Liquid cooling also allows the battery pack to be operated with higher peak power loads because it dissipates more heat than other cooling methods. There are three main approaches to liquid cooling: serpentine ribbon-shaped cooling tubes, cooling plates with cooling channels inside them, and direct/immersive cooling.
