What essential capabilities must a high-quality AC charging pile motherboard possess?

Xincheng Technology Reveals the Hardware Capabilities List of a High-Quality AC Charging Station Motherboard

(Compliant with the latest 2025 standards, based on actual testing and disassembly, ensure goods are picked strictly according to the list.)

1. Safety Lock: Chip-level Life Protection

A+6 Leakage Protection

• Type A +6mA DC fluxgate chip (RCMU101SN-E), 0.1ms hardware closed-loop, trips at 8mA rain membrane, 50 times more sensitive than the old 300mA.

0.1ms hard emergency stop

• Dual MCU mutual inspection, overcurrent/overvoltage/overtemperature protection with <50ms cutoff, I²t energy reduced by 85%, no arc at no-load break point.

-40°C to 125°C full operating range

• AEC-Q100 MCU, -40°C electrolytic capacitors, 125°C relays, withstanding a full charge and no freezing at -25°C in northern conditions.

2. Metering Lock: Meter-Level Precision

0.5 level measurement SOC

• Juquan HT5015/HT70366000: 1 dynamic, error<± 0.5%, saving 30% cost compared to external electricity meters.

± 1% voltage/current stability control

• 0.1ms current loop+AI edge NPU, stable voltage ± 1%, stable temperature ± 1 ℃, avoid overcharging or undercharging.

3、 Communication lock: plug and charge

Matter over Thread

• NRF5340, 0.3 µ A sleep, 3ms wake-up, HomeKit native access, no gateway.

4G/5G+PLC dual stack

• 4G Cat.1+PLC S-FSK， Rainy night 4G disconnection → PLC seamless switching in 0.2s, availability rate>99%.

Plug and charge 3-second closed-loop system

• BLE+NFC+VIN authentication, completed settlement within 3 seconds after inserting the gun, with a success rate of 99.8%.

4、 Authentication Lock: Global Passport

CCC+CE+UKCA+UL2202 complete set

• 5kV isolation, 6mA DC, -40 ℃, anti quantum encryption, UL2900-2-2 pre-approval.

MTBF≥50,000h

• Relay 100000 times, capacitor 2000h@105 ℃, annual failure rate<0.1%.

5、 Intelligent lock: AI edge+carbon ledger

AI Edge NPU 1 TOPS

• LSTM+Nash equilibrium, completed multi pile power redistribution in 0.2 seconds, and the utilization rate of the entire station increased by 18%.

Blockchain settlement

• ESAM SM4+hash on chain, "on chain hash" per kilowatt hour, anti cloning card, settlement error of 0.05%.

6、 Low temperature lock: Start at -40 ℃

-40 ℃ full device AEC-Q100

• MCU、 Capacitors, relays PCB、 The sealing strip has a specification of -40 ℃ and can be fully charged overnight at -25 ℃ in the north.

one-sentence summary

A high-quality AC charging station motherboard="0.5 level metering+6mA flux gate+1 TOPS NPU+Matter over Thread+global certification+-40 ℃ full device" - not more code, but harder safety, wider temperature, longer lifespan, and more comprehensive certification. This is the whole truth of 2025.

The communication charging pile motherboard produced by Xincheng Technology has strong strength, beautiful quality and excellent price. Welcome to inquire and purchase!
