With the implementation of the national carbon neutrality and carbon peak goals, the proportion of new energy sources such as wind and solar energy will become larger and larger, and the power generation of new energy sources such as wind and solar energy will fluctuate greatly due to climate and weather. In addition, due to the influence of various factors on the power grid, local short circuits will occur, or the start and stop of large loads will cause a sudden change in the grid voltage (sudden drop or sudden rise). It is difficult to ensure the transient balance of power generation and consumption.

Sunwin vehicle mounted charger is fixedly installed on electric vehicles, and is a small device specially designed for charging electric vehicles. It adopts high-frequency switching power supply technology and is designed by absorbing advanced control technology at home and abroad.

Electric vehicle charging station can quickly charge electric vehicles (charging for 10-15 minutes, more than 80% of the rated power), and monitor the status of the charging host and power battery during the charging process, including distribution room, host room, monitoring room, terminal and supporting facilities. Its construction site requirements are high, large area, complete supporting facilities, and can meet the charging needs of all electric vehicles at the same time. It is suitable for large-scale construction projects such as municipal planning and highway service areas.

The intelligent test load for electric vehicle charging station adjusts the input current and voltage of electric vehicle charging equipment, controls the output load according to the standard, automatically collects multiple signals, and conducts a comprehensive test on its technical indicators in combination with a computer. It mainly completes the authoritative identification, factory inspection, project acceptance, electrical testing, daily maintenance, etc. of electric vehicle charging equipment.

The dual-channel AC charging pile is independently developed and produced by Qingdao Sunwin Technologies Co., Ltd. It is an independent charging platform that provides rated AC power for electric vehicle onboard chargers. The device is equipped with two interfaces at the same time, which can realize the simultaneous charging of two electric vehicles. It is small in size and flexible in style. It is widely used in roadside streets, communities, units, commercial buildings, parking lots, office buildings, commercial streets, large shopping centers, etc.

The high-voltage AC/DC universal load bank is mainly used for load capacity testing, aging and discharge detection of AC equipment and DC equipment. It can be used for both AC and DC, and can be connected to AC or DC loads respectively, which can detect the backup battery of UPS and the load capacity of UPS AC output. The product is manufactured using the company's patented technology with independent intellectual property rights. The power element adopts a new power consumption component with high power density, stable resistance characteristics, flat resistance-temperature characteristics, and easy control.
