Steca SVE-822

Parking space supply unit with process-controlled chargers for lead batteries


The parking space supply unit SVE-822 consists of an aluminium column with one (SVE-822-E) or two (SVE-822-D) chargers. Up to two vehicles can be charged simultaneously and independently of each other. The connection of the bus to an optional bus information module (BIM) also allows identification of the respective vehicle as well as heating control and query of the ignition status. This is particularly relevant for bus depots. Via the RS485 interface, these data can be managed centrally and individual parameters can be changed. Due to the processor-controlled charging process, the batteries are charged gently and quickly.
