BATTERY PACK WITH SAFETY DEVICE, CONTROL DEVICE AND CONTROL METHOD
First Claim
1. A battery pack (1, 33) comprising at least one battery cell (3, 39), and being designed to supply an output voltage for feeding electric energy to a load (23) so that the load may perform a function, the battery pack further comprising a battery control circuit (11, 41, 43) connected with at least one battery cell and arranged to be able to avoid feeding the voltage supplied by the at least one battery cell through the battery control circuit, characterized in that the battery control circuit (11, 41, 43) is adapted to receive an operate control signal indicating that the load (23) is to perform its function, and to allow feeding the supply of voltage through the battery control circuit (11,41,43) in response to the operate control signal.

Abstract
A battery pack (33) includes at least one battery cell (39), and is designed to supply an output voltage for feeding electric energy to a load (23) so that the load may perform a function. A battery control device (35) arranged to generate control signals for controlling a battery pack, a device (21) including a battery pack, and a method for controlling a battery pack are also described.

- 9. A battery control device arranged to generate control signals for controlling a battery pack (1, 33), which battery pack comprises at least one battery cell (3, 39) and is arranged to supply an output voltage for feeding electric energy to a load (23) so that the load may perform a function, characterized in that the battery control device (35) is arranged to generate an operate control signal to the battery pack (1, 33) in response to receiving information that the load is to perform its function, which operate control signal induces a battery control circuit (11, 41, 43) connected with at least one battery cell in the battery pack to allow feeding a supplied voltage from the battery cell through the battery control circuit (11,41,43).

16. A method of supplying electric energy to a load in order for the load to perform a function, the method comprising
receiving information that the load is to perform its function, generating an operate control signal in a battery control device, receiving the operate control signal in a battery pack comprising at least one battery cell arranged to supply a voltage to the load, and allowing feeding the supply of voltage through a battery control circuit in response to the operate control signal.
