A battery current sensor is a critical component in electrical systems. It is crucial in measuring current and monitoring energy flow within a battery or an electrical circuit. These sensors typically utilize specific technologies to measure the current, and their primary function is to ensure safe and efficient operation.
If you're able to accurately sense the current draw, and the battery is well-characterized, you'll be able to accurately determine the amount of time remaining before your mission-critical system dies. With careful design, you can measure battery current to within 0.2 percent of full scale.
As shown in Figure 1, there are two main locations where you can measure current: top of stack (high-side sensing) and bottom of stack (low-side sensing). Figure 1. Top of Stack vs. Bottom of Stack in a Battery Management System
Measuring the voltage drop across a low-side current-shunt resistor is often the simplest method to determine battery/load current. Figure 2 shows an example low-side current-sensing circuit using the TLV379. The circuit in Figure 2 was designed to create a 0V-1.2V output voltage for a 0A-1A load current, i LOAD.
Battery pack voltage, using a high-voltage resistor divider. Shunt temperature, using a thermistor. Auxiliary measurements, such as the supply voltage, for diagnostic purposes. As demand for batteries to store energy continues to increase, the need for accurate battery pack current, voltage, and temperature measurements becomes even more important.
There are a variety of current sensing technologies that can monitor the status of an HEV or EV battery. The solution varies with the voltage and capacity of the battery. As shown in Figure 1, there are two main locations where you can measure current: top of stack (high-side sensing) and bottom of stack (low-side sensing). Figure 1.
With careful design, you can measure battery current to within 0.2 percent of full scale. With that information, the most accurate gauging systems, taking battery age, temperature, self-discharge, and discharge-charge cycle history into account, can usually estimate remaining battery life to within 1 percent.
