BMS_a177 — SW Energy Buffer Size

Full alert identifier: BMS_a177_SW_Energy_Buffer_Size

Alert description

The Battery Management System (BMS) energy buffer is greater than the acceptable threshold. This results in an inaccurate range estimate.

Potential impact

A large energy buffer results in an inaccurate battery State of Charge (SOC) estimation causing a poor range estimate.

Set condition

The BMS energy buffer is greater than the acceptable threshold.

Clear condition

The BMS energy buffer is within the acceptable threshold. The buffer can be reduced by charging the vehicle to 100%.
