You should be referring to the fast charging conditions of new energy electric vehicles. If yes, you must first confirm that the electric vehicle has a fast charging port, that is, the car's power battery allows for fast charging, the manufacturer has carried out a variety of tests on the battery characteristics of the configuration, including slow charging or fast charging, and added the corresponding protection function, when the charging pile is connected to the need for fast charging instructions, If the internal set fast charging conditions are met, the permit signal is sent to the charging pile.
The second condition is that the charging pile used belongs to the fast charging pile, that is, the DC charging pile, which determines the charging power that can be issued to the vehicle battery system according to the instructions sent by the vehicle battery management system. When the piles meet the requirements of each other, the charging process officially begins, and the charging pile will automatically disconnect the charging process after receiving the stop charging instruction.
As the name suggests, fast charging can charge the power to about 80% in a short period of time, the current of the fast charging mode is generally 150 ~ 400A, the charging power is greater than 50kW, but the fast charging has a great impact on the car battery in a short period of time, there may be a phenomenon of battery fever, and the owner needs to do a good job in the heat dissipation of the battery when fast charging. Fast charging is also known as emergency charging, so unless special circumstances, it is not recommended that the owner frequently use fast charging to replenish the power.
