According to this scheme, a 2kW vehicle charger is designed. The charging mode adopts three-stage charging method to charge lithium battery pack, and the three-stage charging is simulated. The results are consistent with the requirements of three-stage charging curve. 1. Introduction
Charging loss is another important factor during charging. Reducing the charging loss increases the charge efficiency. Here, we extend the cost function in the fast-charging strategy to include the penalty for charge energy loss. Dynamic programming is used to trade off between charging time and charging loss.
With a physics-based battery model, a multi-objective optimal control problem is proposed to investigate the charging strategies that optimally trade off the temperature rise, charging time, and loss. First, a fast-charging strategy (minimum time) with the sole purpose of reducing charging time is presented and experimentally validated.
The battery management system sends the measured charging voltage V, charging current I, maximum and minimum temperature of the battery pack to the charger. The vehicle charger monitors the whole charging process according to the state of battery charging. The flow chart of three-stage charging subroutine of charger is shown in Figure 4. Figure 4.
The proposed framework has achieved an excellent balanced charging performance. To implement the framework in real applications, such as EV battery fast charging, more realistic boundary conditions and thermal interactions with surroundings would need to be implemented in the model.
The fast-charging strategy is developed with the sole purpose of reducing charging time. For the fast-charging strategy optimization, the cost function includes only charging time (i.e., weighting factors \ (\alpha = 1\) and \ (\beta = \gamma = 0\)) as follows:
Charging speed depends on your vehicle''s technology and the infrastructure. No charge point can charge a car faster than the EV''s charging rate allows. For example, if the vehicle''s maximum …
