How much battery power is there in an electric car?

OK, so I’m confused. Gas-powered cars have a battery, but so do electric cars. Yet, electric cars don’t need an engine. So in order to make up for not having an engine, how much battery power is there in an electric car?

I totally get it! Wrapping your mind around the way electric vehicles are constructed is a whole different ball game. Internal combustion cars have a battery that starts the engine, and powers up electrical functions like the windows and radio.
And like you mentioned, electric cars also have an internal battery. They usually sport a 12-volt lead-acid battery and have a rechargeable battery pack that can be used to power the motor. And don’t even get me started on how awesome regenerative braking is. We’re talking about reusing 70% of your car’s energy that would otherwise be lost!
Here’s what we know about the battery power in an electric car:
  • There are two common types of electric car batteries. ** Lithium-ion batteries** are used more often, especially in vehicles that are all-electric.** Nickel-metal hydride batteries **have a high self-discharge rate and don’t charge as fast.
  • The battery capacity in electric vehicles is measured in kilowatt-hours (kWh). It’s actually the same unit that determines your electric bill at home. The bigger the kWh number, the better the range of your electric car.
  • The kWh measurement varies by vehicle. A 2021 Nissan Leaf 40 kWh battery, while a Tesla Model S has a 100 kWh battery. The Tesla gets about 250 more miles of range than the Leaf.
  • Electric cars aren’t able to fully use the rated capacity of their car battery, and unfortunately, the usable capacity number is not something carmakers typically provide. On average, you should be able to work with 60 to 70% of the listed capacity.
You can extend your electric car battery’s life by avoiding DC charging stations, avoiding extreme temperatures, and keeping your car charged between 50 and 90%.
Now that you’re up to speed on how the battery pack functions on an electric car, make sure you’re also up to date with the latest car insurance trends. Did you know most Americans _overpay _for their car insurance every month?
