Hello!

A novice here looking for some answers. I'm just working out my cooling system.

I'm using Tesla Modules which are liquid-cooled. I'm planning on using ThunderStruck Motors BMS and charging system. I've got an EVnetics Motor Controller for my DC motor that also needs liquid cooling.

EVnetics has some recommendations on their own particular cooling set-up for the controller, but I'm wondering how I can set up a singular cooling system for batteries and controller.

Using one radiator, and a 12V Prius Water pump to cool the 6 modules, as well as the motor controller. Can the Thunderstruck BMS regulate (turn on and off) the water pump or is it/should it be its own temperature-controlled system using a simple thermostat and relay?

Are you planning on charging in cold weather? If so you might want to add a coolant heater and a separate cooling loop for the batteries. Then just have the pump continuously running for your inverter.

I'm in southern California but would like to make the car as all-weather as possible so will probably end up doing both.

I just run the pump constantly. It's dead-silent and very reliable.
