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.
This is 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 features "relatively low power and schedulable output" and "real-time grasp of electric vehicle battery data," which exactly match the core demands of resident scenarios.
All electric vehicle batteries need to be charged with direct current. 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. This means the loss of electric energy is borne by the user during the AC charging process, and by the charging operator during the DC charging process.
