In this case, the supply of the electric motor generally takes place via an external connection to the power supply network. Smaller soil compaction machines, which are often operated by DC motors, can also be powered by electrical energy from an energy storage such as a rechargeable battery. When operating soil compacting machines with a high power requirement through an energy store, heating of the energy store may occur and possible overshoots of the maximum permissible operating temperature of the energy store may occur. For example, can be done by high power consumption and -abgäbe a self-heating of the energy storage. Furthermore, the energy storage can be additionally heated by heating the environment, for example by a working heat of the mechanical system.
- the heating of the energy store can have various disadvantageous consequences.
- the energy storage can be permanently damaged by the high operating temperature.
- an operator of the soil compaction device can also be damaged. Possible hazards can be caused by a fire or explosion hazard of the superheated energy storage. Also, a risk of chemical burns and / or poisoning may exist on contact with chemicals of a damaged energy store.
