3.13 Climate and environmental concept
The charging station is equipped with an intelligent climate and temperature control. The
following components form the basis for this:
• Multiple built-in temperature sensors and humidity sensors
• Roof fan
• Fan in the automation area
• Fan heater in the door
• Converters with temperature sensors and dedicated fans
• Cooling unit of the CCS charging cable, consisting of fan and coolant pump (optional)
Heating and cooling
The fan heater regulates the climate in the charging station at low temperatures or at high
humidity. The permitted operating range of the installed components is, therefore, not
exceeded.
At high temperatures, the fans cool the components as required. If the cooling capacity is not
sufficient, then the charging power is reduced by derating. The reduced charging power
results in less heat loss in the charging station. This avoids overheating of the components.
If the temperatures in the charging cable require it, then the cooling unit of the CCS charging
cable is switched on. The heating up of the charging cable is determined mainly by the
duration and amount of the charging current. If there are high ambient temperatures at the
same time, then the maximum possible charging current can be reduced.
Noise emissions
If the temperatures inside require it, then the fans are activated. This minimizes noise
emissions from the charging station. If the "Noise level adjustment" option is configured, you
can use the SCB to set the maximum noise emission as a guide for the behavior of the
charging station. The charging power is regulated in such a way that the defined high limit is
not exceeded. In addition, you can set the maximum permissible noise level based on time.
These settings minimize noise pollution at night, for example.
Through a limiting of the maximum noise emission, the available charging power can be
reduced. The available charging power depends mainly on the ambient conditions and the
temperature inside the charging station.
