Systems and methods for monitoring a state of health of a battery system of an electric vehicle

A method for monitoring a state of health (SOH) of a battery system of an electric vehicle (EV) comprising:

• generating a projected SOH value of a battery system of the EV at one of a future vehicle age and a future total EV mileage, wherein:
• the projected SOH value of the battery system is based on a current SOH value of the battery system and historical SOH values of the battery system;
• the current SOH value of the battery system and the historical SOH values of the battery system are based at least in part on use of the battery system to supply power to at least one of an offboard vehicle load and an onboard accessory load;
• determining whether the projected SOH value of the battery system is less than a SOH threshold at the one of the future vehicle age and the future total EV mileage;
• and
• generating a customer SOH alert associated with limitations in connection with the use of the battery system to supply power to the at least one of the offboard vehicle load and the onboard accessory load for display on a display device of the EV based on the determination.

An electric vehicle (EV) comprising:

• at least one processor;
• and
• at least one memory communicatively coupled to the at least one processor, the at least one memory comprising instructions that upon execution by the at least one processor, cause the at least one processor to:
• generate a projected SOH value of a battery system of the EV at one of a future vehicle age and a future total EV mileage, wherein:
• the projected SOH value of the battery system is based on a current SOH value of the battery system and historical SOH values of the battery system;
• the current SOH value of the battery system and the historical SOH values of the battery system are based at least in part on use of the battery system to supply power to at least one of an offboard vehicle load and an onboard accessory load;
• determine whether the projected SOH value of the battery system is less than a SOH threshold at the one of the future vehicle age and the future total EV mileage;
• and
• generate a customer SOH alert associated with limitations in connection with the use of the battery system to supply power to the at least one of the offboard vehicle load and the onboard accessory load for display on a display device of the EV based on the determination.
