We traded our old 2008 car for a 2019 Toyota Highlander Hybrid. The Toyota engine has no conventional starter or alternator, but it does have a small 12V lead acid battery to run the low-voltage systems. This battery is charged from the HV “drive” battery with a DC-DC converter.
I‘m adding a tow hitch and plan to use a 7-pin connector that can supply 12V to the trailer. Good news is the car’s 12V battery is in the back just a couple of feet from the hitch, but tapping off that battery for any kind of high current uses (like charging a trailer battery) is questionable because the DC-DC converter is not intended to supply large loads. Have any of you used the 12V side of a Toyota hybrid system for towing?
