Why is lead acid battery used instead of Lithium-ion battery in Tata Tiago EV and other EV vehicles?

91Wheels Expert • 3 month ago
Despite the fact that lithium-ion batteries are more frequently seen in contemporary electric automobiles, lead-acid batteries are utilized in the Tata Tigor EV for a few main causes. In general, lead-acid batteries are less expensive than lithium-ion batteries, particularly for inexpensive or entry-level electric cars like the Tata Tigor EV. This lowers the cost of the car as a whole. Lead-acid battery technology has a long history of use in conventional automobiles and is well-established and tested. Lead-acid battery supply networks and manufacturing procedures are more established and dependable. For the same energy capacity, lead-acid batteries weigh more than lithium-ion batteries. The Tigor EV is a little car, though, so the weight and packing limitations might not be as important as they are for larger EVs. Comparing lead-acid batteries to lithium-ion packs, lead-acid batteries are typically less expensive and easier to maintain. Customers on a tight budget may benefit from this. Regarding the possibility of thermal runaway and fire, lead-acid batteries are thought to be safer than lithium-ion batteries, which is crucial information for a mass-market EV. But it's important to remember that, in comparison to EVs employing more sophisticated lithium-ion battery packs, the Tigor EV's performance and range are also restricted by its usage of lead-acid batteries. However, Tata Motors may have made a wise decision in using lead-acid batteries for an entry-level EV that is reasonably priced and aimed for city commuters.
