Projektplannering för laddstation samt elkvalitéstudie

This degree project is done in collaboration with Vinnergi AB at their officein Halmstad. The aim for this project is to deliver a proposal for a new charging station in Trelleborg with focus on technology implementation. With an increase in electrification in the transport sector comes the need to construct more charging stations in order to keep up with the increased demand for charging points for electric vehicles. This report will cover research for existing chargers at the same location in order to determine the current usage of those chargers, the amount of chargers that the nearby electrical grid can handle as well as a power quality study for the existing electrical grid. To reach the specified goals, simulations of the actual electrical grid were conducted along with several calculations and technology considerations that were partly based on the simulations. This research came up with a new proposal for a charging station with two charging posts for fast charging with a charging capability of between 175 kW and 350 kW. Cables, breakers and a grounding system for the chargerswere evaluated and chosen along with a fundamental budget for the whole project. This proposed charging station will extend the charging capabilities in the area and be a part of keeping up with the increased demand for fast andreliable charging in Trelleborg
