    Undergrad Calculating pre-charge of capacitors on electric vehicle

    Hello! Thank you for your fast reply! I think there is a small mistake in your equation at the end, because R=-t/(C*ln0.1) or am I wrong? R=-t/(C*ln0.1)=5/(0.00188*ln0.1)=1155 Ω The graph is also now correct: http://mustcalculate.com/electronic...?vfrom=0&vto=288&vs=320&c=1880u&r=1155&time=5...
