How does a BMS measure a battery pack?
Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode. A method called Coulomb counting uses these measured currents to calculate the SoC and SoH of the battery pack. The magnitude of currents during charging and discharging modes could be drastically different by one or two orders of magnitude.
How does a BMS measure bidirectional battery pack current?
Therefore, in discharging mode, current flows in the opposite direction from charging mode, out of the HV+ terminal. Generally, a BMS measures bidirectional battery pack current both in charging mode and discharging mode. A method called Coulomb counting uses these measured currents to calculate the SoC and SoH of the battery pack.
What is a battery management system (BMS) in electric vehicles?
Input voltage, current, and temperature measurement circuits are the vital concerns of a Battery Management System (BMS) in electric vehicles. There are several approaches proposed to analyze the parameters of voltage, current, and temperature of a battery. This paper proposes a BMS methodology that is designed using linear optocouplers.
Why do EV batteries need a BMS?
A battery (lithium ion battery) used in an EV deteriorates every time the battery discharges or is charged. These cycles of battery deterioration may lead to a drop in the vehicle performance. The BMS is an important solution to this problem.
How to measure current in a BMS?
In order to measure current, we must measure the voltage through a resistor, and then we can infer what the current is. There are 2 basic methods to monitor current in a BMS. The 2 methods are using a resistive shunt or using a Hall-effect mechanism.
Can a battery management system monitor electrical current?
Battery management systems must not only monitor temperature and voltage but must also monitor current in its system. It must be able to ensure that excessive amounts of current are not flowing through the system. They're required to log abuse conditions. In order to monitor electrical current through a BMS, we cannot measure current directly.
