Jiangling Motors Corporation has applied for a patent for an energy management system aimed at plug-in hybrid vehicles, addressing the inefficiencies of current energy management solutions. According to information from the National Intellectual Property Administration, the patent titled “Energy Management Method and System for Plug-in Hybrid Vehicles” was filed on March 2025 with the publication number CN119975321A.
The patent summary reveals that the invention introduces a method and system for energy management in plug-in hybrid vehicles. This method includes real-time collection of multidimensional data during vehicle operation, which is used to determine the vehicle’s actual power demand. Additionally, it calculates the predicted power demand based on the current throttle opening rate.
To optimize performance, the method establishes an objective function composed of fuel economy, battery health, and power responsiveness. It employs a model predictive control algorithm to solve this objective function over a rolling time horizon, resulting in the torque distribution between the engine and electric motor. The torque allocated to both the engine and motor is then used to control the vehicle.
This innovation aims to resolve the challenges associated with the poor energy management performance of existing plug-in hybrid vehicles.
According to data from Tianyancha, Jiangling Motors Corporation, founded in 1997 and located in Nanchang, primarily engages in the automotive manufacturing industry. The company has a registered capital of 863.214 million RMB. Additionally, it has invested in 9 companies, participated in 1636 bidding projects, and possesses 851 trademark records and 4677 patent records, along with 661 administrative licenses.
