Charging the 450
There are 3 ways to charge the vehicle-A home charging point, A cable charger and the public Ather Grid charging points. Unlike other EVs they just don’t give a charging cable and be done with it. Ather’s team will come home, survey the location beforehand, finally install a home charging point at your home. The charging point is similar to the pod that we see in the Ather grid public charging sans the 5A/15A plug. The Pod looks like an alien from some Sci-fi movie to me !
The Home charging Point
An installation involving upto 20 mtrs of cable/conduit is not charged (they call this as a standard installation). Above 20 mtrs, they charge for the cable and conduits only. My parking slot was around 42mtrs. So I was given an estimate of 2900+ rupees for the extra 22 mtrs. I had paid it online. The actual installation was done 2 days before the vehicle delivery and the final cost was 2400+ rupees. The difference was refunded later. Talking about installation, it seems around 20-25% of the installations are above 20mtrs. Also they say around 7% of the apartments have apprehensions on fixing this. My apartment already had many other EVs and also wiring trays to route wires which made things easy for me. I’ve seen some new apartments already providing a power socket at each parking slot.
The home pod is paired to the scooter and automatically authenticates my scooter every time I charge it. Forget any other EV, we can’t charge even other Athers. So there is no worry of power theft when you’re not around it. It also has inbuilt surge protector. Home Charging Point comes with a 3 year warranty that covers manufacturing defects excluding cable, connector, and physical wear & tear. The home charging point is IP54 rated; so it can be safely put outdoors as per Ather. If there is any problem, the light blinks red. It weighs around 5kilos.

The actual plug that we have to plug into the scooter is similar to a Euro Type II plug but a little different in the number of pins. The socket on the scooter is on the left side of the luggage hook and is covered with a flap. As soon as we plug it in and switch on, a solenoid locks the plug in place with a feeble “click” sound. It can’t be removed while charging.

The pod has a blinking green light while charging. After sometime, a fan switches on behind the front body to cool the on board charger. There is also a open slot just beside the front wheel in the wheel well cladding to aid air circulation. It can get noisy and disturbing in small houses when the scooter is parked close to a window. My pod is in a basement parking far away from homes and hence doesn’t disturb anyone. We can keep it plugged in even after charging is complete as it automatically cuts off power. From 30% to 100% I’ve observed that it takes around 2 hours for full charge.

At anytime while charging, tapping on the screen will show the current status of charging.To stop charging, just put in the key and turn on the scooter. It displays a message to remove the plug to start riding or remove the key to continue charging. At this time the solenoid also unlocks the plug with the same “click” sound and we can remove the plug and hang it back to the pod.

The portable charging cable
I have also purchased the optional charging cable which I intend to use for emergency situations, charging at places where there are no Ather grid points or to go a little far away from city limits. I recently did a 120Kms two-day trip and I used this cable to charge it overnight for my return on the second day. This is similar to a laptop charger using a 5A plug and an adaptor with an LED. The LED glows green for charging and red when not charging.

People who live in rented homes or places where installation is not permitted, can opt for this instead of the Alien pod. While the Alien pod is paired to the scooter it came with, the cable is universal. One cable can be used for any number of Athers. One thing to note is the cable charger is not waterproof and neither does it cut off power automatically. People who have only this must be aware of this and switch off once the charging is complete
A person having a designated parking space, and easy access to the Ather Grid and maybe travel around 50-60 km a day can easily go for the home charging pod. But for someone who hasn’t got a fixed parking space (like a rented house), who happens to travel on a route that’s beyond Ather Grid locations or has unpredictable travel patterns, the cable suits better.
Ather Grid public charging Point
Apart from the Ather grid at the Ather experience centre where I was unsuccessful in charging our E2O plus, I’ve not experienced the Ather Grid point so far. However I’ve see it in a couple of places. Ather’s marketing materials say that in Bangalore we are never more than 4kms away from a parking slot. True to that, the closest Ather grid point is 4kms away from my home. The points are mostly installed in Cafe’s, Restaurants or shopping areas. In a way it is good because while the vehicle is being charged, there is something that we can do to pass time instead of just waiting. This makes the wait seem shorter. This is free till December 2019 for all Electric vehicles. After that it’ll be based on the subscription plans.
The charge status is also shown on the mobile application with a nice graphic image. This graphic is same irrespective of if the vehicle is being charged by the home point, public grid or the cable charger
That green glow keeps moving along the wire…nice graphic
After couple of minutes of plugging in, the time taken for charging is displayed. I don’t know if it is programmed like this, but this information is available at the exact time the cooling fan starts! When the charge status is below 50% it shown the time to charge till the charge is 1.5 times the current percentage and till 80%. if it is above 50% when it is plugged in, then it displays time till 80% and time till full charge

Time to charge up
It takes almost the same time to charge as displayed. most of the times it completes charging a minute or two earlier than what is displayed. When the charging is done, it displays the same . However I’d have preferred a notification on the phone when the charging is completed.
Charging done
The above two pictures are taken when the vehicle was being charged using a cable. It was charging beside the E2O. We have a 15A and 5A power socket made when the E20 charging point was installed. It was useful now with both the scooter and the car charging together.

Before you ask me, The E2O plus’ plug and the Ather plug are completely different!
From the above screenshots of the charging progress, I can calculate that it charges at around 2 minutes per 1% of charge till 80% and at around 4 minutes per 1% of charge from 80%-100%.
Home charging takes the same time. Brochure mentions the same too (2hrs40mins for 0-80% and 4hrs 18mins for 0-100%)
Ather grid public charging points are DC fast chargers and they charge the scooter at a rate of 1Km/min That’s Roughly 45 seconds per 1% of charge (for 0-80%). However the manual says too much of fast charging is not good for the scooter.
When the scooter is kept overnight without charging, there is a drain of 2% in the battery. This is called Trickle drain or vampire draining. whenever the scooter is not being used for more than 3 days, it is recommended to shut down the scooter to reduce this trickle. Ather recommends that the scooter be charged at least once in 100 days to avoid creating any damage to the system.
Theoretically the scooter consumes 2.4 units to charge from 0 to 100 (1 cycle). For ease of calculation let’s take 3 units. a 100% charge give me an approximate 70kms. At 6.5Rs per unit (max in Bangalore) that’s 0.25 Rs per km. Considering trickle draining, it would still be around 0.30 Rs per km. Which is very cheap compared to around 2Rs per Kms any other scooter.
This above calculation is a very pessimistic one. If I calculate exactly with the figures I’m getting… 2.4 units for full charge, considering trickle charge it will be 2.5 units, I get 85Kms. So it would be less than 20paise per km.
Talking of costs, Ather reimburses the electricity consumption of the scooter for consumers with AtherOne subscription. This is done every quarter at the rate of 6.5 rupees per unit. This is the price per unit for domestic users of BESCOM for the 101-200kWh slab. I don’t think this payout will change if you have a commercial connection (say some shop)
