The OBC Onboard high-voltage batteries (400-800V) are first and foremost used to supply the electrical motor (power train), This energy source is also used in the vehicle to feed in energy the whole set of embedded electrical or electronic equipment that require a lower voltage.
The use of a Current Transformer in Automotive OBC is mandatory to reduce the high voltage currents to a much lower value.
The main features to take in mind in order to select the right current transformer for your OBC are:
