In the future, private cars will become the main force in electric vehicle ownership. With the construction of electric vehicle charging infrastructure, compared with large public charging stations, residential charging stations such as residential communities and industrial parks will gradually become the mainstay of private car charging. Main scene.
This is also the natural soil for low-power DC charging. Due to the resident charging scenario, its outstanding features are tight power capacity, long charging time, and high safety requirements. Low-power DC charging has the characteristics of "relatively low power and schedulable output." , real-time grasp of electric vehicle battery data" and other features, which exactly match the core demands of the resident scenario.
All electric vehicle batteries need to be charged with direct current, that is, no matter which method is used, the alternating current needs to be rectified into direct current to charge the electric vehicle.
The essential difference between AC charging and DC charging is that the AC charging rectification process is realized by the on-board charger (OBC) of the electric vehicle, while DC charging is realized by the charging pile, which means that the rectification process brings The loss of electric energy is borne by the user during the AC charging proces
s, and by the charging operator during the DC charging process.
