AC EV wallbox

Car electrification is well underway and numerous countries have ambitious plans to rule out new petrol and diesel in the near future. One of the critical challenges in making electric vehicles more common, is the availability of accessible charging points. Standard AC wallboxes (offering between 3.6 kW (single-phase) and 22 kW (three-phase) of AC charging) are currently the most common and cost-effective residential option. With bidirectional technology (allowing electricity to flow into and out of EVs) rapidly maturing, this will enable cars to become mobile storage platforms and be fully integrated into smart grid infrastructures.

Design considerations

  • A single-phase or three-phase home grid connection has the greatest impact on design and topology choice, although charging speed is ultimately controlled by the vehicle's OBC / BMS capabilities
  • Slower single-phase systems are ideal for overnight charging, although higher power 22 kW AC chargers can be also be useful for semi-public charging in parking spaces or office locations
  • To minimize BOM cost and footprint, voltage regulator with power switch integrated in auxiliary power supply is usually adopted.
  • Inrush protection circuit (NTC, varistors, etc.) should be considered to prevent potential damage when charging starts

Improve accuracy of AOI in PCB production by using modern package technology

To enhance AOI Nexperia has introduced its new lead shape which is featured in packages such as the CFP15B and CFP2-HP. Watch this video and learn how this new lead shape delivers a more uniform solder joint which is easier to detect with AOI.
