Testmetodik för vintertestning av el- och hybridfordon

Sammanfattning

With gas prices persistently rising, electric and hybrid vehicles are

getting more and more common and in recent years several new electric cars

have evolved on the market. Although the energy consumption and low

emissions are a huge benefit of the electric cars, they inevitably suffer

from high prices, short range and time consuming recharging periods. To be

able to withstand the competition it is important that electric vehicles not

only can withstand general were and tare, but also the harsh conditions that

ordinary cars is exposed to in daily usage. The purpose of this project is

to develop a test

methodology which replicate situations that could appear in daily usage of

electric or hybrid cars and to understand the problems related to usage of

electric cars in winter conditions. This paper also discusses the major

differences between hybrid cars and electric cars. Cold climate testing has

been carried out and energy consumption, safety, functionality and

performance are analyzed.

Ultimately, this study has resulted in test code, which could be viewed upon

as a guide for testing electric vehicles and hybrid vehicles in winter

condition.
