Though electric vehicles have the benefits of zero tailpipe emissions and convenient overnight charging, other challenges remain such as limited driving ranges, slow refueling while on-the-go, lithium supply issues, and emissions from some sources of electricity generation (e.g., coal). Fuel cell powered vehicles address the refueling time issue, which will also ease range concerns if hydrogen fueling stations are available. Furthermore, on-board solar generation can replace a portion of the vehicle’s grid charging needs and extend driving range. For both options, a smaller battery could be used, meaning less lithium is required. However, the power electronic architecture for such a solar fuel cell range extended vehicle (S-FCREV) would be complex and costly with conventional separate converters. Thus, this paper proposes the first practical multi-port converter that can perform all S-FCREV requirements with a low …

Diesel-based vehicles are prevalent in underground mines all over the world; however, an electric revolution is beginning to unfold in the mining industry. Mines operating with diesel fleets require extensive ventilation due to toxic gas and heat emissions from diesel engines, and these ventilation costs increase as mines continue to dig deeper for depleting resources. Electric mining vehicles have zero emissions and emit less heat, meaning ventilation costs decrease. Furthermore, unlike diesel trucks, electric trucks can capture regenerative braking energy on downhill segments. Recent battery advancements have allowed electric mining trucks to become cost-competitive with their diesel counterparts when all system-level advantages are considered. However, there is presently a lack of knowledge in designing an optimal electric mining fleet and charging infrastructure, compared to the many decades of “best …

Recent advancements in high-efficiency flexible thin-film solar cells make it possible for solar-charged electric vehicles to obtain ample solar energy from on-board photovoltaic (PV) cells. To maximize the on-board solar energy generation while driving and parked even under partial shading conditions, this paper demonstrates the necessity of the optimization of the PV interconnections and proposes an optimization method using Genetic Algorithm. Using solar radiation data, modeled partial shading data, and temperature profiles of Los Angeles (LA) to run simulations in MATLAB/Simulink, this research shows the monthly and annual accumulated on-board solar energy comparison between the optimized PV interconnection and an unoptimized design, and demonstrates that an annual 3% more on-board solar energy could be accumulated in LA with the proposed PV interconnection optimization method.

A Space Vector Modulation-Based Sinusoidal Current Control Strategy for the Three-Phase Dual Active Bridge Converter

In most electric vehicles, there is a high-voltage system of around 200-450V to power the drive train and a low-voltage system to power the low-voltage loads. The three-phase DAB (3P-DAB) converter is one potential bidirectional topology that can be used to connect the two systems, due to its characteristics of inherent soft-switching and high-power density. A commonly used modulation scheme for the 3P-DAB converter is single phase-shift (SPS) modulation. On this basis, several modulation schemes have been proposed to extend the soft-switching range and minimize the conduction losses. However, almost all of the existing modulation schemes for the 3P-DAB are achieved by adjusting the phase-shift angle and duty cycle. Considering that the 3P-DAB converter is comprised of two three-phase two-level converters, space vector modulation (SVM) can also modulate the 3P-DAB converter, which can help to …

The duty-cycle control (DCC) modulation scheme for the three-phase dual-active-bridge (3p-DAB) dc–dc converter is a promising three degree-of-freedom modulation scheme which can extend the converter's soft-switching range and reduce conduction losses under partial loading and wide voltage variations. However, the prior suggested methods to implement DCC in 3p-DABs have drawbacks, such as requiring a multifrequency approximation and offline optimization process, or achieving less than optimal efficiency. To overcome these challenges, this article first proposes an optimal DCC modulation strategy (OMS) for the 3p-DAB based on a novel piecewise time-domain analysis (TDA) and optimization process that obtains the optimal control parameters for minimum rms phase current. Second, this article proposes a novel closed-form minimum current stress optimization (MCSO) DCC scheme based on the …

Adding onboard solar generation to electric vehicles (EVs) is one way to help reduce their charging needs and/or increase their driving range. To maximize the potential benefit, differential power processing (DPP) converters can be implemented to maximize solar energy capture in partial shading conditions. Furthermore, an isolated high step-up converter is required to transfer solar energy to the high-voltage battery, and a buck converter is useful to create an efficient direct path from the solar cells to the low-voltage accessory bus. If implementing these power electronic requirements with separate converters, the component count is high and power density can suffer. Thus, this article proposes the first multiport converter with solar DPP, an isolated high-voltage output port, and a low-voltage port, which is uniquely suited for solar-charged EVs. The switch count is low, and a simple control strategy is proposed to …

The auxiliary power module (APM) is a vital component in electric vehicles (EVs) that enables efficient power transfer from the traction battery to low-voltage electrical loads and the 12 V battery. As the EV industry continues to evolve, APM design is facing increasingly stringent challenges, including the need for higher power ratings, higher voltage ranges, higher reliability, and higher power density, with a continued need for efficient operation. However, there is a lack of literature that comprehensively reviews recent APM topologies based on these evolving requirements. This article fills this research gap by comprehensively reviewing current APM topologies from both academia and industry, including unidirectional and bidirectional topologies, single-stage and two-stage topologies, and multifunctional topologies. Furthermore, this article explores several potential future trends for APM design and development.

