Claims16
For a battery system including a battery pack and a battery management system, the battery system having battery output terminals, a circuit for alternating the state of the battery system between a connected state, wherein the battery pack is connected to the battery output terminals, and a disconnected state, wherein the battery pack is disconnected from the battery output terminals, the circuit comprising:
- a central processing unit;
- means electrically disposed between the battery pack and the battery terminals for alternately switching the electrical connection between the battery pack and the battery terminals, between an open electrical connection and a closed electrical connection, under control of the central processing unit;
- and
- a user input device coupled to an input to the central processing unit for producing a user input command;
- wherein in response to an actuation of the user input device producing the user input command to the central processing unit, providing an indication in a first manner and initiating a first period of time defining a first time window, the indication in the first manner continuing during the first time window while the user input device remains actuated;
- wherein when the user input device has remained actuated upon completion of the first period of time, providing an indication in a second, different manner and initiating a second period of time defining a second time window, the indication in the second manner continuing in the second manner during the second time window while the user input device remains actuated;
- and
- wherein the central processing unit only operates the switching means to alternate the state of the battery system if the user input command is released during the second time window, wherein if the user input command is released during the first time window or upon completion of the second time window, the indication is provided in a third manner different than the second manner and the battery system remains in its initial state.
