Improvements in the circuit structure of the group. As is well known, the battery pack is widely used in the market for notes, brains, electric devices, electric bicycles, electric motors, electric scooters, and electric vehicle materials. Commercially available rechargeable battery packs are composed of a plurality of battery cores. The battery pack has a pair of electrodes externally connected to the internal series cell cores _ electrical positive and 贞 electrical terminals. Under this _ circuit structure, a plurality of battery angers can only be charged and discharged in series; however, the more the number of cells in series, the more difficult it is to make the battery cells have equal storage and discharge capacity, and the battery pack is more likely to be generated. Aging effect, shortening the service life 0 This paper proposes a battery circuit structure with a plurality of counter electrodes. The battery pack has a plurality of counter electrodes externally, and the plurality of counter electrodes are respectively connected to the electrical positive and negative conductive terminals of the series battery cells inside the battery pack. . Any battery cell of the battery cell can be charged individually or battery voltage; if equipped with a suitable charger, the battery pack can be charged individually or in a single cell. Multiple single battery cells are charged at the same time to shorten the charging time; with appropriate chargers, high-accuracy charging control, each cell has equal storage capacity. 'The aging effect of the battery pack is not easy to produce, and the service life is longer; The battery pack can also perform individual discharge of a single cell or series discharge of a plurality of series cells. [Prior Art] A conventional battery pack of a rechargeable nickel-hydrogen battery, a nickel-cadmium battery, a lithium-cobalt battery, a lithium-powered battery, or a clock-iron battery is connected in series by a plurality of battery cells (or Parallel connection of a few M341313 electric (and then connected in series) circuit structure, the output voltage of the battery pack can be accumulated as a multiple of a single battery ~ the battery pack's storage capacity and discharge can also be accumulated, single - 胄 battery core Times. As far as the actual case is concerned, the battery pack's rated input voltage can be volts, volts 24V volts, volts, 48V volts, volts, 72V volts, volts, surface volts, blue volts, gallbladder, volts, volts, and Volt, series of renewals can be 5Ah, cutting, time, cutting, time, coffee, tree, m, 25Ah, 3_an, time, face, small, hour, 5 ampere Hours, 6_Amp hours, 80Ah amp hours, 1 〇〇 amp hours, 20 amp hours, 4 amps _ and so on. There are only _ counter electrodes on the outside of the battery pack, and the pair of electrodes are respectively connected to the electrical positive conductors and the electrical negative conductive terminals of the internal series battery core group. Under this circuit structure, a plurality of series battery cells can only be charged in series, and any one of the battery cores cannot be individually charged, and the voltage of any one of the battery cells cannot be measured. The output voltage of the charger must be slightly higher than the output voltage of the battery pack before charging; however, based on cost considerations, the voltage sensing component and current sensing component of the charger have only one 1-bit or 12-bit solution. Lu analysis ability, if the output voltage of the charger is higher and the output current is larger, the charging control accuracy of the charger will be lower; however, the low-accuracy charging control is likely to cause partial charging and over-discharging of the battery core, as long as One of the battery core functions is attenuated, and the function of the battery pack is also attenuated, which affects the application of the battery pack (Note: The application of the Republic of China Patent Institute 1255061 by the Industrial Technology Research Institute of the Foundation) has relevant instructions. Therefore, how to find a battery circuit structure that can perform individual charging of a single battery cell to improve the aging effect of the conventional battery pack and increase the service life is a technical problem to be solved. 6 M341313 [New Content] This article provides a battery structure with a plurality of counter electrodes.

In other words, in other words, 'the filling of U and the number of Wei scales. Even if the voltage sensing element and current_ component of the charger have only the resolution capability of 1Q bit or 12 bits, there is still a higher degree of charge correction. Secondly, the charging of the number of electricians can be electrically isolated, and a plurality of single cell cores can be simultaneously charged to shorten the charging time. This is in line with the need for rapid charging of electric vehicles. After the rain is accurately charged, each cell has an equal amount of stored electricity, and the aging effect of the battery pack is not easy to occur, and the service life is longer.
