Charging Pile

Charging pile scheme based on Infineon TC233LP

Due to the practical needs of electric vehicles in energy saving and emission reduction and the medium and long-term situation that fossil energy is facing depletion, many automobile manufacturers at home and abroad are actively studying and promoting electric vehicles, and the pressure on China's energy structure and environmental governance has promoted the recent structural adjustment policies of the automobile industry. As soon as the policy is issued, ten thousand horses gallop. At present, more than a dozen electric vehicle manufacturers such as BYD, Chery, Zhongtai and Foton have produced electric vehicles. Other manufacturers have also launched electric vehicle products at the end of 2010 or the beginning of 2011. Meanwhile, foreign and joint-venture electric vehicles have also launched new energy batteries with excellent performance and fashionable appearance to seize the Chinese market.

Therefore, the 6kW off vehicle charger scheme based on Infineon tc233 + ipw65r041cfd power device is introduced. It is mainly used in off-board charging of pure electric vehicles or hybrid electric vehicles. The main architecture adopts PFC + LLC architecture, and the standard CAN bus design is adopted in the control and communication part, which can communicate with the vehicle in real time. The output voltage and current of the charger can be controlled through can, and the current working state of the charger can be read.
