If electric vehicles were lighter, they would also be more energy-efficient. Not surprisingly, this is a problem researchers are working on – using aluminium.
The Norwegian power grid needs relief during periods when ‘everyone’ is using electricity. Research is showing that variable pricing for the fast charging of electric cars may offer a solution.
Driving range is often a deciding factor when consumers choose an electric car. Lithium-ion batteries are reaching their ability to store energy, which has researchers exploring new alternatives — including solid-state batteries.
Lithium from Norwegian electric car batteries isn’t recycled that often. Instead, it ends up as waste when other metals it’s mixed with are recycled. But this may change.
In a few years we’ll be able to charge virtually wherever and whenever we want with only minimal buildout of the power grid, according to electrical engineering professor Magnus Korpås.
Research shows that fitting tyres with very low rolling resistance, combined with the right road surfacing, can provide just as much noise reduction as traditional noise barriers.
Exemption from excise at the time of purchase is the instrument that has the most influence in persuading people to buy plug-in electric vehicles in Norway, the world’s leader in EV sales per capita. Free use of toll roads is also a factor – for every second electric car driver.
If everyone drove electric cars, there wouldn’t be enough power to charge them all when people got home in the afternoon. The solutions could affect your wallet.
Many people are concerned that electric cars produce dangerous magnetic fields. New research shows that this is not the case.

The Privacy Statement is about how this website collects and uses visitor information. The statement contains information that you are entitled to when collecting information from our website, and general information about how we treat personal data.The legal owner of the website is the processing officer for the processing of personal data.

1. Web analytics and cookies (cookies)
As an important part of the effort to create a user-friendly website, we look at the user pattern of those who visit the site. To analyze the information, we use the Google Analytics analysis tool.Google Analytics uses cookies (small text files that the site stores on the user's computer), which registers the users' IP address and provides information about the individual user's online movements. Examples of what the statistics give us answers to are; how many people visit different pages, how long the visit lasts, what websites users come from and what browsers are used. None of the cookies allow us to link information about your use of the site to you as an individual.The information collected by Google Analytics is stored on Google servers in the U.S.. The information received is subject to the Google Privacy Policy.An IP address is defined as a personal information because it can be traced back to a particular hardware and thus to an individual. We use Google Analytics's tracking code to anonymize the IP address before the information is stored and processed by Google. Thus, the stored IP address can not be used to identify the individual user.
2. Search
If the webpage has search function, it stores information about what keywords users use in Google Analytics. The purpose of the storage is to improve our information service. The search usage pattern is stored in aggregate form. Only the keyword is saved and they can not be linked to other information about the users, such as the IP addresses.
3. Share / Tips service
The "Share with others" feature can be used to forward links to the site by email, or to share the content of social networking. Tips for tips are not logged with us, but only used to add the tips to the community. However, we can not guarantee that the online community does not log this information. All such services should therefore be used wisely. If you use the email feature, we only use the provided email addresses to resend the message without any form of storage.
