New Energy Vehicle Industry Background
In recent years, the new energy industry has developed rapidly under the strong support of the government, driving the rapid rise of new energy vehicles in the fields of household and commercial use. As an important measure of the dual carbon goal, the new energy vehicle industry has ushered in unprecedented opportunities and has gradually entered a period of rapid development in the true sense.
The outstanding difference between new energy vehicles and traditional vehicles is the big three electric components and the small three electric components. The big three electric components refer to the motor, battery, and electronic control; the small three electric components refer to the DC/DC converter and OBC.

OBC/D2D Industry Background
OBC/D2D is the core component and the power source of electric vehicles. It converts the alternating current on the grid into direct current that can meet the charging requirements of electric vehicle batteries. And it protects and controls the charging process of the battery according to the characteristics of the battery to avoid damage to the battery due to improper charging.
In order to reduce costs, reduce space occupation, and enhance the core competitiveness of technology, electronic control components such as OBC/D2D are increasingly integrated.

OBC/D2D Test Solutions
To realize the above tests, it is necessary to configure the power source, including a DC power source, an AC power source, as well as a power analyzer, a DC electronic load, and other instruments. Relevant test items put forward high requirements for the dynamic, rapidity, and adaptability of electronic loads.
- CV Under-voltage Protection Test: The under-voltage protection is mainly to find the under-voltage protection point accurately.
- Short-circuit Protection Test: Simulates an overload test requiring the electronic load to reach the maximum current value in a short time (usually within 5ms).
- OBC/D2D Compatibility Test: OBC has the characteristic of high voltage and small current, while D2D features low voltage and high current.
