Chapter 6 Charge Panel (CP)
USB Charging Panel
Charging Panel Overview
Each Charge Panel is capable of charging 8 NRU at a time.
The charging ports are clear hard plastic cups with 2 springs that line up with the NRU contacts
for supplying voltage to the NRU internal battery charger.
There are no charging electronics inside the charging panels, they are simply distribution points.
The charge circuitry is contained within the NRU.
The Panels are supplied by a 12vdc power supply(s).
Depending on scalability, several panels can be supplied by the same power supply depending
on the output capability of the power supply in use.
At peak charge, a single NRU will draw ~1.2 amps. With 8 NRUs charging a single panel will have
a current draw of ~9.6 amps.
