Embodiment 1

[0041] In this case, monomer B is matched with 10%, 20%, and 30% of the battery capacity of monomer A respectively. The blue electric test machine is used, and the victory VC189 is added to the PC terminal to collect the current distribution. The recording point is 1s, and the recording time is 300s. The parallel matching of batteries occupies the percentage of current distribution respectively, see 10% matching Figure 5 , the single group B battery bears 100%~38% of the current, and the single group A battery bears 0%~62%. See you with 20% Figure 6 , the single group B battery bears 100%~57% of the current, and the single group A battery bears 0%~43%. See you with 30% Figure 7 , the single group B battery bears 100%~72% of the current, and the single group A battery bears 0%~28%. This shows that the discharge response speed of the single group B battery is fast and the current capacity is strong. It can play a role in short-term power supply, buffering load fluctuation...

Embodiment 2

[0043] Cell B is the 10% life test of cell A capacity --- HRPSoC, the battery enters the test at 50% SoC, 2C current cycle charge and discharge, until the cut-off voltage cycle is completed, fully charged and then enters the test at 50% SoC, such as Figure 8 . The pure battery group A of the single cell cannot be tested after a total of 8177 times in the 10th cycle, and the super start-stop starter battery of the battery group A in parallel with the battery group B of the single cell can still run, and the test is not continued until the 35th cycle after a total of 14979 times. Figure 9 . The principle is that when discharging for a short time, group B of the monomers, such as case 1, bears a large current. When it is left on hold for 10s, the balanced voltage of group A of the monomers will supply power to group B of the monomers. The two are also voltage balanced. From this experiment, it can be seen that after increasing the capacity by 10%, the life of the monomer A and...

Abstract

The invention discloses a super start-stop start-up battery. A battery cover is arranged at the upper end of the battery casing, and a plurality of single cavity A and single cavity B are respectively arranged at both ends of the battery casing through separators. The monomer cavity B is arranged vertically or parallelly. There are several monomers A and B. The monomer A is arranged in the monomer cavity A in series, and the monomer B is arranged in series. In the cavity B of the monomer, the monomer A and the monomer B are connected in parallel, and the upper ends of the monomer A and the monomer B are provided with a busbar, and the busbar is fixed by a number of pressure columns, and the two ends of the busbar are respectively connected with the terminals. The structure is reasonable, making full use of the internal space of the battery shell, which can adapt to the ratio of the number of monomers A and B. The battery of the monomer B group has a fast discharge response speed and a strong current capacity, which can provide short-term power supply and buffer load fluctuations. , Balance power output, improve power quality, etc., thus ensuring the life of the start-stop battery.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a super start-stop starter battery. Background technique [0002] The rise in global temperature has intensified the hazards. Governments and automobile companies have generally recognized that energy conservation and emission reduction are the main direction of automobile technology development. At present, the market mainly promotes pure electric and hybrid new energy sources. The cost of electric vehicle systems using lithium batteries and other related batteries is relatively high. Higher, the charging distance is shorter. With the development of modern science and technology, lead-acid start-stop batteries have been widely used, but compared with the existing start-stop batteries in the market, the service life is shorter. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art . Contents of the invention [0003] The pur...
