Abstract
A device for testing a battery, having a transport system, wherein the transport system is configured for receiving the battery, for transporting the battery to a test position, and for transporting the battery out of the test position. The device also includes an interface configured to supply the battery arranged in the test position with electric power and configured to supply the battery arranged in the test position with gas.
Claims17
A device for testing a battery,
- having a transport system, wherein the transport system is configured
- for receiving the battery,
- for transporting the battery to a test position, and
- for transporting the battery out of the test position;
- the device being configured for a simultaneous leak-tightness test and power test of the battery arranged in the test position having an interface,
- wherein the interface is configured to supply the battery arranged in the test position with electric power;
- and
- wherein the interface is configured to introduce gas into the battery arranged in the test position for the leak-tightness test of the battery,
- having a fire protection hood, which can be lowered onto the transport system, for shielding the battery from the surroundings is provided,
- wherein the fire protection hood is configured to be automatically lowered to shield the battery from the surroundings if a hazardous situation is detected, while the fire protection hood remains in a waiting position above the test position viewed in the vertical direction during testing, if test of the battery runs without errors.
7 more elements
A method for testing a battery, having the following method steps:
- providing the battery to be tested on a transport system;
- transporting the battery into a test position by the transport system;
- and
- supplying the battery to be tested with electric power and with gas via an interface for a simultaneous leak-tightness test and power test of the battery arranged in the test position,
- wherein
- a fire protection hood, which can be lowered onto the transport system, is provided for shielding the battery to be tested from the surroundings,
- wherein the interface is automatically decoupled before the lowering of the fire protection hood and/or during the lowering of the fire protection hood,
- wherein
- during and/or after the supply of the battery to be tested with electric power and/or during a discharge of the battery, a temperature of the battery to be tested is monitored, and/or a smoke development of the battery is monitored, and
- the fire protection hood for shielding the battery to be tested is lowered onto the transport system if a threshold value of the temperature and/or a threshold value of the smoke development is exceeded,
- wherein the fire protection hood, after being lowered onto the transport system, is automatically decoupled from a handling unit, which carries the fire protection hood, wherein the battery is automatically transported out of the test position after the lowering and decoupling of the fire protection hood.
