Can a 60v electric vehicle use a 48v battery?
2 Answers
60v electric vehicles can use 48v batteries. A 60v electric vehicle is composed of 5 batteries connected in series, and its motor controller, tires, and brakes are all different. The configuration of a 60v electric vehicle is relatively higher. Introduction to automotive batteries: Automotive batteries, also known as storage batteries, are a type of battery. Their working principle is to convert chemical energy into electrical energy. Typically, the batteries people refer to are lead-acid batteries. These are mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. Working principle of automotive batteries: They use lead plates filled with spongy lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and a 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.
I think it's best not to replace a 60V electric vehicle battery with a 48V one, as it may cause insufficient power or system damage. The 60V system was designed with precise voltage calculations in mind. Although a 12V difference might seem minor, it actually leads to unbalanced current distribution, resulting in poor vehicle performance, slow acceleration, and difficulty climbing hills. I made a similar mistake by trying an old battery, and after a few starts, the vehicle flashed a red light and shut down. It turned out the controller detected low voltage and entered protection mode, blowing a fuse and nearly damaging the motor. In the end, I spent twice as much on repairs. My advice is to stick with a properly matched 60V battery and not cut corners for the sake of saving money. From a safety perspective, it's not worth the risk—voltage mismatch can cause short circuits and fires, especially in rainy conditions, which is even more dangerous.
