Is it difficult to use the same set of AC charging station control board, which has passed CE/EN 61851 and UL 2594/UL 2231, for hardware or CP/CC safety strategy?

Hardware is more expensive, CP/CC strategy is more brain burning. Single market, hardware is the main threshold; To achieve dual functionality, the underlying conflicts in CP/CC security policies are the real bottleneck.

In terms of hardware, the UL threshold is higher.

• Leakage protection must use UL approved GFCI scheme, which is more expensive than European standard B-type RCD;

• The electrical clearance and temperature rating are stricter, and sufficient space should be reserved in advance for PCB layout;

• The mechanical structure of American standard gun heads is also different.

• These can be solved by increasing BOM and changing layout.

In terms of CP/CC strategy, physical signals are interconnected, but the security logic is different.

• The European standard adopts a graded response, and in case of abnormalities, the rating can be reduced and an alarm can be triggered first;

• American standard deviation should be immediately cut off, and grounding faults should be quickly disconnected at the hardware level.

• The same sampling circuit, one logic for Europe and another for the United States, the firmware must be able to switch automatically, otherwise it will either trip incorrectly or fail UL testing.

The authentication path is also different.

• UL emphasizes that design is compliance, and safety boundaries must be fixed during the layout phase, making it difficult to conduct retesting afterwards;

• CE has more room for improvement.

Summary:

• Hardware issues can be resolved by spending money, while strategic issues determine whether a single board can be used interchangeably.

•  Only focusing on a single market, hardware is the main challenge; The compatibility design of CP/CC security strategy is the most difficult to eat both Europe and North America at the same time.
