Mini will preview electric car with 2017 Frankfurt auto show concept
Mini electric vehicle auto show
BMW Group’s Mini brand was an early pioneer of mainstream electric cars. Some readers will recall the brand leased the Hardtop-based
Mini E electric car on a trial basis late last decade to help gather feedback from users.
After electric cars, what more will it take for batteries to change the face of energy?
About three-quarters of the way along one of the snaking production lines in Nissan’s Sunderland plant, a worker bolts fuel tanks into the chassis of countless Qashqais—the “urban crossover” SUVs which are the bulk of the factory’s output. But every so often

Grid Interconnection and Performance Testing Procedures for Vehicle-To-Grid (V2G) Power Electronics
William Kramer, Sudipta Chakraborty, Benjamin Kroposki, Andy Hoke, Greg Martin, and Tony Markel
Bidirectional power electronics can add vehicle-to-grid
(V2G) capability in a plug-in vehicle, which then allows the
vehicle to operate as a distributed resource (DR). The
uniqueness of the battery-based V2G power electronics
requires a test procedure that will not only maintain IEEE
interconnection standards, but can also evaluate the
electrical performance of the vehicle working as a DR. The
objective of this paper is to discuss a recently published
NREL technical report that provides interim test procedures...
Sliding mode controller for internal combustion engine for energy-efficient operation of hybrid electric vehicles
Vivek Venkobarao, Chellamuthu Chinnagouder
Int. J. of Electric and Hybrid Vehicles
2010 Vol.2, No.4 pp 282-297
This paper presents a new concept with different control strategies. The developed intelligent speed controller utilises a gear box which includes a gear train with two inputs, one coupled with the engine shaft and another with the shaft of a variable speed controlled motor. The net output speed is a combination of the two input speeds and is governed by the transmission ratio of the planetary gear train. This new approach eliminates the use of a torque converter, which reduces the power loss that occurs in the box during fluid coupling. By gradually varying the speed of the induction motor a stepless transmission is achieved. The developed controller also scores in climbing a step gradient and reversing the vehicle, by intelligent mixing of the induction motor and engine speeds. This approach eliminates the traditional braking system in the entire vehicle design. The use of two power sources, IC engine and battery-driven induction motor, utilises the modern idea of hybrid vehicles. The new speed controller is capable of driving a vehicle even in an extreme case of IC engine failure, during gas depletion and for plausibility errors.

Driving electric? A Financial analysis of electric vehicle policies in France
In recent years, electric vehicles have come to the forefront of public transport
policies. They are seen as remedy for various pressing public concerns and are
thus increasingly benefiting from supportive policy measures. Such measures
remain contested: their impact on actual vehicle uptake rates, their
sustainability, usefulness and justification are far from being self-evident...
