Protect the charger: The charger for new energy vehicles is also an important part that cannot be overlooked during daily maintenance. When charging a new energy vehicle, carefully read the charger's user manual. During charging, ensure the charger is well-ventilated; otherwise, it can affect the charger's lifespan and easily damage the battery. 3. Maintain sufficient power: After daily use of a new energy vehicle, it's necessary to charge it appropriately. If driving less than 20 kilometers per day, it's best to replenish the power every two days. If driving more than 50 kilometers daily, charge the same day to keep the car battery fully charged. 4. Cleaning the electric vehicle: Electric vehicles also require proper cleaning. During cleaning, be careful to prevent water from entering the charging socket inside the vehicle and ensure waterproofing measures are taken.
It's really frustrating when the battery won't charge, I've been there before. First, check if the charger clamps are securely attached – white or green powder (which is oxidation) on the metal contacts can cause poor connection. If the clamps are fine, try connecting the charger to another battery. If it charges, then the original battery is likely faulty. Aging batteries often behave this way, especially after three or four years of use, as internal plate sulfation becomes severe, making it nearly impossible to charge, like a stubborn knot. Extreme weather can also affect charging – freezing temperatures in winter or scorching heat in summer can destabilize the electrolyte, leading to charging refusal. The simplest solutions are cleaning the terminals or trying a spare charger.
