1results about How to "Extend system life" patented technology

This invention relates to power management technology for new energy vehicles, and discloses an intelligent charging system and method for low-voltage batteries in new energy vehicles, comprising the following steps: S1. Real-time acquisition of operating data of the low-voltage battery and vehicle status data; S2. Calculation of the current state of health (SOH) of the low-voltage battery based on historical data; S3. Establishment and updating of a personalized power consumption behavior model for the vehicle, obtaining a load feature vector characterizing its idle power consumption mode; S4. Based on the current health state, the load feature vector, and the current voltage, prediction of the voltage change curve of the low-voltage battery over a future period using a voltage decay prediction model. Based on the load used by the low-voltage battery in different vehicles, a strategic charging solution is generated for the vehicle, while optimizing the energy flow management of the entire vehicle. By optimizing the timing of charging and proactive, predictive charging, the availability and efficiency of vehicle charging applications are improved.
