In the next three years, which main control board functions for charging piles will become operational standards? For example, V2G, orderly charging, and carbon credit reporting

n the next three years (2025-2027), the "operational standard configuration" will no longer refer to simple scanning and activation but will instead encompass "the ability to connect to virtual power plants, sell electricity, and calculate carbon emissions." Based on policies, pilot progress, and the latest bidding technical specifications, it can be determined that the following six functions will transition from "optional" to "mandatory acceptance criteria." The main control board must reserve hardware interfaces and MCU computing capacity margins during the design phase; otherwise, it will be ineligible for operator orders starting in 2026.

1.Bidirectional charging and discharging (V2G/L) -2027 mandatory "discharge all that should be discharged"

The action plan has been quantified: by the end of 2027, there will be at least 5000 new bidirectional charging and discharging stations in China, with a reverse power output of ≥ 20 million kWh, and the discharge capacity will be included in the settlement of the provincial power grid. The pilot projects in Guangzhou, Beijing, and Wenzhou all require newly approved projects to "synchronously design V2G topology", and the main control board must support:

• Measurement channels ≥ 2 channels (forward/reverse independent refresh time of 0.2 seconds each)

• CAN isolation transceiver ≥ 3 channels (pile vehicle PCS parallel)

• Firmware Reservation GB/T 27930-2026 Bidirectional Message Stack

2.Intelligent and orderly charging (load balancing) - included in the government subsidy whitelist from 2025 onwards

By the end of 2025, of the newly built residential communities in Guangzhou/Shenzhen must be connected to virtual power plants, and the main control board must have the ability to respond in seconds and dispatch within 15 minutes. The bidding documents of the operator have stated:

• Adjustable power step ≤ 1%

• Dispatch instruction response time ≤ 3 seconds

• Offline network disconnection allows local AI to continue executing day ahead curves (edge LSTM model ≤ 2 MB)

3.Real time reporting of carbon credits - Carbon market "MRV" automation

Starting from Q2 2025, multiple carbon emission exchanges will include "green charging for new energy vehicles" in CCER, requiring the pile side to provide a corresponding table of "electricity quantity carbon factor" with a particle size of 1 Hz. The main control board needs to be built-in with:

• Electricity metering SOC (0.5% accuracy, 6000:1 dynamic)

• RTC+temperature compensation ensures traceability of 10-year power curve

• MQTT/REST breakpoint resume, data not lost for 7 days after power failure

4.Optical storage charging microgrid collaboration -2026 comes standard with "one cabin and four modes"

The new generation of megawatt level supercharging stations have integrated photovoltaic MPPT, energy storage BMS, V2G, and DC bus monitoring into the same main control PCB, saving 43% of land and reducing investment by 20%. The main control board must:

• Support parallel connection of Modbus TCP and energy storage PCS

• Bus voltage sampling 1000 V isolation, ± 0.5% accuracy

• Support IEC 61850-9-2LE sampling protocol for easy access to power grid DTU

5.Plug and Play (PnC)+Digital Key - Unified Requirements for 2026 Operator Platforms

BYD, Ideal and Weilai 2025 all series began to push the "vehicle pile non sense authentication", and the main control board needs to integrate the BLE+UWB+NFCC three in one module, and complete cloud authentication in 0.8 seconds. The bidding scoring table sets "plug and play success rate<99%" as a disqualified item.

6.Predictive O&M - Reduce on-site attendance by 60%

The dual MCU architecture of the main control board (main control+monitoring) has become a de facto standard: the monitoring core can cut off the relay within 200 µ s, and the cloud AI issues a "board replacement" work order 48 hours in advance based on the number of relay closures, capacitor ESR, and fan speed, which can reduce the annual attendance from 0.8 times to 0.3 times. Starting from 2026, the quality assurance bidding documents of operators will require a "critical component life prediction report", and boards without edge data collection capabilities will be directly eliminated.

Implementation timeline (can be directly referenced when written into the technical plan)

• 2025 Q4：V2G、 Ordered charging and carbon credit reporting are included as prerequisites for government subsidies

• 2026 Q2: If the success rate of plug and play charging is less than 99%, it will be considered a significant breach of contract and the operating contract may be terminated

• 2027 Q1: Old piles without "bidirectional metering+virtual power plant interface" will be included in the priority removal list for power grid restrictions

one-sentence summary

From 2025, the "main control board" must be "power router+carbon meter+edge computer" at the same time. Without any one, operators will not get tickets in the next three years.

The main control board of the communication charging pile produced by Xincheng Technology is of good quality and price. Welcome to inquire and purchase!
