![]() ![]() Like lead-acid batteries, ultracapacitors are used as secondary storage devices and help to level the load of lithium-ion battery packs. This sort of battery is only used in EVs to power supplemental auxiliary features providing backup power to power steering, brake boosting, and to power the safety features in EVs. However, lead-acid batteries have a relatively short life, and don’t do well in cold weather. They have been around a long time and are inexpensive and safe to use. These are the kind of 12-volt batteries used in gasoline-powered cars to start the motor. ![]() The drawbacks are that they are expensive to produce, generate a lot of heat at high temperatures, and have a high discharge rate. Nickel-metal hydride batteries generally last longer than lithium-ion batteries and are safe to use. These cars use gasoline power to recharge the onboard battery. ![]() You’ll mostly find these battery packs in hybrid vehicles that combine a gasoline engine with electric motors. For instance, it takes 500,000 gallons of water to refine one ton of lithium. However, lithium-ion batteries have come under a lot of scrutiny for the not so eco-friendly way the materials for them are mined. Very efficient and offering excellent high-temperature performance, they are currently the best option for holding a stable charge and are recyclable. It is the same technology used in smartphones and laptop computers and are known for having a high power-to-weight ratio. Most of today’s EVs use lithium-ion battery packs. ![]()
