Default Re: Ather Energy unveils the S340 Electric Scooter

I am a Hero Electric scooter user for past 4+ yrs. Please see my review post 3 months of using it here (Hero Electric @ Auto-Expo 2012)

So far, I have changed the battery pack once (cost ~11k). It lasted close to 2.5 yrs. I think my current pack might last for another 6 months max. These days, after a full charge I get approx 20-25km range. In six months the range will most probably come down to 5-10kms, and then I will have to go for a new battery set.

Will this new bike change this reality? Will this new patented technology around battery (thermal & packaging) improve the life and efficiency of battery? Hero had mentioned that the bike will give 60km range. In the first few months, I did get 50-55kms range. But with in 4-5 months, the range dropped to 30+kms and that's what one can expect in the long run. Since this new bike can run much much faster than my Hero bike, it will use lot more energy, so hope this will be using a much bigger battery pack, which will in turn increase the battery cost considerably.

This new bike looks really cool. But from a user perceptive, I would need the following, before considering buying a new electric bike.

1. Long lasting battery (at least 5 years) with acceptable degradation of efficiency drop. For example, a 10% drop every year in the Kms range promised is bearable. Otherwise it does not make any economic sense.

2. Gear system. With out it, it is really a Cycle with a motor.

Please note that my views are from my experience with Hero electric bike. I am NOT in any way saying or implying that this new bike don't address any of these issues. If the above mentioned 2 points are addressed in this new bike, then it will surely become a gem in the electric scooters scene.

Ahem, I am unable to see anything new. Even the photograph is from the launch in Feb. Wish they had something new to say after 4 months of silence.

Smile Re: Ather Energy unveils the S340 Electric Scooter

I was invited to their pre-order customer preview on the 18th of june.

Had a chance to interact with a lot of their engineers, CPO and CBO.

I forgot to take any pictures , but I'll list out some of the things that stood out from my point of view.

The embedded systems part.
  • They are heavily focusing on telemetry and data logging to make the experience better.
  • If you are navigating from A to B and the range calculated isnt enough, the system will automatically add a waypoint to the closest charging center.
  • They also track the riding habits of users. They showed us an interesting overlay of graphics representing acceleration/ lean angles on a track. This should be accessible to the end user.
  • They are planning to have one accelerometer and one inertial sensor on the final version. Their test setups are running 3 accelerometers.
  • they also plan to add always on condition monitoring of the vehicle by measuring motor current,vibration levels,temperature of the battery etc. This in theory should lead to preventive maintenance with proper analytics.
  • You will have to pay for data eventually.
  • It has accident detection based on the accelerometer, they are planning to add automatic calling of an emergency number to the final release.
  • They are going to map road quality (potholes etc) into their navigation, with accelerometers + GPS data.
  • I asked them about the privacy/legal implications of all this data, they haven't really thought that part through yet. They have an incognito mode for the GPS.
  • The system optimises constantly to get you to your destination, will reduce top speed/acceleration to ensure you have enough range. Calculates based on your navigation data.

Will continue with the interesting mechanical design bits in the next post.

Instead of LCD screen, why don't they just incorporate a way for a user to embed his/her cellphone in that slot - that can take care of the navigation and the speedometer, etc. All they'd need to build is an app.

Oh that would warrant water resistance first and maybe even dent battery life of mobile.

Detailed Specs revealed.

Quote:
Ather S340 will have a driving range of 60 kms. Recharge upto 90 percent could be accomplished in an hour while the lithium ion battery pack will offer lifecycle of 50,000 kms or lifespan of 5-6 years. It can do a 0-60 kmph spring in 12.11s. Max torque output stands at 14 Nm.

That peak torque of 14NM is quite a bit higher than the typical 100-125cc bikes and scooters. The 0-60 top speed of ~12 seconds is slower than most of the entry bikes and scooters (which are in the 9-10 sec range), but considering the higher torque and the fact that peak torque will be available from start, expect it to be zippier than the typical scooter in acceleration from standstill and in start stop traffic.

EDIT: This link has a video of a test run

Nice to see it having a BLDC (Brushless DC Motor). Reminds of reading Hall effect in school! Lets see more we have in store!

Default Re: Ather Energy unveils the S340 Electric Scooter

I am keen to start manufacturing electric motorcycles in the country and have been itching for a startup for the last 2 years myself. But after conducting a bit of research on the evolution of the battery technology, I decided its best to give it another 5 years at the very minimum until there is a vast improvement in price to performance ratio for EV's to be commercially viable in the Indian market.

At this moment there isn't much of a benefit if you to switch to EVs but with the uncertainty of gas prices in the next 5 years, you could see a lot of people jumping over and by then I hope there is some improvement over battery performance.

Ather and Tork motorcycles have a considerable advantage now by starting first.

Ather energy gets big funding from Hero Motocorp. Things should get more interesting now.

Can you take out the battery and charge it standalone?

That could be a very nifty feature for people like me living in apartments. It would be difficult to setup a charging point at the parking place (and more difficult to ensure it is not vandalized or misused). But if you could take out the battery and charge it in your home then it would make life easier. I would consider buying this scooter if this kind of setup is available. Would be perfect vehicle to commute to my tennis court (~2km) and office (~1km from next month). Just recharge the battery every weekend, would be very convinient!

I had asked exactly the same question and someone had replied as to the weight of the battery being 30-40kgs - not something you can easily carry home.

Thanks. 30-40Kg is really too much of weight and that would preclude taking it out and recharging standalone. Ah, why the batteries have to be so heavy. The last frontier in mass adoption of electric vehicles really. There is still one of two generation of advances in battery technology needed before EVs truly become mainstream.
