Intelligent temperature compensation for energy storage batteries

What is the relationship between battery thermal management and energy management?

1. The electrical-thermal-aging coupling relationship between battery thermal management and energy management is systematically characterized. 2. The proposed hierarchical MH-MPC concurrently optimizes battery capacity loss cost and battery cooling cost through proper decoupling. 3.

What is battery thermal management system?

In the battery thermal management system, the electrical power is consumed by the compressor, pump, and fan. Fig. 1. Hybrid energy storage system and battery thermal management system in the studied electric vehicle. 2.1. System modeling 2.1.1. EV model

Does integrated battery thermal and energy management need a hierarchical method?

For the battery SoC, the proposed hierarchical method is also a bit lower than centralized MH-MPC and about 3% lower than Method 1. These all indicate the necessity of integrated battery thermal and energy management using the hierarchical method. Finally, the numerical results are summarized in Table 1.

Should a battery temperature penalty be included in deep Q-learning?

By adding a battery temperature penalty term into the cost functions of deep Q-learning and Actor-Critic deep reinforcement learning , the battery temperature can be well limited below the upper bound, ensuring battery thermal safety and minimizing energy loss.

How does battery cooling affect energy management?

For electric vehicles with battery/supercapacitor hybrid energy storage system, battery cooling is deeply coupled with load power split from the electrical-thermal-aging perspective, leading to challenging thermal and energy management issues.

What is the upper-level battery thermal optimization problem?

In this way, the upper-level battery thermal optimization problem is significantly simplified: the supercapacitor-related constraints and state iteration are removed. Also, the battery current constraint is removed since the energy management will determine the actual battery current.
