 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...
