Abstract
A battery pack comprises a protection circuit adapted to detect an excessive current consumption condition associated with electronic components forming the battery pack.
Claims38
A battery pack, comprising:
- a protection circuit adapted to distinguish between current flow associated with a host device and current consumption associated with electronic components forming the battery pack and detect an excessive current consumption condition associated with the electronic components forming the battery pack.
A battery pack, comprising:
- at least one battery cell means coupled to electronic components forming the battery pack;
- and
- means for separately identifying current consumption by the electronic components and detecting an excessive current consumption condition associated with the electronic components.
A battery pack, comprising:
- a battery core pack coupled to electronic components forming the battery pack;
- and
- an integrated circuit adapted to compare potentials across at least two different current sensors to detect an excessive current consumption condition associated with the electronic components.
A battery pack, comprising:
- a battery core pack connected to a positive terminal of the battery pack and a negative terminal of the battery pack, the positive and negative terminals adapted to be connected to a host device;
- and
- a protection circuit adapted to distinguish between current consumption associated with electronic components coupled to the battery core pack and forming the battery pack and current flow associated with the host device to determine whether an excessive current consumption condition exists associated with the electronic components of the battery pack.
