Abstract

An electric energy storage device has a housing, a positive pole and a negative pole, and a deep discharge device integrated in the housing. The device further has a discharge load and it is configured such that the two poles can be electrically connected by way of the discharge load. There is enabled targeted and controlled deep discharging of the energy storage device and improved operating reliability.

Claims

1. An electric energy storage device, comprising:

a housing;

a positive pole and a negative pole;

a deep discharge device integrated in said housing and having a discharge load and a manually operated switch that is switchable between a passive switch position, in which said positive and negative poles are electrically separated, and a discharge switch position, in which said positive and negative poles are electrically connected together by way of said discharge load;

a control display configured to display a state of charge of the energy storage device; and

a protective cover disposed to cover said switch, said protective cover configured such that said protective cover must be removed or destroyed in order to enable an operation of said switch, said protective cover being made of glass or plastic;

said manually activated switch attached to said housing to be accessible from outside said housing.

2. The electric energy storage device according to claim 1, wherein said switch is configured to render a switching operation from the passive switch position to the discharge switch position irreversible.

3. The electric energy storage device according to claim 1, further comprising a cooling device thermally coupled to said deep discharge load.

4. The electric energy storage device according to claim 3, wherein said cooling device includes a heat exchanging structure selected from the group consisting of heat exchanger plates and channels for receiving a cooling liquid.

5. The electric energy storage device according to claim 3, wherein said cooling device includes heat exchanger plates.

6. The electric energy storage device according to claim 3, wherein said cooling device includes channels for receiving a cooling liquid.
