The company Gouach Batteries is working on the Infinite Battery device, which will help electric bicycle owners save money and benefit the environment. This is reported by Notebookcheck.
At first glance, batteries for electric vehicles and e-bikes appear to be fully customized, specialized systems. They typically consist of individual cells connected through specialized electronics. These individual cells can also be purchased to replace old ones, but replacing them on your own can be challenging.
As part of a crowdfunding campaign, Gouach Batteries is raising funds for the Infinite—a user-serviceable battery for e-bikes priced at $249 per unit.
According to engineers, just a few damaged cells can lead to a complete battery failure in 90% of cases, which can result in high costs and environmental issues.
The innovation aims to circumvent this problem by making individual battery components easily replaceable: accessibility is ensured through screw connections. Individual components only need to be inserted into the corresponding holders, and soldering is not required.
The Infinite incorporates a sensor system that not only provides readings of voltages, currents, and temperatures but also acceleration and humidity. These values can be easily monitored via an app, with the ESP32 chip enabling Wi-Fi and Bluetooth connectivity. The casing is also considered fire-resistant and certified to IP67, meaning it is waterproof.
Compatibility is guaranteed with a wide range of electric motors and bicycles from Shimano, Yamaha, Decathlon, Brose, and Bosch, although batteries fully integrated into the frame cannot be replaced, they can be used as range extenders.
The Infinite Battery is available in 36 or 48 volts, with capacities of 460 or 450 Wh, and a maximum continuous power output of 900 or 1200 W. Both options weigh 3.6 kg.
Previously, American freight train manufacturer Wabtec, in collaboration with Carnegie Mellon University, also introduced the world's first battery-powered electric locomotive, which operates on 18,000 lithium-ion batteries, delivering the same power as a hundred Tesla cars.
