An innovative approach to battery management and propulsion system of electric/hybrid electric vehicle

The life span, efficiency and safety of lithium-ion batteries can be enhanced by temperature reduction and heat transfer optimization. The current research focuses on the cooling of lithium-ion batteries by reducing their temperature with optimized aluminum plates, which act like fins and carry away the heat due to convection in between the cells. For that, a seven cell battery pack model was built and cooling was done with air as a medium, which was manually passed through the system at a specified velocity using a blower. Considering the safety and cost as a key factors, dummy cells made of aluminum plates with heating coils inside were used rather than the original Li-ion battery for experimental studies. Numerical investigation of the temperature distribution on fins and the factors affecting the temperature reduction were performed. Free convection and forced convection methods were considered for the model using various calculated film coefficients. A reduction of 10oC to 20oC in temperature can be achieved using air which flows at a velocity of 8.5m/s. Numerical results are compared with the experimental results and the differences are discussed.

“…Based on the results, single wall carbon nano tubes may clearly be utilized in advanced cooling applications. In electric and hybrid electric cars [22], battery management and propulsion systems are critical. The results showed that only in the constant power area will the main acceleration be detected with a minimum power rating.…”

“…About 370 million tons of FA are produced annually globally [1] and its disposal represents a serious ecological problem [1][2][3][4]. Previous studies [5][6][7][8][9][10] have shown that by using FA as a reinforcement in the matrix based on aluminum and its alloys, a composite with lower density with properties same or better than the base material can be obtained. Properties of such composite materials can be further improved by applying a plastic deformation treatment process [11][12][13].…”

This paper describes the influence of deformation by equal-channel angular pressing (ECAP) on the solid particle erosion resistance of the AlSi7Mg0.3 alloy and AlSi7Mg0.3 based composite material reinforced with the addition of 4 % of fly ash (FA) particles. Both, alloy and composite samples were produced using the compo-casting method. The samples have been subjected to ECAP in multiple passes with the rotation of samples around the vertical axis for the angle of 90° after each pass. Particles of silicon carbide (SiC) have been used as erodent while their impact angle was varied (30° and 90°). Observed samples of AlSi7Mg0.3 alloy generally showed higher wear resistance at 90° angle where material fatigue predominates, than at a 30° angle where abrasion-related phenomena predominate. On the other hand, AlSi7Mg0.3 based composite material exhibited erosion wear at 30° angle less than at 90° angle after one ECAP pass. Evaluation of the erosion resistance has been made based on mass and volume loss. After two passes of ECAP, the matrix structure of the AlSi7Mg0.3 based composite material, as well as that of the AlSi7Mg0.3 alloy was improved from the aspect of erosion resistance.

“…Different types of electric vehicles such as hybrid electric vehicles (HEVs) [13,14] and plug-in electric vehicles (PEVs) [15] also produce little emission of pollutants due to their energy saving ability [16]. Different ways of battery power management are evident in different types of electric vehicles.…”

“…Different ways of battery power management are evident in different types of electric vehicles. The battery electric vehicle (BEV) can be used on the roads until the battery is discharged and PEV batteries can be charged by taking power from the electric supply of the house [16]. Even though plug-in hybrid vehicles (PHEVs) can be operated in full-electric mode and offer improved energy efficiency without deteriorating performance, PHEVs pose challenges to find a solution regarding power management optimization [17].…”

This paper presents a new approach to improving the battery performance and its longevity by the implementation of torque sensor pedal technology on the developed electric triwheeler vehicle (i.e., wheelchair). The paper has also discussed integration of the torque sensor technology with the overall electrical system of the vehicle. Incorporating the components of torque sensor technology reduces the human effort immensely by providing assistance from the battery bank to drive a hub motor while maneuvering the wheelchair using the torque sensor pedal. Field tests were carried out in three different stages, one with pedal, one with the throttle only, and with varying the load on the wheelchair, to distinguish the effect of load test on battery performance using the pedal. Results of the field tests reveal that the state of charge of batteries has been minimized using the pedal due to the contribution of the muscular energy of the user along with the battery energy to meet the total energy demand of the motor. Analyzing test results with the torque sensor pedal clarifies that the vehicle covers a longer distance, lessens power dissipation from the batteries, and reduces energy consumption from the batteries, which leads to improvement of the battery performance and its longevity ensuring sustainability of the electric vehicle.
