solar electric vehicle charging station

solar electric vehicle charging station S&D Powernics developed a new Hybrid EV Charger and Grid peak demand reduction system which overcomes following limitations of current

EV Chargers :
-By direct Battery to Battery charging, demand from the power Grid is eliminated while EV batteries are being recharged at maximum power rate
-Series-compensated, DC to DC Converter provides fast and yet safe "Battery to Battery Energy Transfer".
-Input Bi-directional Converter works normally as AC to DC Converter and recharges the batteries in the charger system during off-peak hours.

However, it can be programmed to instantly change to a Grid-tie inverter by discharging the Batteries.
• ACto DC mode : InternalBattery Charging
• DC to AC mode : Peak Load Reducer I Grid-tie Inverter
PV Converter
MPPT charging method for optimized balance of charging speed& battery safety.
Series-Compensated DC/DC Converter
The proposed converter topology is easily implemented with the conventionalNS fullbridge DC/DC
converter because only battery connection is needed as shown in figure shown above. With only one
additionalconnection, the conventionalNS fullbridge DC/DC converter with rated power is transformed
into new high power conversion stage by battery.
Battery in EV is Recharged by "Battery-to-Battery Energy Transfer Circuit".
This technology provides extremely fast 8.J battery recharge time
