Performance Analysis of Energy Regeneration System of Electric Vehicle with Two Wheels under the Mode of Constant Braking Torque

On the long straight road of one proving ground of Ministry of Communications, in order to study the influence of brake energy regeneration system (BERS), gear on coasting resistance, road coasting tests of a HEB were carried out under different conditions, separately on and off of BERS, neutral gear and gearing up. Test results showed, the regeneration brake force generated during the process of brake energy regeneration had quadratic relationship with vehicle speed, which had the greatest impact on coasting resistance; Coasting resistance under gearing up increased basically in proportion with rise in vehicle speed, and were about 2200N higher than those under neutral gear. When carrying out HEB road coasting tests, the BERS should be turned off, the transmission should be in neutral gear.

And Control

<span>Amidst the ever-increasing advancements in the technological realm-the electrical vehicle industry too has seen several leaps. This particularly owes to three primary factors one, the fact that we are running out of conventional resources like petrol and diesel; two, higher efficiency of electric vehicles; and finally, less pollution caused by them. This has led to a burgeoning in the use of BLDC motors with electronic commutation not only in EVs but also in industrial and commercial applications. This requires an enhanced driving and control mechanism to tap the efficiency that such motors provide to increase performance and to get better controllability and reliability. This paper presents a controller for this EV motor driver with increased efficiency by combining various strategies.</span>

Novel Design

In this paper, a novel design of an energy regeneration system was proposed for recovering as well as reusing potential energy in a boom cylinder. The proposed system included a hydraulic pump/motor and an electrical motor/generator. When the boom moved down, the energy regeneration components converted the hydraulic energy to electrical energy and stored in a battery. Then, the regenerated energy was reused at subsequent cycles. In addition, an energy management strategy has been designed based on discrete time-optimal control to guarantee position tracking performance and ensure component safety during the operation. To verify the effectiveness of the proposed system, a co-simulation (using MATLAB and AMESim) was carried out. Through the simulation results, the maximum energy regeneration efficiency could achieve up to 44%. Besides, the velocity and position of the boom cylinder achieved good performance with the proposed control strategy.
