What are the advantages of large-capacity single lithium batteries

1. Small internal resistance and good safety. When a large-capacity single lithium battery replaces an energy module that requires many small-capacity batteries in parallel, it has good consistency, and the data collected by the module through the BMS is credible. A battery that fails due to a short circuit of a single circuit of many batteries in parallel will quickly exhaust the power in other batteries and cause a fire. Therefore, only by using a single large-capacity battery can we guard against the above-mentioned drawbacks. At the same time, since there will be no internal self-reflow phenomenon of parallel batteries, under the same conditions, the larger the battery cell capacity, the lower the internal resistance, and the lower the operating temperature. Compared with the parallel battery module of the same capacity, the load capacity will be increased and the operating life will be extended. 2 , Fewer connection points, lower failure rate The fewer the power system connection points of the large-capacity single lithium battery, the lower the probability of accident. At present, the industry is equipped with pure electric buses. If the power modules of 480V500Ah are connected in series with 10Ah, there are as many as 7,500 batteries. There are as many as 15,000 positive and negative connection points. However, only 150 single 500Ah batteries need to be connected in series, which greatly reduces the probability of accidents. 3. The single-chip large capacitor of large-capacity single lithium battery, the power management system is controllable. Many battery packs caused by parallel connection can only reflect the data of one of the highest electromotive force batteries in the power management system. This blind spot of undetectable monitoring is caused by Single large-capacity batteries are replaced and eliminated. 4. Solid polymer design, low temperature resistance and safer. The single large-capacity power lithium-ion battery manufactured by Shenzhou Giant Electric uses solid polymer structure to improve the low-temperature working ability and overcome the liquid battery seepage, flammability and verticality. The limitation of placement, because the battery can be placed horizontally and at will, Zhang has expanded the design space of pure electric vehicles, and also reduced battery damage caused by vehicle bumps. 5. Convenient for large-scale processing and standard operations. Automated assembly lines can be used to uniformly carry out operations such as serial operation and module boxing to meet the requirements of automotive-grade industrial accessories, achieve large-scale processing of power modules at the lowest cost, and greatly reduce application costs.
