Abstract
A battery pack assembly includes a first battery cell supplying electric current to an electronic load, a second battery cell supplying electric current to the electronic load, and a first switch operatively coupled with the first battery cell and the electronic load. The first switch stops conduction of the electric current to the electronic load responsive to an increase in electric demand of the electronic load above a designated threshold. A method of powering an electronic load using a battery pack assembly also is provided.
Claims16
An assembly comprising:
- a first battery cell supplying electric current to an electronic load;
- and
- a second battery cell supplying electric current to the electronic load;
- a first switch operatively coupled with the first battery cell and the electronic load, wherein the first switch stops conduction of the electric current to the electronic load from the first battery cell responsive to a temperature of the first switch increasing above a designated threshold temperature while the second battery cell continues supplying the electric current to the electronic load.
A method comprising:
- conducting electric current from a first battery cell and from a second battery cell of a hybrid battery pack assembly to an electronic load;
- and
- stopping conduction of the electric current to the electronic load from the first battery cell responsive to a temperature of a first switch increasing above a designated threshold temperature while the second battery cell continues to conduct the electric current to the electronic load.
A powered system comprising:
- a battery pack assembly including a first battery cell and a second battery cell;
- an electronic load consuming electric current supplied by the first battery cell and the second battery cell to perform work;
- and
- a first switch operatively coupled with the first battery, the first switch switching to a blocking state to stop conduction of the electric current from the first battery cell to the electronic load and to a conducting state to conduct the electric current from the first battery cell to the electronic load,
- wherein the first switch is in the conducting state during a low demand time period of the electronic device and while a temperature of the first switch is no greater than a designated temperature threshold, the first switch in the blocking state while the temperature of the first switch exceeds the designated temperature threshold, the low demand time period occurring responsive to an electric demand of the electronic load being no greater than a designated threshold.
