The battery is one of the most expensive parts of an electric car (EV) today. So, safety is the first thing companies think about. Porsche and Audi made mistakes in this area in the past few months, leading to a recall to fix the problem. Elektrek says the recall applies to the 2023 Porsche Taycan and Audi e-Tron GT cars. The battery’s seal is a problem because it could let water in, which could be dangerous. Because liquid getting into the battery in these situations could damage it, cars with this problem may show a warning sign. The vehicles in question were made from September 23, 2022, to August 25, 2023. The companies say that 3 percent of the recalled Taycan and e-Tron GT cars will have water get into them. There are 4,777 Taycans and 1,899 e-Tron GTs that are affected by the recall. When the liquid gets into an electric car’s battery, it’s a big problem. It could cause an internal spark and a “thermal event,” which could cause the battery to get too hot or even start a fire. Also, it could cause the parts inside the battery to rust, which could cause damage over time. The problem was found for the first time in 2022 when Porsche and Audi reported a few cases in which lower insulation resistance readings showed liquid had gotten into some vehicles’ batteries. The company that makes batteries, Draxlmaier Group, came out with a new Teroson brand sealant in September of last year to strengthen the seal on the batteries. Still, the situation was being looked at and watched. Several OEM reports were made about cars with Teroson sealant that had liquid get into the battery. In the affected vehicles, moisture from the battery lowered the insulation’s resistance value, which caused dashboard warnings. When the storms of broken cars were looked at in the shop, the liquid was often found inside them. Luckily, none of the vehicles caught fire or got too hot. In May of this year, Teroson came out with a better sealer. So far, this sealer has shown that it can stop liquid from getting in. But some cars made after this date will still use batteries made with the old Teroson protection, which must meet the company’s fundamental goals. Porsche and Audi will check the cars in question for leaks to see if any liquid gets into the battery. If the tests show that there might be a leak, a new battery with an improved Teroson cover will be put in its place. All affected cars are still covered by their new car warranties, so repairs will be done for free. The car companies plan to let owners know by October 31. Even though closing a battery may seem easy, it can be hard to do it right when making something. The proper sealing materials must be chosen, put on perfectly, and given the right amount of time to harden. Every item that leaves the plant must go through this process. This could be tens or hundreds of thousands of items. Automakers usually get it right, but when they don’t, the recall system takes over.
