How Many Days Can an Electric Vehicle Last on a Single Charge?

[MacViolet]

For a car battery, a single charge can last from half a month to a full month. Below are some relevant points about car battery usage: 1. Combined Use of Car Batteries: Since car batteries are designed for short-term, high-current discharge (start-up batteries), they are shallow-cycle types. In contrast, inverters require long-term, stable low-current discharge. Therefore, specialized energy storage batteries or traction batteries used in electric vehicles are recommended. 2. Long-Term Unused Batteries: Car batteries are lead-acid types and generally should not be left discharged. They should be kept fully charged to avoid affecting their lifespan. To check if a battery is fully charged, observe if bubbles are produced—bubbles indicate a full charge. Batteries that are unused for long periods should be charged every half month or month.
