Abstract
For a battery system including a battery pack and a battery management system, the battery system having output battery terminals, a method and apparatus for preventing inadvertent connection and disconnection the output battery terminals from the battery pack is disclosed.
Claims14
For a battery system including a battery pack and a battery management system, the battery system having output battery terminals, a method of disconnecting the output battery terminals from the battery pack comprising:
- inputing a first input command to the battery management system to initiate a first time window for a first period of time, wherein the first period of time has a duration under control of the battery management system;
- maintaining the first input command until completion of the first time window to initiate a second time window for a second period of time, wherein the second period of time has a duration under control of the battery management system;
- inputing a second input command to the battery management system during the second period of time;
- and
- disconnecting the output battery terminals from the battery pack only if the second input command occurs during the second period of time.
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;
- a contactor disposed between the battery pack and the battery terminals for alternately providing an open and a closed electrical connection between the battery pack and the battery terminals, the contactor operably coupled to and under control of the central processing unit;
- and
- a user input device coupled to an input to the central processing unit;
- wherein:
- in response to a first actuation of the user input device, the central processing unit initiates a first time window having a duration for a first period of time,
- in response to continued actuation of the user input device for the duration of the first time window, the central processing unit initiates a second time window having a duration for a second period of time, and
- in response to a second actuation of the user input device during the second time window, the central processing unit operates the contactor to alternate the state of the battery system from one of the connected and disconnected states to the other of the connected and disconnected states.
