Electric vehicle shunts
In the world of electric and hybrid vehicles, automotive shunts are an indispensable star. This little guy is responsible for monitoring the current to ensure the safety and performance of the battery. In simple terms, it is the "eye" of the battery management system, always keeping an eye on the dynamic changes of the current.
The working principle of automotive shunts is actually not complicated. It is usually made of high-precision resistor materials, with low resistance, high precision, and high stability as its standard features. When current passes through the shunt, a voltage drop is generated across the resistor, and this voltage drop is proportional to the current. By collecting this voltage signal, the BMS system can calculate the current value and adjust the charging and discharging speed of the battery according to the current value.
When choosing an automotive shunt, there are several key factors to consider:
Accuracy: Accuracy is the lifeline of automotive shunts and determines the accuracy of current detection. Generally speaking, the accuracy of automotive shunts is required to be within 1%.
Temperature characteristics: The temperature of the vehicle working environment varies greatly, and the automotive shunt needs to have good temperature characteristics to ensure accuracy and stability at different temperatures.
Linearity: Linearity refers to the linear relationship between the output voltage and input current of the automotive shunt. In order to ensure the accuracy of current detection, the linearity of the automotive shunt is required to be high.
Reliability: The automotive shunt needs to have high reliability and be able to work stably for a long time in harsh working environments.
Installation convenience: The installation convenience of the automotive shunt is also one of the factors that need to be considered to facilitate installation and maintenance on the vehicle.
