MEB battery module cooling plate

Description

In DIY EV conversions it is often not feasible to design a sandwich battery box with heat exchange only at the bottom like in the Volkswagen ID.3 and ID.4 and many other OEMs. So individual chill plates per module is often the best way forward. This allows you to stack modules and still cool or heat them.

The downside is that fluid connections and high voltage connections will be in one box. So please ensure it is 100% leak free and regularly pressure test your cooling system. You can also consider using non conductive coolant just to be 100% sure.

This chill plate has been developed specifically for the Volkwagen MEB battery module and has a thickness of 5,75 mm and weights less than 1 kilogram.

The plates have a G1/4″ connection for the incoming and outgoing connection so you can insert a connection type you prefer. For example an angle swivel fitting G 1/4″-8x6mm, nickel-plated brass.

Due to the non-flat nature of the backside of the cooling plate it is recommended to use one plate per module. Furthermore it is needed to add appropriate spacers.

To ensure optimal heat exchange between the chill plate and the battery module a thermal transfer pad (thickness 1 mm) is needed and available as an option.
