I am looking at building a HV EV and am looking at SoC meters that go through a shunt (see pic). Most of the ones I find are designed for a maximum of 80 V. My battery have an output of 288 V and I was wondering if a shunt lowered the Voltage so that an SoC of 80 V would work. If they don't work, do you guys know of any HV SoCs?
A shunt is merely a low value resistor that measures current by turning it into a voltage referenced to the reference potential of the HV battery (aka negative terminal).
That PS1 box next to the state of charge meeter will lower the voltage 5:1 or 10:1. The SoC has option in it to specify which voltage divider you're using.

Note: TBS 1:10 Voltage Pre-scaler not available until further notice. The Expert Pro 1:10 Passive voltage prescaler extends the voltage sense input range of the Expert Pro from 0-35VDC to 0-350VDC. Being a passive prescaler, these units are not equipped with an internal DC-DC converter. This...
