$250-750 USD

Paid on delivery
We are having 16 spinning bikes generating power at 12V DC constant, 250 Watt output. We want to charge with these devices battery packs for electric scooters. Each battery pack has a rated voltage of 48V and a capacity of 16.8Ah (806.4 Wh). The system needs to be able to charge different battieries in parallel. We are looking for someone to develop the system architecture and the schematics to make this function. Safety and charging speed are the priorities. Outputs of this work: - System architecture document listing all the components needed to build the system - Technical specifications of all needed components. Preferably using components available off the shelf - Electrical schematic how the system shall be wired together - Operational manual how to operate the system - PCB layout + casing design if needed - Software development if needed Detailed requirement spec will be provided after collaboration agreement reached and NDA signed.
