There are two energy supply modes for energy vehicles: charging piles and swapping stations.
The charging pile is to directly charge the new energy vehicles to supplement the energy, and the power exchange is to centrally store and charge a large number of batteries through the centralized charging station, and at the same time, the battery replacement of the electric vehicle is directly completed in the battery distribution station.
With the increasing number of new energy vehicles, the charging-based power supply method is increasingly unable to meet market application requirements. Because the slow charging time of most car models is about 8 hours, and the battery replacement mode that can complete the battery replacement in a few minutes has great advantages, it has been mentioned as an effective way to supplement energy, and it is highly anticipated.
In the application of the battery replacement mode of new energy vehicles, the battery replacement connector is the only electrical interface of the battery pack, and it is necessary to provide a mixed connection of high voltage, low voltage, communication and grounding at the same time. In the process of rapid power exchange, there is an error in the coordination between the battery and the vehicle, and the power exchange connector needs to have floating compensation capability.
In addition, due to the high frequency of battery replacement, the battery replacement connector also needs to meet the requirements of high life and low maintenance cost.
The power-swap connector is expected to become the standard in the industry. On the one hand, the penetration rate of electric vehicles in the power-swap mode is increasing. Upgrading, maintenance and recycling.
After a large number of electric vehicle batteries are eliminated in the future, it is expected to enter the field of energy storage for secondary utilization, and the establishment of a unified connector interface standard has become the focus of the industry.
