With its leading edges at large-capacity Li polymer cells, YOKU ENERGY has been actively working in R&D、testing and market development of multi-cells pack in the past two years. At present, capacity of single cell in multi-cells pack reaches 35Ah, and battery pack with 17 cells in series is available.
As single cell’s capacity of YOKU’s Li polymer battery is larger enough, it is unnecessary to put them in parallel to attain requested capacity while making multi-cells pack. For this reason, number of single cell is reduced significantly, at the same time, reliability and cycle life of battery pack is improved accordingly, this also reduces opportunity of problem occurring, decreases the cost and increases whole-pack’s efficiency. The PMS applied in the battery pack has protection function for each single cell and charging balance function, which ensures each single cell not to be overcharged、over-discharged、overheated, this has well solved the problem of safety and cycle life of the battery packs. Also, it enable multi-cells battery pack to be smart 、high efficiency 、reliable 、durable.
So far, such batteries have been mass produced and put into the market. They are mainly applied in the field of laptop computer batteries, e-bike batteries, power tools, telecommunication equipments, back up power source, etc.
Since this kind of batteries have higher requirement on designing, packing, testing compared with other battery packs , our company provides one-stop service for customers, we produce customized battery packs based on customer’s request.
