Is it serious to charge a 60V vehicle with a 72V charger?
3 Answers
Using a 72V charger to charge a 60V electric vehicle may result in incomplete charging, inability to charge, or slow charging speed. Extended information: Electric vehicle: An electric vehicle is a relatively common means of transportation. The main components of an electric vehicle include the frame, motor, battery, and controller. The controller is used to control the entire vehicle's circuit. Without the controller, the electric vehicle cannot operate normally. The motor is the power source of the electric vehicle, driving it forward. The battery is a component used to store electrical energy, supplying power to all electronic devices in the vehicle. Charging tips: When charging, connect the battery end first and then the power source to effectively prevent current surges; avoid charging under direct sunlight to prevent battery water loss; after riding home, let the electric vehicle sit for 40 minutes before charging to effectively protect the battery; if not riding for a long time, it is best to charge once every week to prevent battery discharge; avoid using fast charging, etc. By following these practices, users can also maximize the lifespan of the electric vehicle battery.
Using a 72V charger for a 60V vehicle is quite dangerous. Speaking from personal experience, a friend tried it before, and the battery overheated severely. Fortunately, it was discovered in time, avoiding a major incident. The reason lies in the excessively high voltage, which can easily lead to overcharging, increased internal pressure in the battery, accelerated aging, or even swelling and explosion. It is recommended to stop using it immediately and check the battery for any swelling or abnormal temperature. If charging has already occurred, it is advisable to visit a professional repair shop as soon as possible to test the battery's health condition. I always emphasize that the charger must match the voltage value—don’t cut corners or mix them up incorrectly. Safety first, prevention is key.
As someone who frequently deals with cars, I've encountered many similar situations. Using a 72V charger for a 60V battery creates voltage mismatch, which can cause excessive charging current, damaging the battery separator or electrolyte. The issue may not be immediately apparent, but long-term use can lead to performance degradation or short-circuit fires. The correct approach is to use a dedicated 60V charger. If the wrong charger is used accidentally, power should be disconnected immediately and the output voltage measured with a multimeter for confirmation. During repairs, it's common to see users overlook this point. In fact, safety details are crucial in daily maintenance, and developing the habit of checking equipment specifications is essential.
