Embodiment
The described nonaqueous electrolytic solution rechargeable battery of embodiment of the present invention is Li-Ion rechargeable battery, and is called for short rechargeable battery.
As shown in Figure 3, the embodiment of the invention provides a kind ofly carries out a plurality of charging structures that are nonaqueous electrolytic solution rechargeable battery in parallel with parallel charger, it mainly is comprised of two secondary cells 21,22 and 1 first charger 30 and one second charger 40, wherein:
Each secondary cell 21,22 has an anodal cartridge 211,221, an and negative pole head 212,222, and each anodal cartridge 211,221 is electrically connected mutually, and each negative pole head 212,222 is electrically connected mutually, makes two secondary cells 21,22 be state in parallel.
The first charger 30, have first positive output terminals 31 that are electrically connected with each anodal cartridge 211,221, and one with each negative pole head 212,222 the first negative output terminals 32 that are electrically connected, make the first charger 30 be state in parallel with this secondary cell 21,22 respectively.
Special feature of the present invention is: set up one and have the second positive output terminal 41 that the one and first positive output terminal 31 is electrically connected, and the second negative output terminal 42 of the one and first negative output terminal 32 electric connections with the second charger 40, the second chargers 40 of the first charger 30 identical charging currents.
The present invention carries out a plurality of charging methods that are the nonaqueous electrolytic solution rechargeable battery of parallel connection with parallel charger, be secondary cell 21 in parallel with 30 pairs two of first charger, 22 charge, the present invention set up especially one with the second charger 40 of the first charger 30 identical charging currents, the second charger 40 and the first charger 30 are parallel with one another, and look the electric current total value of exporting and export with the first charger 30 mean allocation electric current total values, in the present embodiment, the electric current total value that order is exported is 1 unit, at this moment, the first charger 30 and 40 current values of exporting respectively 0.5 unit of the second charger, and be that the electric current total value of 1 unit reaches each secondary cell 21 again, 22 operations of charging.
