A car's range depends on its battery's capacity and efficiency of use. Generally, most vehicles will need 20 to 30kW of power on highways for a steady speed.
That buffer prevents it from ever being completely charged. For example, the Audi Q8 e-tron's battery pack has a gross capacity of 114 kWh, but its usable capacity is 106 kWh. Most automakers advertise the gross capacity. Like fuel tank sizes, electric car battery pack capacities vary depending on the vehicle.
All electric car batteries have a usable capacity that's slightly less than the gross capacity because this helps extend the life of the battery pack. That buffer prevents it from ever being completely charged. For example, the Audi Q8 e-tron's battery pack has a gross capacity of 114 kWh, but its usable capacity is 106 kWh.
When we talk about “EV battery capacity” or “EV battery sizes,” we're referring to how much energy the battery can store, measured in kilowatt-hours (kWh). But why do these matter to an EV owner? Or someone considering an EV? Well, here's why: Range - generally, the larger the kWh, the further you can drive on a single charge.
In the EV world, kilowatt-hours are to batteries as gallons are to gas tanks. But a full battery can't be completely equated with a full fuel tank. All electric car batteries have a usable capacity that's slightly less than the gross capacity because this helps extend the life of the battery pack.
Most electric vehicles in the UK range from 20 kWh at the smaller end to over 100 kWh at the top end. But if you're curious about the sweet spot for the majority of drivers, 40-60 kWh is very common.
Recently announced by CATL that its batteries have a density of over 290Wh/litre for LFP chemistry and over 450Wh/litre for NCM chemistry. Power gives acceleration to the car and maintains it at a given speed. Though mechanically power is the product of torque and rpm. But in the electrical domain power is the product of voltage and current.

What is Battery Capacity? Battery capacity is the amount of energy a battery can store, typically measured in ampere-hours(Ah) or watt-hours(Wh). Ampere-hours indicate the total charge a battery can deliver at a specific current over time, while watt-hours provide insight into the energy stored, factoring in voltage. It can calculated as the
