Dry Valley New Energy DC motherboard series: Unlock the "core password" of mandatory certification and empower the quality of charging piles to improve!

2025-2-19

Policy countdown! 3C certification has become the "line of life and death" in the charging pile industryOn March 1, 2025, 3C compulsory certification for electric vehicle charging piles will be fully accepted. Products that have not been certified after August 1, 2026 will face the risk of being banned from sale. The new regulations impose strict requirements on the electrical safety, electromagnetic compatibility, and environmental adaptability of charging piles. Companies urgently need to start with core components to ensure that the entire product design and production process meets national standards. Gangu New Energy is deeply involved in the core control technology of charging piles.DC motherboard series (QGKZD-3N,QGKZD-3M、QGKZD-2W、QGKZD-2）, with "full scene adaptation, high-precision control, and strong safety protection" as its core advantagesBecome the certified “golden partner” of charging pile companies!

Why choose Dry Valley DC motherboard? ——Five core values directly address the pain points of certification

1. All series are compatible with national standards, and certification covers no blind spots.

Dry Valley DC motherboard series fully supports national standard protocols such as GB/T 18487.1-2023 and GB/T 34657-2017, and can flexibly adapt to the diverse needs of AC and DC charging piles. The motherboard has a built-in protocol consistency check module that accurately matches BMS communication to ensure that the charging pile 100% meets certification requirements in terms of electrical parameters, communication interaction and other core indicators.

2.Triple security protection to build a solid certification “firewall”

Electrical safety:Adopting a multi-layer redundant design, it supports multiple protection mechanisms such as overvoltage, overcurrent, and short circuit to eliminate risks such as leakage and insulation failure.
Trouble diagnosis and self-test:The motherboard integrates an intelligent diagnostic system that can detect more than 20 fault scenarios such as CP/CC signal anomalies and charging gun overheating, helping companies verify equipment protection mechanisms in advance and ensure that the safety protection items in 3C certification are passed in one go.
Environmental adaptability:Designed to work in a wide temperature range (-40℃~85℃), it has passed rigorous tests such as salt spray, heat and humidity, and vibration to meet certification requirements for stability in extreme environments.

3. Efficient intelligent control, a powerful tool for reducing costs and increasing efficiency

QGKZD series motherboards are equipped with high-performance MCU chips that support intelligent algorithms such as dynamic power allocation and load balancing. They can accurately regulate charging current and voltage, improving energy efficiency by more than 5%. The motherboard has a built-in automated test interface and is compatible with the Dry Valley test system, which greatly shortens the R&D and debugging cycle and reduces certification costs.

4. Modular design, flexible adaptation to multiple scenarios

QGKZD-3N: Designed specifically for low-power DC fast charging piles. It is suitable for power scenarios below 60kW. It is mostly used for portable DC charging piles. It can also be used for wall-mounted and column-type DC single-charging charging piles below 60kW (network version). A single gun can control up to 8 modules, and the charging power can be flexibly increased or decreased later.

QGKZD-3M：It is mostly used for DC portable charging piles, but can also be used for wall-mounted and column-type DC single-charging charging piles with a power of less than 60kw (integrated version). The built-in insulation detection module is used to measure insulation resistance. A single gun can control up to 8 modules, and the charging power can be flexibly increased or decreased later.

QGKZD-2W：Specially designed for high-power DC fast charging piles, it supports dual-gun parallel output, integrates insulation and networking functions, is suitable for high-power scenarios above 120kW, and meets the needs of efficient operation of supercharging stations.

QGKZD-2: Specifically designed for high-power DC fast charging piles, it supports dual-gun parallel output, integrates insulation functions, is suitable for high-power scenarios above 120kW, and meets the efficient operation requirements of supercharging stations.
