Comment on Altech’s sodium chloride solid state battery exceeds expectations

If you meant for a single car, that might be a bit lofty, but for options available it makes sense (ie different trim packages for single model sort of thing).

I see it breaking down as follows: Grocery-getter for an old couple won’t need much capacity. Just enough to get around town over the course of a day of needed and can plug in and fully charge overnight from a wall outlet. The other would be a battery capable of larger distances but needs a little bigger outlet to charge between stops of a long trip.

What difficulty do you see with this concept in a single car? This technically exists already as there are multiple charge controllers and BMS systems in EVs shipping today, they are just managing different modules of identical chemistries in the single car.

  Not so much difficulty but practicality. I would see it being similar to having 2 gas tanks in a car where one is for a high octane fuel and the other for a low performance fuel like ethanol.

    And these exist completely separate to EVs. They’re called bi-fuel vehichles.
    
    “How Do Bi-fuel Propane Vehicles Work? Bi-fuel propane vehicles typically use a spark-ignited internal combustion engine. A bi-fuel propane vehicle can use either gasoline or propane in the same internal combustion engine. Both fuels are stored on board and the driver can switch between the fuels. The vehicle is equipped with fuel tanks, fuel injection systems, and fuel lines for both fuels” source
    
    They aren’t common in the USA because of they way emissions laws were written which made it uneconomical in many cases for auto makers.
    
    There isn’t the same challenge in EVs, especially where we’re talking the “fuel” is just electricity which is common to both chemistry batteries. I see no challenge for EVs.

    I was entirely unaware of this type of vehicle so my initial comment was made without considering them. If there is a market case for such a vehicle, then they would likely fall into that same category.

    This has me insanely curious as to where these are common and what are their emissions laws. Time for a trip down a rabbit hole.
