The goal was to create minimalistic solution which would allow faster charging of Peugeot iOn since these cars are equipped with 10A cables from the factory. We have a small board which is possible to be built inside the J1772 connector including power relay (20A) and AC/DC (12V) power converter.
This is an improved version of Simple EVSE 1.0 - it contains onboard relay and also -12V AC/DC converter. This was needed for some vehicles in order to charge (okay, so far only Tesla).
Pretty fast electric bike with amazing acceleration.
Battery management system based on cell modules connected by optocouplers (like BMS123, miniBMS and others).
This is our long-term project which has started in July 2012. Complete propulsion unit was replaced including gearbox. Winston and CALB LiFePO4 cells were installed. Next plans are to test our new BMS system in this vehicle.
48V high speed and long range bicycle. Our first electric bike made.
