For a typical battery, current, voltage and temperature sensors measure the following parameters, while also protecting the battery from damage: The current flowing into (when charging) or out of (when discharging) the battery. The pack voltage. The individual cell voltages. The temperature of the cells.
The electronic battery sensor is an important part of the vehicle energy management. The sensor informs the car of the exact battery status, measures the temperature and controls the charging voltage and charging current accordingly.
Intelligent Battery Sensor An IBS is a total measurement system for lead-acid battery management. These components measure the charge or discharge current flowing through the battery, the voltage across the battery terminals, as well as the temperature of the battery through thermal conduction between the battery post and the IBS unit itself.
If we design the signal conditioning circuit well, the shunt sensors are perfect current sensors for automotive battery systems. The other type of battery current sensor uses electromagnetic elements and measures the magnetic field of current. Therefore, by their nature, these types of current sensors are isolated.
The sensor also supports intelligent alternator control, which reduces CO2 emissions, saves fuel and protects the environment. If the battery no longer provides the desired performance, the system records a „defective battery“ and thanks to this early warning system, a plannable battery exchange is feasible.
Current flow in and out of a battery pack is a key parameter in any battery management system, hence the need for a current sensor. EV current sensors are basic components. They perform two major tasks. They help us to know how much energy we use. Also, the second task is avoiding overcurrents.
