![]() When a high-voltage battery is damaged, it can leak fluoride gas, which is heavier than air, causing it to sink and not rise. Ventilation is very important for EV batteries there must be ventilation around the battery, including underneath it. Current National Highway Transportation Safety Administration guidelines suggest 50 feet of separation between a stored battery and a building or another vehicle. The optimal scenario would be a storage/building outside your facility that’s temperature-controlled and has a ventilation system. ![]() This consideration can get lost in the shuffle when a vehicle is “out of sight, out of mind.” It’s a good reminder to think about what’s happening under the vehicle - and to think through various temperature implications to ensure safe battery handling.Īny removed battery requires special storage. Some vehicles may sit on the lot for weeks or months waiting for parts, giving the battery the opportunity to experience swings in temperatures with likely no or few systems designed to regulate temperature. The ongoing parts shortage is a stark reality for EV repair. Case in point: Some OEMs specify complete removal of the battery, while others provide specific instructions on maximum temperature/time for painting. Battery temperature and time limits can be different from one manufacturer to the next - and even from one model to another within the same manufacturer! To help the industry with variations in temperatures, I-CAR’s Repairability Technical Support (RTS) portal will soon display a master list that describes maximum vehicle battery temperature and time compared to paint curing temperatures and times. In this case, there is no vehicle communication between the control units, and the internal temperature mechanism for the battery is not connected.įor repairers, the first and most critical step is to check the OEM guidelines, provided a battery has been properly tested to ensure there is no damage.įor bodywork that requires painting, it’s important to remember the high temperatures achieved within a paint booth, especially during the curing of the paint. When a vehicle comes in for repair, most often the battery has been disconnected (or removed) and the low-voltage system (12-volt) is disconnected. Likewise, in hot weather, the vehicle’s AC compressor cools water via a component called the “chiller,” helping to keep the battery temperature lower. In colder weather, the vehicle’s heating system kicks in, heating water which, in turn, flows to warm the battery. In normal operations, EVs are wired to fluidly maintain temps. The “sweet spot” temperature for an EV battery is approximately 70 to 75 degrees Fahrenheit. Please note: This information does not replace OEM repair procedures, which are customized for nearly every single make and model of vehicle. Let’s outline some key considerations for the proper/safe handling, storage and disposal/recycling of batteries. As the volume of EVs entering your bays will continue to increase, so too will the repair considerations you’ll need to make - most notably, the EV battery. Please contact your STIHL servicing dealer.The consensus is that EVs are here … and here to stay. Do not open batteries and never use a defective or deformed battery.If you have a backup battery, you should not store it unused, but instead alternate its use with your other battery.Charge your battery again just before you use your machine for the first time. If you store your battery for a long period, e.g., during the winter, it should be stored with an approx.There it is generally neither too warm nor too cold. Ideally, you should store the battery in your basement. ![]() For optimum service life and low self discharge, store your battery at temperatures from + 10☌ to + 20☌. ![]() Store your battery in a closed, dry space in a secure location. ![]()
