Background: The Rapid Evolution of EV Charging Technology As electric vehicle (EV) adoption accelerates, the demand for faster and more efficient charging solutions is growing exponentially. The industry is witnessing a clear power trend in charging technologies:

What Is "PV + Storage + Charging" (PSC)? As carbon neutrality and peak carbon emission goals are gradually being implemented, the energy storage market is witnessing explosive trillion-level growth. Amid the imbalance between the rapid development of electric vehicles and charging infrastructure, the integration of solar power generation, battery energy storage and EV charging—referred to as “PV + Storage + Charging” (PSC)—is emerging as an innovative solution for building greener, safer, and more efficient EV charging stations.

In new energy vehicles, the motor and power battery are undoubtedly key components, but there is another key device that is easily overlooked - the inverter. Whether it's in models equipped with permanent magnet synchronous motors or three-phase asynchronous motors, the inverter exists as a key component. The reason why the inverter is so important is that the power battery outputs DC power, which must be converted when supplying power to the AC motor.

With the rapid development of electric vehicles, testing of high-voltage components has become increasingly critical. High-voltage components are the core components of electric vehicle power systems, mainly including battery packs, motor controllers, high-voltage cables, etc. These components are directly involved in the storage, conversion and transmission of electrical energy, and are directly related to the performance, safety and overall reliability of the vehicle. Therefore, the testing of high-voltage components of electric vehicles is particularly important. ISO 21498-2 came into being in this context.

With the rapid development of the new energy vehicle industry, the testing requirements for equipment carrying high-current circuits such as high-current cables, fuses, and contactors are becoming more and more stringent.

As countries around the world vigorously develop electric vehicles, auto makers and various standardization organizations have begun to establish technical development standards and define various EV tests.
