Lithium-ion batteries are indispensable in vehicle workshops, but their high energy density harbors risks. Fire protection experts therefore provide five important tips to avoid unpleasant incidents and ensure safety in operation.
Why is it so important to handle lithium-ion batteries correctly?
In automotive workshops, lithium-ion batteries are used in many devices - from portable lamps and drills to impact wrenches or e-bikes for customers. Many of these devices are designed for outdoor use and are used in a variety of weather conditions. In addition, batteries are often not always treated properly in the hectic everyday life of a workshop.
Although the high energy density of the batteries ensures efficient performance, it also harbors risks. This is because lithium reacts with oxygen - if a battery is damaged or defective, it can release large amounts of energy in a short space of time. In the worst case scenario, this can lead to fires or even explosions. To avoid such accidents, workshops should observe the following safety measures:
The 5 most important safety tips for handling lithium-ion batteries
Tip 1: Safe storage
- Lithium-ion batteries should be stored in well-ventilated, cool rooms with temperatures between 15 and 25 °C.
- A minimum distance of 2.5 meters from flammable materials is recommended.
- Special battery charging cabinets in different sizes can help to minimize the risk of fire.
Tip 2: Safe charging
- Batteries should only be charged using chargers recommended by the manufacturer or tested by specialists.
- The charging process should be supervised in order to identify potential problems at an early stage.
- The charging area must be well ventilated and free of flammable materials to prevent overheating and short circuits.
- If a battery becomes noticeably hot during charging, it should be replaced.
Tip 3: Regular maintenance and inspection
- Batteries should be checked regularly for visible damage such as cracks or other external damage.
- Heavy batteries, for example in vehicles, should be protected from mechanical stress such as knocks or falls.
- For longer storage, a charge of 50 to 70 % is recommended to avoid deep discharge or overcharging.
- Regular inspection extends the service life of the batteries and increases safety.
Tip 4: Environmentally friendly disposal
- Lithium-ion batteries must not be disposed of with normal household waste.
- Car workshops should take old batteries to special collection points or use the take-back offers from dealers.
- Improper disposal can cause considerable environmental damage and result in criminal prosecution.
Tip 5: Safe transportation
- Special battery bags offer additional protection against moisture, shocks and corrosion on the electrical contacts during transportation.
- They are particularly practical for transportation and can protect the surrounding area from damage in the event of a battery fire.
