METHOD FOR LOADING A TRACTION BATTERY OF AT LEAST PARTIALLY ELECTRICALLY DRIVEN VEHICLES AND LOADING STATION
DRIVE
August 2, 2017
The invention relates to a method and a charging station for charging a cyclically rechargeable traction battery (5) of at least partially electrically powered vehicles (4), in particular electric and/or hybrid automobiles. According to the invention, a charging station (10) comprises a battery storage system (8) and a charging device (7). The charging device (7) comprises an energy transfer device (11) by means of which electrical energy is transferred to a traction battery (5) to be charged. The battery storage system comprises a plurality of cyclically rechargeable batteries (B1 to Bx) which are combined into several battery groups (BG11 to BGn4), wherein starter batteries, in particular motor vehicle starter batteries and/or lead-acid accumulator starter batteries, are used as batteries (B1 to Bx). The battery groups (BG11 to BGn4) feed directly in temporal succession during respectively short battery group discharge time periods (t1 to t30) a traction battery (5) connected in energy-transferring manner with the charging device (7) with a high battery group discharge current, wherein directly successive short battery group discharge time periods (t1 to t30) result in the high battery group discharge current and thus a high charging current (1) for the traction battery (5) to be charged over a longer charging period (T1).
