History

AUCOPO started developing and manufacturing e-bike batteries in 2006. After 13 years of R&D, AUCOPO has developed a comprehensive range of e-bike batteries, and has the capability of providing global service coverage.

By far, we have developed 7 models with our own patent under the brand YOKU. The power capacity covers a wide range from 316W to 672W, supporting a myriad of types of our clients' e-bikes all over the world.



Core Competences

Technology
AUCOPO has been producing li-ion battery cells since 2004. More than 14 years’ experience in the industry gives AUCOPO a strong technical understanding of li-ion battery cells & packs of performance, safety and reliability. Our edge is not only the level of quality control, but also our trouble shooting capability. The AUCOPO engineering team with more than 14 years industry experience are ready to support our customers with a wealth of knowledge and know how.

The Battery Cells and BMS
AUCOPO also uses Li ion cylindrical cells from Samsung and Panasonic for e-bike battery packs. The cells used for each battery pack are tightly matched, avoiding cell imbalance and guaranteeing the capacity of battery packs after long term usage.
AUCOPO has developed two kinds of BMS. The standard BMS offers full safety protection features of charge and discharge and cell balance. While the smart BMS adds the data log function, which enables the dealer to see the full end user history and provide after-sales service within the warranty terms.

The Battery Housing
AUCOPO E-bike battery Housings are designed by European designers. The creative battery design makes your e-bike more elegant.

AUCOPO battery housings are all water-proof and have optimized inner mechanical construction. All cells are connected by battery holder and pure nickel plate, which makes the battery packs more stable and resistant violent vibration. These important features ensure the reliability of AUCOPO battery packs.
