Electric Vehicle Technologies spans from 48Vmild hybrids to Energy Independent Vehicles EIV

LONDON, April 24, 2017 /PRNewswire/ -- Electrical machines act as motors and generators in many different propulsion roles, they are increasingly complex taking more of the burgeoning electric vehicle value market -growth on growth. Only here is this big picture based on a host of global visits, interviews and analysis in late 2015 and mostly in 2016.

A deeper analysis on the report: https://www.reportbuyer.com/product/4447338/

Here are some key findings of the study:

·         As vehicles electrify to meet new emissions laws and improve economy and function there are added issues of cost, reliability, life and integration of the now more-complex rotating electrical machines REMs needed.

·         As a motor this can mean driving the wheels or propeller and both starting and boosting a downsized and down speeded fuelled engine where there is one.

·          As a generator it may be making electricity from the rotation of the engine and regenerative braking. It may also be receiving electricity from suspension and other recuperation and from energy storage, stopping, starting, boosting the engine with extra power when needed - a far more punishing regime than the traditional traction motor encounters though there is plenty of market for them as well.

Voltage trends in EVs

·         Vertical integration increases in the supply chain. It makes these systems a larger part of the cost of the vehicle and makes them contribute more to performance, consumer proposition and emission reduction so OEMs and Tier One suppliers are keener to create and own the IP and more is invested in development.

·         Flatter, smaller and/or more-efficient designs and smaller, cooler fuelled engines (or none at all) in the vehicles will reduce the cooling requirements.

·          In a given REM system, mechanical parts become less of the cost and performance and electronics become more.

·         Advances may occur first in large vehicles because they are bought by organizations sensitive to total cost of ownership, performance and emissions.

·         Most electric aircraft and tactical military electric vehicles already have more than one REM and the best-selling pure electric bus has two in-wheel motors.

Electric car forecast

REMs for converting traditional ICE powertrains to 48V mild hybrid. This is meet the onerous 2025 and 2030 emissions regulations that cannot be met by traditional ICE powertrains in C and D cars and larger vehicles but other benefits accrue. At a fraction of the cost, this gives most of the features of a strong hybrid that does not plug in, so potential is large.
