What are the characteristics of electric vehicle charging connectors applied in charging pile equipment

1. Power battery characteristics
Electric vehicle charging connectors have different charging characteristics in different types of power batteries, and the best charging rate varies between 0.2 and 2.0C. In the case of the same rated voltage of the battery system, the maximum charging voltage also reflects a certain difference due to the difference in the type and structure of the battery. For different kinds of batteries, charging methods and charging control strategies are also different, and different charging methods should be used according to their different battery characteristics.
2. Charging time
Electric vehicle charging connectors put forward different requirements for charging time in electric vehicles with different operating modes, and different charging times require different charging methods to meet them. In the case that the charging time of electric vehicles is not high, conventional charging can be carried out by using the power trough during the shutdown time to extend the driving range of the vehicle; In the case of more urgent charging time, it is necessary to use fast charging or quick replacement of battery pack to achieve timely energy supplement.
3. Charging place and other environmental conditions
The charging and discharging efficiency of the electric vehicle charging connector in the power battery is affected by the charging site and other environmental conditions, especially by the ambient temperature. At room temperature, the battery charge acceptance is strong, and the charge acceptance gradually decreases with the decrease of the ambient temperature. Therefore, as the ambient temperature decreases, the power demand of the charging station will increase. Therefore, the construction of charging stations should ensure that their environment is not affected by man-made temperature conditions as much as possible.
