Scooters thats can use different batteries

[scootergrisen]

What scooters are out there that can use multiple types of batteries?

Currently it seems like there are different voltages, different chemistry, different sizes, different connectors, etc. so that it almost seems like you cant use a battery from another scooter unless its the same model etc.

Are there anything for making it possible to use something like a 60 volt battery in a scooter with 48 volt system?
Or maybe the controller could just detect the voltage and use both 48 and 60 volt etc. without modifycation.

It would suck if you have 10 batteries and you get a new scooter but you cant use the batteries in the new scooter.

I saw this drawing where the scooter can have two sizes of battery and also mixed (1 big 1 small).

Problem is the spec of the electronics. 36&48V will likely be interchangeable with a reprogramming of the controller. Same for 60&72V.

Go from 48V to 60V system and caps and mosfets will blow as there’s a spec step between these.

84V and upwards, difficult to say without checking each controller and dc-dc but these aren’t so common for the scooters.

Lets say you designed a scooter with the intent to support different batteries.
So the scooter might have electronic components that support all kind of voltages and connectors etc.
Or if that is not possible then have extra electronics and the scooter can switch between them.
Like maybe have 3 controllers, one for 36 and 48 volts and one for 60 volts and one for 96 volts.

Maybe you insert a 36 volt battery and the controller could automatically reprogram itself according to the voltage or switch to the correct controller.
Maybe the BMS inside the battery can communicate with the scooter and tell what kind of battery it is.

What about the motor can you get motors that can run on anything between 36 to 96 volts?
Guess it could be a little hard to have 3 motors to switch between like the controllers.
Else i guess have the motor at 96 volt and then if you insert a battery that is 60 volts there can be like a dc to dc converter to bring it up to 90 volt.
