Electric vehicles offer tons of benefits for the modern Watkinsville driver, including emissions-free performance and fantastic reliability. But since EV technology is still new to many shoppers around Jefferson and Greensboro, we often get questions about the types of batteries used in electric vehicles. How do electric vehicle batteries differ from gas-powered designs? How do electric car batteries compare to hybrid models? Learn all about the types of batteries used in electric vehicles, and continue your BMW research with Athens BMW.
Electric car batteries are larger than traditional automotive batteries, and they have a much longer lifespan as well. But there are four main types of an electric car battery that you’ll find under the hood of models like the BMW i4 and iX:
Nickel-Metal Hydride batteries — While you’ll find some EV models with NiHM batteries under the hood, this type of battery is most commonly used in hybrids. That’s because the NiHM battery is not quite as effective as other options on the market. However, it has a much longer lifespan than many alternatives – making it the perfect choice for a hybrid.
Ultracapacitor batteries — These are not considered traditional batteries, but you’ll find them used as a secondary storage device in electric vehicles. Ultracapacitor batteries help electrochemical batteries level their load, bringing in extra power when accelerating and regenerating braking.
Lead-acid batteries — Lead-acid batteries are used as supplemental EV batteries because they are inexpensive, safe, reliable, and high-powered. They are generally not the primary battery due to their shorter lifespan and poor cold-weather performance, but their high-powered nature makes them a perfect choice to support other battery loads.
Lithium-ion batteries — Lithium-ion batteries are the most common type of electric car battery due to their well-rounded performance. They have numerous advantages over other options: high power-to-weight ratio, excellent performance in any temperature, and high energy efficiency. And because they have a lower “self-discharge” rate, they hold a charge for longer than other battery types.
