This paper designs and develops an emergency rescue service for electric vehicles (EVs), which may suffer from the battery depletion during their trips. After building relevant data models on both chargers and EVs, our design defines the interaction among three parties of EV drivers, the rescue server, and rescue vehicles to responsively process the dispatch request and systematically meet the ...

LITHIUM-ION BATTERY MODELING for ELECTRIC VEHICLES and REGENERATIVE CELL TESTING PLATFORM Andishe Moshirvaziri Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2013 Electric Vehicles (EVs) have gained acceptance as low or zero emission means of transportation. This thesis deals with the design of a battery cell testing platform and Lithi...

Flexibility of small loads, in particular from Electric Vehicles (EVs), has recently attracted a lot of interest due to their possibility of participating in the energy market and the new commercial potentials. Different from existing works, the aggregation techniques proposed in this paper produce flexible aggregated loads from EVs taking into account technical market requirements. The produce...

Current legislation in European countries, as well as in other parts of the world, is putting stricter limits on pollutant emissions from road vehicles. This issue, in conjunction with the increase awareness of consumer for the environmental problems, will require the development of new clean propulsion systems in disruption with the current mobility solutions based on internal combustion engin...

The integration of distributed energy resources (DER) into power systems presents substantial challenges to network planners. Assessing accurately the impact that installed DER will have is critical in areas such as: control of the network within statutory and operational limits; quality of supply; losses; and financial objectives. In particular, identifying the optimal placement, capacity and ...

Car-sharing practices are introducing electric vehicles (EVs) into their fleet. However, the literature suggests that at this point shared EV systems are failing to reach satisfactory commercial viability. A potential reason for this is the effect of higher vehicle usage, which is characteristic of car sharing, and the implications on the battery’s state of health (SoH). In this paper, we forec...

Clutches have been used in internal combustion vehicles and concentrated electric vehicles (EVs) to smoothen impulsion while starting and shifting. This paper proposes a permanent magnet bi-stable electromagnetic clutch unit (PMBECU) which is specially introduced into in-wheel EVs to make the rigid connection between hub and wheel more flexible. Firstly, the operation principle of the PMBECU is...

For several years now, electric vehicles (EVs) have been expected to become widely available in the micro-mobility field. However, the insufficiency of such vehicles’ battery-charging and discharging performance has limited their practical use. A hybrid energy storage system, which comprises a capacitor and battery, is a promising solution to this problem; however, to apply model-based designs,...

We study whether taxi companies can simultaneously save petroleum and money by transitioning to electric vehicles. We propose a process to compute the return on investment (ROI) of transitioning a taxi corporation’s fleet to electric vehicles. We use Bayesian data analysis to infer the revenue changes associated with the transition. We do not make any assumptions about the vehicles’ mobility pa...
