Six basic tests for ev obc and dc/dc

As a provider of modular solutions for new energy vehicles, LANDWORLD is committed to providing customers with safe and reliable products. The company has developed test items, methods, and inspection standards for the DC/DC converters and on-board chargers produced to ensure that the electrical performance, EMC, white box, reliability, and safety regulations of the DCDC converters and on-board chargers meet customer needs and meet current and expected domestic and foreign regulatory requirements.

Visual inspection

Visual inspection is a technique for detecting defects using the naked eye to ensure equipment is working properly or that manufactured products are being made to specification. Including general regulations, appearance dimensions, weight, nameplate, label wiping test, etc

Electrical characteristics

Including DC/DC electrical performance, OBC charging electrical performance, OBC inverter electrical performance, IP protection level, and noise inspection

Reliability testing

The power of EVSE and OBC have increased in general to reduce the charging time, and OBC has evolved from single phase 3.3kW or 6.6kW to three phase 11kW or 12kW. For different types of electric vehicles, many OBC suppliers, on the structural prospect, have introduced integrated products such as OBC and DC/DC converters or OBC, DC/DC converters and PDU. At R&D and production stage, these OBCs all require high performance and high efficiency test & measurement products to ensure their capability and reliability. reliability testing including mechanical load, climatic load, chemical load, frequency of use, durability test

Security testing

Including electrical safety and EMC testing

White-box testing

Including temperature rise, voltage stress, current stress, Electrolytic capacitor life, Loop gain test

Vehicle compatibility

Including two categories: system compatibility testing and CAN diagnostic testing
