Here is a Prius one, the relay is rated at 400v and appears to have a current sensor on it.

That was my thoughts on it. I already have a Prius one at home to play with and a ~144v Honda Hybrid battery pack with a pre-charge/contactor setup on it that I'm going to use for higher voltage testing and test out using the Yaris inverter for charging.
