The battery pack in the article is sized with a nominal voltage of 363 V. It is composed of 110 single cells, connected in series, using lithium-iron-phosphate (LFP) technology.
The pack voltage can be determined by calculating it from the individual cell voltages rather than measured by the total pack voltage sensor. The BMS can be set up to ignore any difference in voltage between the two methods.
In the context of a BMS, a total pack voltage sensor is used to provide the BMS with a measurement of the total voltage of the battery pack. In versions of the firmware 2.6.5 and prior, the voltage measured by the total pack voltage sensor is used for enforcing the minimum and maximum pack voltage limits.
However, when I measure the voltage across the BMS P- cable and the Battery Pack's positive terminal, I am only getting 47V even though the pack measures 58V. I read that the BMS output is supposed to match the pack output, but can't think of anything I did wrong.
In Orion BMS Version 1.7.x, go to the General Settings tab and check the box next to "Disable Total Pack Voltage Sensor". Set the "Pack Voltage mismatch Threshold" to 650 volts. In Version 1.8.1, under the "Fault Settings" tab, select the line that says "Ignore pack voltage mismatch fault condition" to disable the pack voltage sensor.
In the context of a battery system, a Battery Management System (BMS) manages, protects, and balances the battery pack. A total pack voltage sensor is a component within the BMS that provides the system with a measurement of the total voltage of the battery pack.

low voltage problem but good alternator and battery?
This maximizes charging system efficiency by reducing voltage output when higher voltages are not required. The GM regulated voltage control system can vary from 11.5 -15.5 volts. As with other systems in use today, the GM system has a fuel economy mode, which is designed to lower the charging system voltage by reducing the alternator field strength.
