We're looking to build a DC migrogrid at CCCamp19.

Name

Forty Eight Grid Teanm Forty Eight

-> 42?

List of recommended devices

  • Soldering Irons
  • Lab PSU
  • Battery Chargers
  • Networking Hardware
    • Switches
    • WiFi APs
  • Laptop chargers

Power Out Boxes

48V-> 24/12/5V

  • DC sockets
  • Car sockets
  • USB
  • Switches + Fuses
    • What kind of fuse?
  • Volt/Amp Measurment - "Battery computer" -> Stats via LoRaWAN?

USB Charging Station

I have two 48V->5V DCDC converters (Product page, datasheet), which we could used tu build USB charging stations for powerbanks etc.

  • USB "power sensing" via data pins: [1], [2], [3]

Power In Boxes

12/24V -> 48V

  • Schottky Diode
  • Fuse / Currentlimiting
  • Batterymonitor / Datalogging -> LoRaWAN?
  • Auto-Disable with Under/Overvoltage
