Thanks to the development of new processes, the Karlsruhe Institute of Technology (KIT) in Germany and Coboc soon to offer an e-bike battery pack that can be recharged in less than an hour.
While it takes two to four hours or longer today to charge an electric bike, the Karlsruhe Institute of Technology (KIT) and the electric mobility company Coboc want to speed things up by developing a new generation of rechargeable batteries.
A new process relies on specific lithium-ion cells. It is capable of tolerating a charging current much higher than the cells usually used on e-bikes, which is able to go up to 10 amperes. Such strong current allows
Besides that, both partners are working on a new battery management system, the famous BMS (Battery Management System), which must better track the state of charge (SOC) and health (SOH) of the battery that can influence each other. Once saved and transmitted from BMS, the data will then be made available to manufacturers and users. This will facilitate further experiments and monitoring.
In practice, the KIT is in charge of cell selection and rapid charge process development while Coboc is focused on needs analysis and development of the tracking device.
Partly financed by the Federal Ministry of Economic Affairs and Energy (BMWi), the program will end in September 2021.
