How do electric car batteries work? Where internal combustion engined cars get energy from burning petrol or diesel, an electric vehicle gets its power directly from a big pack of batteries. These are much like a scaled up version of the lithium-ion (Li-ion) battery in your mobile phone - EVs don't use a single battery like a phone, they use instead a pack which is comprised of thousands of individual Li-ion cells working together. When the car's charging up, electricity is used to make chemical changes inside its batteries. When it's on the road, these changes are reversed to produce electricity.
Electric car battery Electric car batteries are the driving force of modern EVs, built to store energy efficiently and deliver power when it’s needed. Their capacity, measured in kilowatt-hours (kWh), determines how far your vehicle can travel on a single charge.

Take the OMODA E5, for example. With a 61 kWh battery, it offers an impressive range of up to 257 miles. Similarly, the Hyundai Kona battery is engineered for reliability, delivering outstanding performance whether you’re navigating city streets or taking on longer journeys.

Designed for durability, EV batteries are backed by generous warranties, giving you peace of mind. Their modular construction also means repairs or replacements are straightforward, ensuring practicality and convenience.

By blending advanced technology with sustainable innovation, electric car batteries are a cornerstone in the move towards greener, more efficient mobility. They’re not just powering vehicles – they’re powering a cleaner future.
Lithium-ion batteries Lithium-ion batteries are the benchmark for electric vehicles, offering a lightweight design, high energy density and outstanding performance. Each battery is made up of four key components: a cathode, an anode, an electrolyte and a separator. The cathode, often crafted from aluminium coated with lithium compounds like lithium iron phosphate (LiFePO4), stores lithium ions. The anode, made from copper and coated with graphite, works with the cathode to enable energy flow. This design ensures efficient energy storage and release, making these batteries perfect for powering electric vehicles.

Their modular structure allows lithium-ion batteries to be adapted for different vehicle models. Capacities range from 40 kWh for compact EVs to 100 kWh for premium models. For example, the Polestar 2’s 69 kWh battery offers a range of 313 to 406 miles, showcasing how capacity influences energy storage, range and charging time. Larger batteries support longer journeys but may take more time to recharge fully.

Lithium-ion technology also enables rapid charging, with many EVs achieving a 10% to 80% charge time of under an hour using fast-charging connectors. This makes them highly practical for daily use. Built to last, these batteries have a lifespan of 10 to 20 years, capable of enduring thousands of charge-discharge cycles before significant capacity loss occurs.

Another significant benefit is their reduced environmental impact compared to traditional lead-acid batteries. Fully sealed to prevent harmful leaks, lithium-ion batteries use recyclable materials like cobalt, nickel and lithium, making them a more sustainable choice.

As the backbone of electric vehicles, lithium-ion batteries are driving innovation in mobility, ensuring cleaner, more reliable and efficient transportation solutions. Their combination of safety, durability and eco-friendliness cements their role in shaping the future of transportation.
