SAE J1772-compliant electric vehicle service equipment reference design for level 1 and 2 EV charger Electric vehicle service equipment (EVSE) facilitatespower delivery to electric vehicles safely from the grid.An EVSE control system consists of an auxiliary powerstage, an off-board AC/DC high power stage (only inDC charging stations), energy metering unit, AC andDC residual current detector, an isolation monitor unit,relays and contactors with drive, two-waycommunication over single wire, and service and userinterfaces. This reference design highlights an ultralowstandby isolated AC/DC auxiliary power stagefollowed by converters and linear regulators, acomparator-based control pilot interface to meet theSAE J1772 standard, an efficient relay and contactordrive, and isolated line voltage sensing across therelay and contactor.
参考设计TIDA-010071主要特性:
? Ultra-low standby UCC28740-based isolatedAC/DC stage to achieve ENERGY STAR?certification for EV charging stations
? Tight output voltage regulation (< ±5%) of LDOsand the high slew rate of the TLV1805 deviceensures SAE J1772 certification for the control pilotinterface
? Ultra-low standby as well as cost-optimizedconverters and linear regulators to power up points-of-load
? DRV110 current controller to drive high-currentrelays and contactors for thermal protection andreducing power dissipation
? Isolated line voltage sensing using the ISO1212digital-input receiver for welded relay and contactordetection
