Abstract [sv]

Elfordon är en viktig del av omställningen till en mer hållbar transportsektor och för att kunna nå de uppsatta klimatmålen, både globalt och nationellt. Biltillverkare arbetar ständigt med att utveckla olika komponenter för att kunna optimera egenskaperna, däribland laddning. Samtidigt sätts standarder och krav upp kring hur en laddning får se ut för att motverka störningar i elnätet orsakade av laddning i form av bland annat övertoner och reaktiv effekt.

Detta arbete syftade till att utföra mätningar vid laddning av olika elfordon samt plug-in hybrider för att studera eventuella övertoner upp till ordning 40, THD och effektfaktor. En mätbox konstruerades för att på ett enkelt och säkert sätt kunna genomföra mätningar på olika typer av bilar. Mätningarna genomfördes vid olika strömnivåer upp till 16A, och var både en- och trefas beroende på typ av bil-

Uppmätta resultat jämfördes sedan med krav på övertoner som finns i standard SS-EN 61000-3-2. Resultaten visade att både Tesla Model 3 och BMW 330e inte uppfyller standarden för laddning medan Volvo V90 och Volvo XC40 uppfyller standardens krav.

Abstract [en]

Electric vehicles are an important part of the transition towards a more sustainable transportation sector and to achieve the set climate goals, both globally and nationally. Car manufacturers are constantly working on developing various components to optimize their features, including charging and everything in between. At the same time, standards and requirements are set regarding the appearance of a charging system to counteract losses in the form of harmonics and reactive power. This work aims to perform measurements during the charging of various electric vehicles and plug-in hybrids to real-time monitor any harmonics up to the 40th order, to study the total harmonic distortion (THD) and power factor. A measurement box was constructed to carry out measurements at different current levels up to 16A, with different electric and hybrid cars, the charging was made both in single-phase and three-phase systems. Measured results were then compared with the harmonic requirements found in the standard SS-EN 61000-3-2. The results showed that both the Tesla Model 3 and BMW 330e do not meet the standard for charging, while the Volvo V90 and Volvo XC40 comply with the standard's requirements.