Isolated dc/dc converters play a key role in electric vehicle applications, and novel multiwinding resonant converters have recently been proposed for on-board and off-board charging applications. Some of these topologies have two series capacitors at the dc bus with a mid-point connection to the windings. Parameter mismatch due to manufacturing differences will cause voltage unbalance on these capacitors, which can lead to safety and reliability concerns. However, the well-known capacitor balancing strategies proposed for other topologies are not applicable to these new resonant multiwinding topologies. Thus, this article proposes a novel capacitor voltage-balancing method for a resonant multiwinding converter. The method uses a simple table to decide on balancing switching states. Time-domain analysis is performed to quantify the control cycles required, and an adaptive control strategy is proposed …

Electric vehicles with on-board solar generation can offer extended driving range and lower grid charging needs than their standard electric vehicle counterparts. The main power electronic challenge in solar-charged electric vehicles (SEVs) is efficiently boosting the low solar voltage to the much higher traction battery voltage. This paper proposes a novel integrated electric architecture for SEVs which relies on a flying capacitor topology for both battery charging and driving the motor. The onboard solar energy is used to solve the common problem of balancing the flying capacitors, which at the same time helps the solar voltage boost problem since the solar power no longer needs to be boosted to the full battery voltage. Simulation results are presented for a 2.2 kW charging system with 150 V rms input voltage and maximum of 600 W available solar power. The current THD reduces from 1.37% to 0.36% when the …

Industry and researchers are investigating both battery electric vehicles (BEVs) and fuel cell hybrid vehicles (FCHVs) for the future of sustainable passenger vehicle technology. While BEVs have clear efficiency advantages, FCHVs have key benefits in terms of refueling time and energy density. This article first proposes the concept of a fuel cell range extender vehicle (FCREV) that uses whole-day driving prediction (WDDP) control, which uses driver destination inputs to determine whether the planned driving trips that day will exceed the useable battery energy capacity. If so, the fuel cell is turned on at the start of the day. The benefit of WDDP control is that a smaller, lower cost fuel cell can be used to greatly extend the driving range since the fuel cell can charge the battery during both driving and parked periods of the day. Furthermore, this research proposes a fast analytical optimization algorithm for designing a …

Ultrawide voltage regulation is required in dc/dc converters interfacing battery energy storage systems (BESSs) and electric vehicle (EV) batteries in dc fast-charging stations with energy storage. Attaining high efficiency of this converter can be challenging due to the wide variation of input and output voltage yet is important due to the high power transfer. This article proposes a novel control strategy for the semi-dual active bridge (DAB) converter to achieve wide voltage gain while increasing the efficiency at operational points with high input voltage and low output voltage, which is a commonly occurring scenario when the BESS is fully charged, and the EV battery is at low charge. Furthermore, this article also provides an algorithm to determine the required phase shift in real time for any operating point, eliminating the need to devise the control trajectory offline. A 550-V, 10-kW experimental prototype is built and …

Fuel cell hybrid electric vehicles (FCHEVs) have zero harmful emissions, fast refueling times, and long driving ranges. Autonomous FCHEVs add benefits such as collision avoidance and driver convenience yet increase vehicle energy usage due to sensors and computation. Thus, it is important to optimize vehicle speed trajectories and the energy management strategy (EMS) of autonomous FCHEVs to minimize energy use. This article uniquely proposes to achieve this goal using convex optimization, with detailed vehicle loss calculations that can be run in real time. The two novel approaches proposed are: 1) the successive method, which solves the speed problem then the EMS problem, and 2) the integrated method, which uniquely feeds back the fuel cell efficiency to the speed algorithm to solve the problem in an iterative integrated manner. The simulation results show that the integrated method uses 0.19% to …

