Temperature Sensors
Description
Power-One offers a wide range of battery charger systems
for power requirements of 50 Watt up to 8000 Watt.
For this purpose Power-One supplies temperature sensors
and adapted power supplies. The batteries (lead acid bat-
teries) are charged according to the battery temperature
and the ambient temerature. If the battery is fully charged it
is maintained at the float charge voltage which represents
the optimum point for maximum available energy in case of
need and optimum life expectancy of the battery. The type
of sensor needed is defined mainly by three parameters:
The nominal battery voltage (e.g. 24 V or 48 V), the tempe-
rature coefficient of the battery (e.g. –3.0 mV/K/cell) and the
nominal floating charge voltage per cell of the battery
at 20°C (e.g. 2.27 V/cell). The latter two are defined in the
specifications of the battery given by the respective battery
manufacturer.
