Embodiment Construction
[0027] The present invention is based on the hardware-in-the-loop simulation platform of xPC Target, and estimates the state of charge of the solid power battery; the specific steps are as follows:
[0028] a. Data collection part: collect the current, voltage and temperature parameters of the battery through current sensors, voltage sensors and temperature sensors, and use hardware filters to filter the collected data;
[0029] b. Target machine: The filtered signal is input to the real-time kernel of the target machine through the AD board for processing. The real-time kernel obtains the current, voltage and temperature information of the battery, and processes the data according to the downloaded model to obtain the charge of the lithium-ion battery. Status value; and then display various parameters and estimation results of the battery in real time according to the needs, and transmit the collected data and processed data to the host for storage for post-processing;
