Elbilsladdare och batterier: Utmaningar och nyttor för elnätsbolag

Abstract [en]

Electric vehicle chargers and batteries installed on the electrical grid have increased in

the recent years. EV-chargers can increase the power needed in the grid while

batteries give costumers new possibilities to control their own power consumption.

This opens up a new situation where synergy between the utility and the costumers

can be achieved. Less maximum power drawn from the grid allows the utility to use

the power elsewhere while the costumers pay less for their electrical bill.

This master thesis proves that the potential for synergy is good from a technical

perspective, both with current electric vehicle charger technology and with future

technology that will allow power also can to be fed into the grid and not just drawn

from the grid.

Although the technical potential is good the practical potential is still limited due to a

number of reasons. Currently, the economic incentive for the costumers is too small

to justify an investment in batteries so the cost for batteries needs to decrease.

Furthermore, the legislative situation is far from optimal with a legal framework that

does not encourage batteries in any part of the electrical grid. The legal and technical

challenges create a situation that causes further problems with possible business

models and all of these problems need solutions in order to stimulate the market for

batteries on the electrical grid.
