about

building on the minimal_bike_charge_controller, and as the next step leading to the open_charge_controller, we have the modular bike charge controller.

design specification

• protection against
  • polarity reversal - not sure how?
  • low battery - switch out battery
  • over current - switch in dump load
  • over voltage - crowbar circuit blows the fuse
  • over heating

• visual feedback
  • modular, choose what you want
  • power in vs power out
  • voltage on battery

• data logging
  • fault conditions
  • kw/h generated, time in use

• modular design
  • choose what visual feedback you want
  • choose number of bikes to use
  • choose battery/super cap and number - dependent on load

• open source
  • diy
  • aim to keep total cost < £50
  • pre programmed microprocessor and pcb available
