Battery switch to grid

Hi, I have a rather simple model with a battery, an dynamical load and a source representing the grid. Now I want the battery to shut off at 20%. I am using two ideal switches for it but I just cannot seem to get it to work. The battery is discharging but it does not stop at 20%.

Hi @Reinier

I think your connection of the gate is wrong. You are providing additional path between the battery and voltage controller ( i guess). You suppose to connect the gate within the positive line of battery and voltage controller. Besides, I would prefer mosfet to as the switch for the battery (suggestion). Hope you can try it, thanks and good luck.

Ah yes, you are right! I made it work without mosfet. Thank you for your help!
