What is the voltage of an electric car?
2 Answers
Electric vehicles generally have a voltage of 336V or 384V, while electric buses typically operate at 580-600V. Classification of batteries: Electric vehicle batteries are divided into two main categories: storage batteries and fuel cells. Storage batteries are suitable for pure electric vehicles, while fuel cells are specifically designed for fuel cell electric vehicles. Precautions for using batteries: Avoid storing batteries in a discharged state. A discharged state refers to when a battery is not charged promptly after use, leading to insufficient charging and reduced battery capacity. The longer a battery remains idle in a discharged state, the more severe the damage. When a battery is not in use, it should be charged once a month to extend its lifespan.
As a frequent electric car owner, I find this voltage issue quite interesting. The voltage we usually refer to for electric cars is the battery pack voltage. My car is on a 400V platform, and when fully charged, the dashboard shows around 398V. But the other day, a friend who drives a Porsche Taycan mentioned his car has an 800V system, and indeed, it charges much faster than mine. Actually, charging station voltages vary too. The 7kW slow charger I installed at home uses 220V AC, while those superchargers at shopping malls can deliver 500V or even 750V DC. There's also a small 12V battery in the car that powers accessories like lights and screens, just like the small battery in a fuel-powered car.
