Power Supplies for electric vehicle charging
Electric vehicles, and e-mobility, in general, are the future of transportation in a world that needs to reduce its carbon footprint. To make the use of battery powered vehicles cost-effective, EV chargers must be as efficient and economical to build as possible. However, fixed installation wall boxes and charging stations must also comply with overvoltage category three (OVC III) requirements with extended safety specifications to accommodate the potential for significant mains voltage dips, surges and transients, which the on-board power supplies must also withstand. Additionally, temperature variations can be extreme and the environment may be wet, damp, and dirty. The internal auxiliary AC/DC modules must operate reliably under these harsh conditions. Besides the auxiliary AC/DC power supplies, there is also a need for isolated and non-isolated DC/DC converters that provide internal voltage conversion.
RECOM provides a range of low-power AC/DC modules, DC/DC converters and switching regulators that match EV charging application requirements for auxiliary AC/DC supplies and DC/DCs for the internal Distribution Power Architecture (DPA). RECOM’s sister company, RECOM Power Systems, can supply high-reliability custom battery chargers, conditioners and bidirectional inverters based on proven platform designs from single or three-phase AC supplies with power ratings of up to 30kW or even higher with paralleled units.
