With the continuous development of the EV industry, EMC testing laboratories for EV are also rapidly being built. 

As an important supporting facility, the standard specifications of EV charging system (charging piles) are also being gradually improved.

At present, CN standard AC charging pile (slow charging) uses CP communication signal as shown in the figure, while the DC charging pile (fast charging) uses CANBUS signal for transmission. 

As a professional EMC filter manufacturer, WEMC provides related filters for power, CP, CANBUS of charging piles in corresponding systems of EMC chambers.

After the accumulation of a lot of projects, WEMC has been well experienced of such solutions. WEMC is also experienced in solutions of EU EV charging standards, which differs from CN standards.
