Circuit/System Description

The X98 Hybrid/EV Battery Charger Coupler contains up to 4 temperature sensors for the AC Charging terminals (Region specific). In Regions with single phase AC charging there is a sensor for Line 1 and for the Neutral terminals. In Regions with 3 phase AC charging there are additional sensors for Line 2 and Line 3 terminals. In order to diagnose issues with the sensors, the K16 A Battery Energy Control Module 1 compares values between the temperature sensors to determine if there are any issues with the X98 Hybrid/EV Battery Charger Coupler. If the K16 A Battery Energy Control Module 1 detects an issue, such as overheating, it may disable AC charging when the DTC set or may derate charging just prior to DTC setting.
