6.6KW lithium battery OBC 48V

Brief Introduction

An 6.6KW lithium battery OBC 48V is an electric vehicle component that handles the task of charging the vehicle's battery from the mains power supply. The6.6KW lithium battery OBC 48V is a high efficient AC to DC converter design for electric car charging. And it is possible to use two or more obc 6.6kw 48v charger in parallel to get higher AC charging power; Each of them is controlled by a separate CAN message to achieve a simple, fast and safe charging topology.

Development Trends and Challenges of OBC

OBC is an important component of BEV and PHEV. As the number of electric vehicles increases, the number of vehicles equipped with OBC will also increase. At the same time, more and more electric vehicles will also be equipped with DC fast charging function.
OBC will adapt to 800V high-voltage platform.
 

As the 800V high-voltage platform becomes more and more popular, and in order to charge batteries with larger capacity, we need to provide OBC with higher output power. In the future, OBC needs to have these characteristics: "high voltage (high withstand voltage)", "high current", "low loss", "high heat resistance" and "small size".
OBC needs to have the ability of bidirectional charging.
OBC can convert the DC power of the high-voltage battery pack into AC power to support the operation of external AC loads.
Discrete high-voltage components will be widely used in OBC.
The trend of fast charging will greatly increase the power required for OBC topology.
New OBC tends to be high power (11-22kW). This development trend is coupled with the demand for low system cost, high efficiency and high power density.
