An auto-regressive model for battery voltage prediction
The prevailing methods used in voltage prediction are the equivalent electrical circuit (EEC) models. EEC models account for the change in the voltage by a series of resistor capacitor networks to mimic the internal resistance of a battery. Thus, given a change in current the EEC models create an appropriate change in the voltage.
Introduction to Electric Vehicle Battery Systems
This limits the inrush current into all the large capacitors in the system and allows the battery management system to detect short circuits before the high-current path is completed. Isolation is continually monitored, usually on both sides of the main contactors, and a fault will occur if the isolation from either side of the high voltage ...

Constant current constant voltage charging algorithm
The Battery CC-CV block is charging and discharging the battery for 10 hours. The initial state of charge (SOC) is equal to 0.3. When the battery is charging, the current is constant until the battery reaches the maximum voltage and the current decreases to 0. When the battery is discharging, the model uses a constant current.
21.2: Electromotive Force
The voltage across the terminals of a battery, for example, is less than the emf when the battery supplies current, and it declines further as the battery is depleted or loaded down. However, if the device''s output voltage can be measured without drawing current, then output voltage will equal emf (even for a very depleted battery).
A Guide to Understanding Battery Specifications
• Terminal Voltage (V) – The voltage between the battery terminals with load applied. Terminal voltage varies with SOC and discharge/charge current. • Open-circuit voltage (V) – The voltage between the battery terminals with no load applied. The open-circuit voltage depends on the battery state of charge, increasing with state of charge.
