Do Electric Vehicles Have Batteries?
2 Answers
Electric vehicles do not have batteries; their power comes from the vehicle's battery pack. Here are specific details about electric vehicle batteries: 1. Battery Capacity: Models with a range of over 400 kilometers typically have a battery capacity of more than 60kWh, while mainstream new energy vehicles with a range of around 300 kilometers usually have a battery capacity of about 40kWh. 2. Battery Types: Currently, almost all new energy vehicles on the market use lithium-ion batteries. However, depending on the cathode material, lithium-ion batteries are further divided into two types: lithium iron phosphate batteries, which use lithium iron phosphate as the cathode material, and ternary lithium batteries, which use lithium nickel cobalt manganese oxide or lithium nickel cobalt aluminum oxide as the cathode material.
Yes, electric vehicles do have a battery, but it's different from the one in traditional cars. I've encountered this issue frequently while repairing cars in recent years. The main battery in an EV powers the electric motor and is typically a large lithium-ion unit. However, there's also a smaller 12-volt battery hidden in the vehicle, specifically responsible for powering the electronic control units, lights, and infotainment system. This small battery activates when starting the vehicle to ensure everything operates safely. If it fails, even with a fully charged main battery, you might not be able to unlock the doors or start the screen. Therefore, regular checks on this small battery are quite important. I'd recommend owners have technicians test its voltage during every maintenance service to avoid unexpected issues on the road.
