Claims42
A rechargeable battery assembly, comprising
- a rechargeable battery having a positive terminal and a negative terminal, and
- means for self-discharging the rechargeable battery when a voltage across said terminals is greater or equal to a preset value, said means for self-discharging being electrically connected in parallel with the battery terminals.
A rechargeable battery parallel set assembly, comprising
- a plurality of rechargeable batteries, each having a positive terminal and a negative terminal electrically connected in parallel to form a parallel battery set, and
- means for self-discharging the parallel battery set, said means being electrically connected in parallel with said parallel battery set, to self-discharge said parallel battery set when a voltage across the parallel battery set is greater or equal to a preset value.
A rechargeable battery series set assembly, comprising
- a plurality of rechargeable batteries, each having a positive terminal and a negative terminal electrically connected in series to form a series battery set, and
- means for self-discharging the series battery set, said means being electrically connected in parallel with said series battery set, to self-discharge said series battery set when a voltage across the series battery set is greater or equal to a preset value.
A rechargeable battery parallel-series set assembly, comprising
- a plurality of rechargeable batteries, each having a positive terminal and a negative terminal electrically connected in parallel to form a parallel battery set,
- a plurality of said parallel battery sets electrically connected in series to form a battery parallel-series set, and
- means for self-discharging the battery parallel-series set, said means being electrically connected in parallel with said parallel-series battery set, to self-discharge said parallel-series battery set when a voltage across the parallel-series battery set is greater or equal to a preset value.
A rechargeable battery series-parallel set assembly, comprising
- a plurality of rechargeable batteries, each having a positive terminal and a negative terminal electrically connected in series to form a series battery set,
- a plurality of said series battery sets electrically connected in parallel to form a battery series-parallel set, and
- means for self-discharging the battery series-parallel set, said means being electrically connected in parallel with said battery series-parallel set, to self-discharge said battery series-parallel set when a voltage across the series-parallel battery set is greater or equal to a preset value.
A rechargeable battery pack assembly, comprising
- a plurality of rechargeable batteries electrically connected in series, parallel or a combination of series and parallel, and
- means for self-discharging the rechargeable battery pack when a voltage across said battery pack is greater or equal to a preset value, said means for self-discharging being electrically connected in parallel with the battery pack.
