Solar Powered Scotter

Hello, I'm new to Arduino and to the community.

I was thinking of making a light weight, solar powered electric scotter.

I was considering on using the following components:

solar panels
Arduino nano
Relay module (a.k.a. buck converter)
9V Batteries (rechargeable)
LCD Display
Pointiometer
Motor Driverboard
36 V motor

I would like to make the scotter to reach the speed of 23 miles per hour and have an "electrical shift" (by that I mean to program the Arduino to go in one stage or "shift" 10 miles per hour and another stage or "shift" to go 23 miles per hour by a flick of a switch.

Is it possible to make a charging station on the scotter? I'm thinking of making the batteries being charged on the same scotter, when the batteries are full, the current would go directly to the motor and the components. I've considered using a "buck converter" (relay module) for this specific task.

I'm unaware if its possible to run an electric scotter by using a few 9V rechargeable batteries and using a voltage booster to be able to have enough current without having to use a lot.

I'll bet you mean "scooter".

Do the experiment to find out. No one has any idea what motor you have in mind.

It does seem unlikely that the 9V batteries intended for smoke alarms could move a human around at 23 mph.

Is this a scooter for a mouse?

Solar scooter? I think electric bikes are the best options that you must consider. You can also see the specification of tesla electric scooter in this regard.

Alas you won't be able to gather enough energy to be useful by adding a solar panel to a scooter, unless you only drive it 5 minutes per sunny day!

You can have a nice big stationary solar panel to recharge the batteries, perhaps 60W or more panel, and maybe swap out battery packs.

Budget at least 250W motor power, perhaps more like 500W for that top speed.

9V batteries????? No, don't even think it, utterly infeasible.

You need LiPo, LiFePO4, or some other lithium power pack of substantial capacity, plus the BMS and charger to go with it. SLA or NiMH are also possible, but less satisfactory in terms of power density. Think 36V 10A,
peaking at 20A drain, so 10Ah capacity might give upto an hour's use.

Relay module (a.k.a. buck converter)

A relay is not a buck converter, nothing like.

I didn't knew Tesla had their own scooter, I'll check it out.

I can make those changes.

Ok, thanks for that.

Can a BMS be connected with 2 packs of Lipo batteries (as in 2 Lipo battery packs connected to 1 BMS) or does each pack must need its own BMS?

A relay is not a buck converter, nothing like.

My reference was to boost the voltage from a small battery pack, but my primary idea (for the batteries) is left to dust. Thanks

I forgot to mention about the 9v battery. The reason why I mentioned that its because I've heard that it could be done with it using a voltage booster. Now it really sounds like a safety hazard, thanks for the warning from everyone here.
