Nowadays, for electric vehicles, increasing the cruising range and making long-lasting electric vehicles is the main development path. When the battery cost drops and the combined cruising range reaches 500-600 kilometers, the main contradiction of electric vehicles will change from range anxiety to charging anxiety. Improving the charging power of electric vehicles mainly includes several core elements. The following are the main methods for analyzing the reasons:

1: Increase the current: If we keep other components unchanged and choose the path to increase the current, the main limitation is the heat loss caused by the large current, which will cause the overall design to be very different. High currents in a circuit create high heat losses, since the resistance of all components (connectors, cables, electrical connections to the battery, busbars, etc.) inevitably heats up. If the battery overheats during charging, these heat losses need to be taken into account when designing and sizing the conductive elements to avoid problems such as overloading, overheating, or controlled derating of the charging current.

2: Increase the voltage: Since the above-mentioned increase in current is limited, the current-limiting current is generally defined as 500A, and the achievable power is around 200kW. Increasing the voltage to switch the 400V system to 800V becomes an option. This is a systematic improvement of all electrical components. There were changes to the core switchgear and other parts.

Let's take a closer look at some of the issues to consider on a path that's accessible both ways. If you need to know more about high-power cable products for electric vehicles, please visit: https://www.omgevcable.com
