In recent years, the charging pile industry has responded positively to policy and market demand, significantly improving system reliability, extending service life and reducing maintenance costs. This not only provides new energy vehicle users with more stable and safe charging services, but also promotes the healthy development of the whole industry and enhances user satisfaction. In terms of improving system reliability, equipment design and material selection is especially critical, especially power supply as the core device, its performance, reliability and delivery time have a decisive impact on the overall system performance.
With the popularization of new energy vehicles and the increase in consumer acceptance of environmentally friendly travel, the demand for charging is growing rapidly. According to statistics, as of October 2023, the number of public charging piles reported by member companies within the China Charging Alliance has reached 2.525 million units, and the growth rate is still accelerating The Chinese government has issued the “Guiding Opinions on Further Constructing a High-Quality Electricity Infrastructure System” and the “Transportation Large-Scale Equipment Renewal Action Program” and other documents, which have clearly put forward the goal of strengthening the construction of charging infrastructure.
To promote the healthy development of new energy vehicle industry, for manufacturers to improve the reliability of charging pile system, the design selection of equipment is really a core key. Especially as the core device of the power supply, its reliability, product performance and delivery time and other aspects of the overall performance of the charging pile system has a critical impact.
DC pile power supply application common demand
01 Input Voltage Requirements
Charging pile usually take power from the outdoor power grid, outdoor power grid in the harmonic interference is large, resulting in the power supply actual input voltage becomes high, up to 290VAC +, or even higher; suburban power grid or some highway remote mountainous area voltage fluctuation range is large.
02Three-proof or fanless half-tank rubber process requirements
Charging pile belongs to the outdoor application conditions, the temperature difference is large throughout the year, and the outdoor environment is more humid, dusty, high temperature/high humidity/dusty environment.
03National standard demand 12V/10A
Considering the auxiliary power supply of BMS in case of high-current charging, the power supply will be standardized as 12V/10A in the latest national standard, and the BMS power supply systems of passenger cars and buses will also be unified.
04Surge and pulse group demand
Charging pile application environment is complex, subject to lightning surge and other electromagnetic interference is also relatively strong.
Program Application
In order to meet the common demand of the market and improve system reliability, the power supply of fanless semi-potted process becomes the ideal choice. In the charging pile industry, this common demand for power supplies is particularly prominent. Choosing a fanless, half-potted switching power supply can minimize noise interference and avoid dust accumulation. For example, Mibo's MLC350 series utilizes this process. With an input voltage range of 90 - 264VAC and a high isolation voltage of 3750VAC, the MLC350 series is a perfect match for the needs of the charging pile industry.
