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.
