The on-board charger OBC is an important device for converting AC to DC when electric vehicles are charged with AC. Due to the difference in power systems, the "three electrics" of electric vehicles replace the fuel tank, engine and gearbox of traditional fuel vehicles. It mainly includes the "power battery, motor controller and motor" of the big three power companies and the "on-board charger OBC, DC/DC converter and high-voltage power distribution box PDU" of the small three power companies.
On-board charger(OBC)can realize the slow charging function of electric vehicles. It is fixedly installed inside the electric vehicle and connected to the AC charging pile during charging to convert AC power into DC power and slowly charge the power battery effect.
Electric vehicle charging can be divided into two types: AC charging and DC charging. AC charging "slow charging" means that the AC charging pile supplies the single-phase AC 220V or three-phase AC 380V in the grid to the on-board charger installed inside the vehicle. AC is converted to DC to charge the power battery, while DC charging "fast charging" uses an external "DC charging pile" to directly charge the power battery without using an on-board charger.
Compared with the high construction cost of DC charging piles, large footprint and the need to be equipped with large transformers to meet power distribution needs, AC charging piles have the advantages of low construction costs, small footprint and lower requirements for power distribution, so the usage scenarios are more It is the most widely used and more suitable for private occasions. Because of this, almost every electric vehicle passenger car needs to be equipped with an on-board charger to meet the extensive AC charging needs of the public.
Under the current architecture of 400V and 600V voltage platforms for electric vehicles, the output power of on-board chargers is mostly 3.3kW and 6.6kW. In order to meet the charging demand under the 800V architecture, 11kW and 22kW on-board chargers have been developed and produced become mainstream power in the future.
With the explosive growth of the electric vehicle market in recent years, the market size of on-board chargers has also expanded rapidly. It is estimated that the market size of on-board chargers will reach 66 billion yuan in 2025, and the market prospect is broad.
Max Power New Energy Company has a unique strategic vision. As early as 2017, it has begun to lay out the electric vehicle on-board charger market. After more than ten years of development, it has become the top five exporters among domestic on-board charger manufacturers. The core products produced include on-board charger OBC, DC/DC converter and all-in-one integrated products with OBC and DC/DC as the core.
Due to its early start in the field of on-board chargers, Max Power New Energy has strong technical research and development advantages and rich industry experience, owns independent intellectual property rights on the core technology of on-board charging, and has first-class product quality. Therefore, it has been favored by many domestic and foreign OEM customers.
