Description

Power-One offers a wide range of battery charger systems

for power requirements of 50 Watt up to 8000 Watt.

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.

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
