I understand how a thermal management system adds to costs, and decreases range and it seems that these disadvantages have caused Leafs to not come with this system at the detriment of the very expensive battery. More pronounced in the very hot climates.
I propose that you incorporate liquid cooling lines throughout the battery pack connected to a 2 stage coaxial quick disconnect somewhere on the car where an external stationary cooling chiller pack can connect. All cars sit far more than they move, and having this system available when the car is idle could drop the average temperature of the battery, prolonging it's life. It will also remove the heat produced in quick charging so that more quick charges can be done in a trip. Right now with too many, the battery over temps.
Make that coolant connector so that when pulled out halfway, it opens one side to the atmosphere, while the chiller sucks all of its fluid out of the other line, then allows the connector to be taken off without fluid dripping everywhere, and not leaving any coolant in the cars lines to leak or require any maintenence. This way only those who need battery cooling have to pay for it, and nobody needs to have to carry the extra weight around or draw the power from the battery for the cooling system.
