Electric Scooter LCD on dashboard, powered by a TI Stellaris Launchpad

[arre 0]

Hi all,

 

Another project to the list: 

 

I fitted my electric scooter with an LCD on my dashboard, to display power consumption and the voltages of the batteries, using the stellaris launchpad.

The launchpad provided the digital out pins for the LCD (thanks to The_YonGrand for the lib), and the ADC measurements for the voltages & current of the battery.

 

You can it out in detail on my blog: http://arre234.blogspot.be/ , or directly take a peak in the code on https://github.com/arre525/escooterlcd

 

But here are already a few pictures to get you interested:)

@@arre Looks awsome! Thanks for sharing. What kind of batteries does your scooter use? and pic of the scooter!

Very cool. Need to waterproof the LCD ?

Kudos to the scoot mod!

Thanks guys.

 

@@bluehash, the scooter uses a pack of 4 12V lead gel batteries (sort of lead-acid batteries, but without a liquid electrolyte).

It's a "Qwic Emoto 87" and it looks like this: 

 

 

@PTB: Yeah, the last picture on the forum here only shows the LCD on the dashboard without any protection. I later used a gluegun tofurther waterproof the LCD on the sides, and then put some black tape over the LCD sides to make it blend in more with the dashboard. (But I still have to test the waterproofing to be honest:)

I actually don't have pictures of the finished LCD yet (?), but you can check out a low-res movie on the blog above:)

Looks sweet!

What's the top speed and reasonable range on that scoot?

@spirilis: It's limited to 50 km/h (+- 30 mph I guess). The batteries are unfortunately the achilles heel of electric vehicles. They're expensive, and have relatively low energy/weight ratio. In my case, a 600 euro battery pack gets me 40 km until you really need to recharge, for 2 years until the pack wears out. But since I live quite close to work, it's still a lot cheaper than a car, faster than a bike, and not as loud/smelly as a petrol scooter:) More importantly, it's electric! Which means I can measure the power it produces!

Very cool, good to know. Batteries are the achilles heel in a lot of things I've come to realize

I like the entire thread about the electric scooter and the battry monitoring system. Hope we get to see more Stellaris in electric transports!

A little off-topic, but I had a test ride on a Zero S electric motorbike last week. Really nice to ride and a reasonable amount of power. Way too expensive though.

Cool, I love the way you explained it. Electric scooters are such a fun and joyful ride I recently opt out for VOKUL S2 Tricks Pro Stunt Scooter. best freestyle pro entry level scooter, ideal for age groups between  7-14 years boys and girls with little or no scooter experience. Moreover Vokul model stunt scooters super stylist and gives uber cool looks, comes with easy installation all you need to do is tighten the 3-bolts clamp to put it together. This is the best electric scooter , with High rebounding PU wheels and accommodate the Maximum weight capacity of 140 lbs
