Ikonix Solution to Optimize EV Charging Station Production Line Tests

The Electrical Vehicle (EV) markets have boomed along with the global sustainable development policy in recent years. Yet, it is facing a big challenge – insufficient EV charging stations. Despite there being more public charging stations than ever, compared to the growing popularity of EVs, more is needed to meet the demands. Thus, governments work on building the EV charging infrastructure to accelerate the EV charging network completion. China’s government has set the goal to deploy enough charging infrastructure to support more than 20 million EVs by 2040.1 The US government also announced freeing up $900 million to build electric vehicle charging stations.2 The ultimate goal is for charging an EV to be as convenient as gasoline. In addition to universalizing the EV charging infrastructure, the EV charging stations’ safety and quality are equally important. Therefore, manufacturers must ensure that their charging station products comply with relevant standards. Standards are critical as it replicates some of the worst-case scenarios that could happen in our known and unknown environment. In this issue, we will introduce applicable international electrical safety standard testing requirements and the Ikonix solutions to optimize the charging station’s production line electrical safety tests.EV Charging Equipment Relevant Standards

Completed EV charging equipment includes the charging station and accessories, such as the socket outlet, plug, cable, connector, and vehicle inlet, and must comply with different safety standards according to the local market. The accessories’ standards are G/T 20234.2 for China, IEC 62196, and UL 2551 for the US and Europe markets.  The charging station must comply with GB/T 18487 in China and IEC 61851, UL 2202, and UL 2594 for the US and Europe markets. All of these standards share some things in common. In the charging station’s production line test, manufacturers should perform Hipot, Ground Continuity, and Insulation Resistance tests on their products. The Hipot testing voltage is up to 4000Vac, and the charging station has to withstand this high voltage for 1 to 2 seconds without breakdown. The insulation resistance is to apply 500Vdc, and the measured resistance should be greater than 1M ohms. Some manufacturers would conduct stricter Hipot tests on multiple points to exceed standard product safety and quality. The testing points include points between the primary circuit and chassis, the primary circuit and secondary circuit, and the secondary circuit and chassis.

Ikonix’s Testing Solution Optimized Our Partners’ Production Line Tests

Conducting the completed electrical safety test with great testing efficiency is always challenging. Therefore, many of our EV charging manufacturing customers have chosen the HypotULTRA® 7850 (SE 7430) and bundled it with SC 6540 (7006) as their production line testing solution. HypotULTRA® series is a compact 4-in-1 safety analyzer that provides up to 5kVac and 6kVdc testing voltage. With SC 6540, operators do not need to switch the testing leads for every testing point. Just connect the main testing leads and click one button to start the test. Greatly optimize the testing efficiency and avoid connection errors. (Ikonix is in the progress of brand consolidation, the eec safety tester will be consolidated to the Associated Research brand, for more information, please read our press release or speak with our sales representative for further details.)

Some of our customers whose production line has limited space would choose Hypot® 3870 (EST-330). This series allows our customers to achieve basic best practices for safety and efficiency without needing an elaborate automated test system. Also, HypotULTRA® and Hypot® have a direct barcode connection that allows the operator to quickly associate products with pre-programmed test files

Ikonix has more than 85 years of industrial experience and has successfully helped many EV manufacturing partners to solve their electrical safety testing challenges. Therefore, if you have any questions about electrical safety testing in the EV industry, please contact us today.
