It's a crucial part of any system that relies on batteries, helping engineers and users keep tabs on power consumption and ensure the system operates optimally. In a battery system, battery current sensors have two jobs: safety and accuracy. The primary job is safety, ensuring the battery operates within safe current limits to prevent damage.
In addition to safety, battery current sensors contribute to the accuracy and integrity of the entire system. For instance, in electric mobility, a battery is an integral part of a system, and its current sensor acts as a check to ensure that other components, such as motor controllers, are working correctly.
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.
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.
A current sensor is an essential device used in management and power calculation-based applications. It helps measure the flow of current in a circuit or a device and generates a suitable signal proportional to the measured current, typically an analog voltage.
When the battery is the main source of energy for systems in HEVs/EVs, it is essential to have information about its charging and discharging cycles. Current sensors are the main source of information for charging and discharging cycle information by reporting the status of battery SOH to the battery management system.
