Although the manually adjustable resistor inevitably introduces resistive power losses, its use should not be interpreted as a practical commercial solution. Instead, it represents a proof-of-concept implementation that enables systematic investigation of charging-current regulation under controlled experimental conditions. This experimental methodology provides valuable information regarding the relationship between charging current and regenerative braking efficiency before implementing electronically controlled charging-current regulation techniques.

Comparison between MATLAB simulations and real driving experiments indicates good agreement between theoretical predictions and experimental observations. The relatively small deviation demonstrates that the developed simulation model adequately represents the dynamic behaviour of the proposed regenerative braking system.

Overall, the proposed regenerative braking strategy demonstrates that charging-current regulation constitutes an important design parameter for improving regenerative braking performance in light electric vehicles while maintaining low hardware complexity and implementation cost.
