Battery capacity display system of lithium battery pack based on virtual instrument

According to the type and number of lithium battery used in our project, electrical vehicle lithium battery management system (BMS), and the environment which the virtual instrument will be used, the sampling circuits are designed, including cell voltage, battery pack voltage and temperature. Then PC is used to develop the virtual instrument interface. Through java script, more dynamic effects are added to it. In the test, the beautiful and striking virtual interface could dynamically display the state of battery, voltage, current, temperature, error and warning. It shows that the virtual instrumentation system can display important information of battery dynamically and visually in real-time, achieving the expected goal. All these will be supplied to driver for whom to choose a suitable driving strategy.
