 For electric vehicles at this stage, increasing the range and making long-distance electric vehicles is the main development path. When the battery cost is reduced and the cumulative range reaches 500-600 km, the main conflict of electric vehicles will change from mileage anxiety to charging anxiety. Improving the charging power of electric vehicles mainly includes several core elements. We can only go two ways: In our practical design considerations, the temperature of the entire connection point needs to be kept below 100 degrees. The main reason for this is that exceeding a temperature will make the corrosion resistant coating of the conductor unstable. Temperature rise problems similar to those caused by the contact and crimp resistance of the charging cable and connector below can occur inside the battery as we described above. If they occur at the battery connections, they can have a significant impact on the battery. First path variation: Because under this path we can also...

 As is often the case with every new technology, the beginning is difficult and full of competitive standards. Each manufacturer uses and develops its own standards and processes. Only time can decide who will win. This is true for mobile phone charging connectors, and now for electric vehicle charging cable connectors. Let's look at all the charging connectors in the world now. For simplicity, different types of connectors can be roughly divided according to the regions where they are most used. Although this is a simplified statement. The AC charging station usually has no integrated charging line, so the driver carries the charging line suitable for his car, and the problem of connector type is basically eliminated. For safety reasons, current volume, cable price and weight, DC fast charging station is always attached with cables. Therefore, it is necessary to select sites with appropriate connectors. AC connector: The first batch of electric vehicles, such as GM EV1, used induc...
