Ioniq 5 Battery Pack Analysis: DEEP DIVE

Let's go on a DEEP DIVE of the Hyundai Ioniq 5's battery pack! We discuss the battery modules, thermal management system, location of temperature sensors, and why the Ioniq 5 rapidgates (charge slowly due to battery overheating) under certain conditions. These findings should also apply to the EV6 and potentially the Ioniq 6 and EV7.
