Alerts

Signal Name Description Condition Impact Important
The battery management system (BMS) detects that the high voltage processor (HVP) configuration doesn't match.
The BMS detects an HVP configuration that does not match the expected configuration.
Inability to charge, drive, or support the low voltage (LV) system
No
The battery management system (BMS) detects a large calculated amp-hour capacity (CAC) update.
The BMS detects a change in CAC above the limit threshold.
This alert is primarily informational.
No
The battery management system (BMS) detects that the high voltage (HV) isolation contactor closed below the warning threshold.
The BMS detects that the HV isolation was below the warning threshold when pack contactors closed.
This alert indicates that HV isolation is low, but above the sufficient level for vehicle operation.
No
The battery management system (BMS) detected a condition that indicates a BMB device fault.
Any BMB device in the daisy chain reports any of the monitored fault indicators.
This alert is primarily informational, and may indicate a potential BMB hardware failure that results in unreliable measurement data.
No
The battery management system (BMS) has detected a mismatch between the pack voltage and DC Link voltage.
The battery management system (BMS) has detected a mismatch between the pack voltage and DC Link voltage.
Inability to charge, drive, or support the low voltage (LV) system
No
The Battery Management System (BMS) has detected one or more module temperatures exceed the warning threshold.
The maximum module temperature is greater than the warning threshold.
Vehicle performance is limited.
No
An uncorrectable error has been detected in the OTP (one-time programmable) memory for a battery monitoring board (BMB) device.
Any BMB device reports an uncorrectable error in the OTP memory.
This alert is primarily informational and is used for logging purposes. BMB device behavior may be impacted.
No
A bleed Field-Effect Transistor (FET) on the Battery Management Board (BMB) is not operating as designed. This will prevent the battery from balancing the brick by decreasing the brick voltage.
Upon a periodic wake, after an ECU reset, or every 6 hours, the Battery Management System (BMS) will test all bleed switches by switching them on in turn. If the sensed brick voltage does not significantly change, this alert is set.
The bleed FET will prevent the battery from properly balancing the brick by bleeding the voltage down. There is a decrease in available energy to the vehicle potentially leading to decreased range.
No
The battery management system (BMS) has detected a high voltage sense harness (VSH) impedance.
The BMS detects a VSH impedance value above the threshold.
Inability to charge, drive, or support the low voltage (LV) system
No
The battery management system (BMS) detects that the shunt is missing (MIA).
The BMS does not receive one or more expected CAN messages from the shunt.
Inability to charge, drive, or support the low voltage (LV) system
No
The Gateway packPerformanceDeviation config does not match the configured pack type.
GTW_packPerformanceDeviation is not compatible with the configured pack type.
This alert may indicate an incorrect config block, or that the installed pack is incompatible with the car config.
No
The battery management system (BMS) detects that the high voltage (HV) battery config block does not match the configuration of the vehicle.
GTW_packEnergy is not compatible with the configured pack type.
This alert may indicate either an incorrect config block, or that the installed pack is incompatible with the car configuration.
No
Battery pack 3 has pack voltage too low to allow dcdc support.
Battery pack 3 has pack voltage below the voltage too low set threshold
LV support may be blocked
No
The battery management system (BMS) has detected that at least one flood port is open.
The BMS detects that voltage of the flood port switch sensor indicates that one or more flood ports is open.
This alert is primarily informational and used for logging purposes.
No
The battery management system (BMS) has prevented pack contactors from closing due to one or more other alerts.
One more BMS alerts that prevents pack contactors from closing is present.
Inability to charge, drive, or support the low voltage (LV) system
No
The maximum charge level of the high voltage (HV) battery is exceeded.
One or more battery management system (BMS) alerts that reduce the maximum charge limit are set, and the instantaneous charge level is higher than that limit.
Vehicle will not be able to charge if connected to a power source, as the reduced maximum HV battery charge level is exceeded.
No
The battery management system (BMS) detects that the high voltage (HV) battery is not charging enough while in a charging state.
The BMS detects that the HV pack has been discharged to below the set threshold while charging.
Inability to charge
No
The battery management system (BMS) has detected a condition that prevents it from disabling the charge session.
The HV battery is charging and the BMS detects a condition that prevents it from disabling the charge session.
This alert is primarily informational and used for logging purposes.
No
The maximum charge level of the battery is limited by one or more alerts.
One or more battery management system (BMS) alerts that reduce the maximum charge limit are set.
Maximum charge is reduced.
No
The battery management system (BMS) cannot transition into the requested state because of a blocking condition.
A blocking condition does not allow the BMS to transition into the requested state.
Inability to charge, drive, or support the low voltage (LV) system
No
