The state-of-charge (SOC) estimation approaches based on the pack model can hardly provide precise estimation due to cell difference, while the approaches based on each cell cost high computation resource, which are not suitable for real-time application. The estimation error can be further enlarged without considering balancing current. The SOC estimation approach of the battery pack considering...
The electromagnetic environment of the lithium-ion battery in the Electric Vehicles (EVs) is severe. Moreover, the load current of the battery in the EVs changes drastically and randomly depending on the EV driving condition. As a result, the voltage and current signals measured by the Battery Management System (BMS) normally contain the noise such as the white noise. This results in the estimation...
The System is made up of MCU and GSM Modem. It will display the alarm content in Chinese directly at your mobile screen, and it recurs to the most reliable GSM mobile network. The system adopted initiative infrared sensor to detect, and it turned the traditional alarm net and alarm windows to immateriality. Besides, the system equipped the smog sensor and leakiness sensor of gas and guarded against...
