TIDA-010239
概述
Electric vehicle supply equipment (EVSE) facilitates power delivery to electric vehicles safely from the grid. An EVSE control system consists of an auxiliary power stage, an off-board AC/DC high-power stage (only in DC charging stations), energy metering unit, AC and DC residual current detector, an isolation monitor unit, relays and contactors with drive, two- way communication over single wire, and service and user interfaces. This reference design, an addition to the TIDA-010939 Electric Vehicle Supply Equipment (EVSE) front-end controller, highlights an ultra-low standby isolated AC/DC auxiliary power stage with super capacitor back-up power supply, an efficient relay and contactor drive and isolated line voltage sensing across the relay and contactor.
特性
- Ultra-low standby UCC28742-based isolated 29-W AC/DC stage to improve energy efficiency
- Supercapacitor backup supplying up to 7.5 W for 3 seconds during energy storage release (AC mains failing)
- Ultra-low standby as well as cost-optimized converters and linear regulators to power up points-of-load
- DRV8220 current controller to drive high-current relays and contactors
- Isolated line voltage sensing using a single TLV7021 comparator for welded relay and contactor detection