Recent interest in electric vehicles with onboard solar generation presents a new opportunity for using solar electric vehicles (SEVs) for distributed generation when the traction battery is fully charged. This concept presents a new power electronic challenge: the onboard charger should have high efficiency in the grid-to-vehicle (G2V) direction for normal charging power levels (i.e., 6.6 kW) and also high efficiency in the vehicle-to-grid (V2G) direction for much lower solar power levels (i.e., < 800 W). However, typical onboard charger topologies have low efficiency at light loads. This article proposes a novel bidirectional LLC+C converter to address this challenge. It operates as a full-bridge LLC converter in the G2V direction and a half-bridge LLCC converter with a smaller transformer in the V2G direction. Simulation results show a maximum efficiency gain of 5.1% in the V2G direction compared to the standard full …

Simulating Electric Refuse Collecting Vehicle Performance: Permanent Magnet Versus Switched Reluctance Traction Motor

Authors

2022/6/15

Refuse collecting vehicles (RCVs) that use internal combustion engines (ICEs) have very poor mileage, mainly due to their tendency to idle for long periods and frequent number of stops. This type of drive cycle is better suited for electric RCVs (ERCVs) which consume much less energy during idle periods and are generally more efficient. ERCVs traditionally use traction motors that incorporate rare earth metals in their design. These permanent magnet motors (PMMs) have as draw-backs: high cost of magnet material, sensitivity to demagnetization and increased concern towards properly securing magnets in the rotor. Switched reluctance motors (SRMs) do not use magnets and thus do not suffer from these drawbacks. Their low-cost design and high durability offer an enticing possibility for an ERCV, which typically sees heavy use and requires significant maintenance. The ERCV is also potentially less affected by …

Electric vehicle (EV) on-board chargers (OBCs) should have high efficiency and high power density. Since the transformers in isolated OBCs generally lower both of these metrics, this paper proposes a novel non-isolated OBC with very high efficiency and a low component count. Active filtering is proposed to allow the use of smaller dc-link film capacitors to further improve power density. This paper discusses the design process for the dc-link capacitors and the operation of the active filtering control. Simulation results show that for level 2 charging, the proposed converter has a peak efficiency of 98.8% and efficiency of 98.6% at full 3.3 kW load. Furthermore, the simulation results confirm acceptable THD and power factor performance of the proposed topology.

In electric vehicle fast charging applications, the isolated dc/dc converter charging a battery electric vehicle from a battery energy storage system should provide high efficiency over a wide voltage gain. The semi-Dual Active Bridge (semi-DAB) converter is an excellent choice for this unidirectional application. However, achieving the high efficiency of these converters is challenging when the input and output voltages vary over a wide range. Thus, a novel two-winding semi-DAB converter is proposed in this article to improve the overall efficiency with a variable turns-ratio, which minimizes the converter conversion effort, so that the required effective voltage gain is within a reasonable range even as input and output voltages vary widely. Furthermore, a control law is also proposed to determine the operational structure of the converter, i.e., the turns-ratio and the bridge configuration, which reduces the converter peak …

Photovoltaic (PV) arrays exhibit multiple local maximum power points (MPPs) in their I-V and P-V characteristic curves when different modules are subjected to different radiations at the same time, known as a partial shading condition (PSC). Hence, tracking the global MPP is crucial to increase the PV system efficiency. Conventional global MPP tracking (GMPPT) algorithms suffer from slow convergence, while some can fail to track the global MPP during PSCs. This article proposes a totally new approach to finding the global MPP during PSC using a single current sensor: the parabolic assumption GMPPT algorithm uses a fixed number of current scans (steps) equal to the number of solar modules connected in series to directly and immediately calculate the global MPP. The proposed algorithm uses simple parabolic equations to calculate the global MPP near-exactly during PSCs. The performance of the proposed …

This paper presents an efficiency evaluation of three silicon carbide (SiC) inverter topologies: two-level (2L) voltage source inverter (VSI), 3L neutral-point clamped (NPC), and 3L T-type inverter. Their efficiency is evaluated for powertrains rated at 400 V and 800 V, and using SiC MOSFET devices rated at 650 V and 1200 V operating at a switching frequency of 30 kHz. Firstly, the efficiency is evaluated at different operating load currents, on a per-unit scale. Secondly, the efficiency curves are mapped into torque-speed 2D maps of 120 kW interior permanent magnet (IPM) motors. Thirdly, the resulting efficiency maps are employed in an electric vehicle (EV) model, in order to study the performance of the three inverters on standard drive cycles. At the vehicle level, the energy consumption of the vehicle using the studied inverters is analyzed. It is found that 3L SiC-based inverters are most competitive in the 800 V …
