Battery depleted sudden stop!

Anyone else wish that when the battery depleted message comes up you would get a warning first? I was hookin' at 32km in GT mode and BAM!! Battery Depleted happened and the resulting jolt the board gave as the motor stopped threw me off. Not pleasant!!

 

I hear you, that's not good at all. They need to detect this critical condition and once the threshold has been hit to begin beeping the remote and shutting down the board by first activating the regenerative braking to safely bring the board to a gradual stop.

 

Totally!!! I literally came flying off at 32km (or just shy of it) because of it!!

 

You should forward your feedback to Evolve, this type of stuff has to be shaken out for safety reasons. I've had similar experiences with riding full force, leaning forward and had bluetooth connectivity issues hit cutting off acceleration 100%. Its a total setup for a face plant on the tarmac. Boards these days should bring the rider safely back to a slow stop if any disconnects or battery exceptions occur.

 

Even though my board did shut off when the battery reached 0%, It didn't throw me off, there was almost no jolt. I was going 32km/h on full throttle. Is it because I am using the AT setup? I haven't tried the street setup, so I can't tell.

Anyway, I totally agree with you guys, some kind of warning would be really useful!

 

That's a great idea Alex, do you have anyone from Evolve on here actively following along?

 

Also with 'improved' suggestions I find its also good to post what you 'really like' about the board, which for me seems like the good things about it will be rather long once I get to stop onto my new board next week.

 

I do the same. Once it hit 30% I switch over to eco mode and go easy on the trigger.

 

Is that when you hit 30% under load or when at rest?

 

So another GT bamboo AT ride today and thought I'd share distance and battery - I managed 6.1 miles, dipping to 8% on fast and still showing 23% on eco and when still. Does that sound about right?

 

hmmm, should get a little more than that i'd say, maybe the battery needs a few full charges to settle in??

 

For a fair test of range you have to ensure the battery pack is fully balanced. To do that you need the pack to sit on the charger for a minimum of 1/2 to 1 day, maybe even more if the battery is way out of balance. Typically what makes them go out of balance is not to give the battery time after the charge to complete to balance, such as pulling the plug and letting the board sit and also just jetting out the door to ride. You'll get less range and less power if your pack isn't balanced. I always leave my boards plugged in overnight so they're balanced and ready to go in the morning. If you do this there's no need to wonder if it does need to be balanced and also have the maximum range and power the pack can provide....

 

Thanks, I'll try that

 

Would this apply if I'm using a fast charger? Thanks

 

YES. No matter how many amps you put into that battery, the battery pack's cells need to be balanced out by the BMS.

 

Thanks!
