• Press the equipment stop button (if available).
•
Disconnect the main power supply.
NOTE
The AC Satellite is not connected to a charging power unit. It is connected
directly to the main power supply.
• After extinguishing the fire, always contact Kempower before you start
any maintenance work. Kempower will perform a critical failure analysis
before maintenance work can be done.
2.5. Insulation monitoring circuit
The Satellite includes an insulation monitoring circuit, which fulfills the
requirements of IEC 61851-23:2014.
The internal measurement circuit measures leakage from DC+ and DC-.
When no leakage is detected, operation continues normally. If leakage
current is detected, the output is controlled to shut down and an alarm is
displayed on the charging unit. The current detection limit is 6 mA.
3. KEMPOWER CHARGING EQUIPMENT FOR ELECTRIC VEHICLES
As the design of Kempower electric vehicle charging equipment is modular,
the charging site can be expanded when necessary. The charging
equipment is connected to the Internet and the Kempower ChargEye
system via a cellular or Wi-Fi network.
• Kempower Power Unit is a charging power unit that receives power
from the electric power distribution network and distributes it to 1–8 DC
charging points. The Power Unit can be a single, double, or triple cabinet
unit. Each cabinet can be equipped with 1–4 power modules (C500/500
V and C800/800 V). Charging power management can be dynamic or
static, see 3.1: Charging power management.
• Kempower Station Charger consists of a charging power unit, 1–2 DC
vehicle connectors per cabinet, and a user interface. The Station
Charger can be a single or double cabinet unit.
• Kempower Satellite is the charging point connected to the charging
power unit.
• Kempower Liquid Cooled Satellite is a high-power charging point
connected to the charging power unit.
