Abstract
A portable battery pack containing multiple battery stacks operable to deliver power to equipment with differing power requirements that may further be compact and easily maintained. Further, the battery pack may have an integrated battery management system and charger system to prevent over-discharge and/or overcharging of the battery cells contained therein.
Claims20
A battery pack comprising:
- a first plurality of individual battery cells arranged into a first battery stack having a first voltage rating in operative communication with a first output, the first output having the same voltage rating as the first battery stack;
- a second plurality of individual battery cells arranged to a second battery stack having a second voltage rating in operative communication with a second output, the second output having the same voltage rating as the second battery stack;
- and a third plurality of individual battery cells arranged into a third battery stack having a third voltage rating in operative communication with a third output, the third output having the same voltage rating as the third battery stack;
- a battery management system wherein the battery management system is able to recognize or be programmed to recognize battery type of the battery cells within each of the first battery stack, the second battery stack and the third battery stack;
- and
- a charger in operative communication with, and operable to recharge, each of the first, second, and third battery stacks.
3 more elements
A method of discharging a battery pack comprising:
- receiving a connection to an apparatus in one of a first output, a second output, and a third output of a battery pack;
- providing a first battery stack, a second battery stack and a third battery stack;
- adjusting the battery pack in response to at least one identifying indicia on the battery stack corresponding to a battery type;
- and
- discharging power from at least one of:
- the first battery stack in response to receiving the connection in the first output;
- the first battery stack and the second battery stack in response to receiving the connection in the second output;
- and the first battery stack, the second battery stack, and the third battery stack in response to receiving the connection in the third output.
5 more elements
A method of charging a battery pack comprising:
- receiving a connection to an external power source by a plug on a battery pack;
- providing a first battery stack, a second battery stack and a third battery stack;
- adjusting the battery pack in response to at least one identifying indicia on the battery stack corresponding to a battery type;
- and
- delivering power through a charger carried in the battery pack to one or more of the first battery stack, the second battery stack, and the third battery stack, according to the relative power levels thereof such that power is first delivered to the battery stack with the lowest charge level before delivering power to battery stacks with higher charge levels and wherein the first battery stack, second battery stack and third battery stack have the same battery cell types.
