 Different generations of batteries, improving capacity and
better for environment
 Lead-acid batteries
 Ni-Cad (Nickel-Cadmium)
 NiMH (Nickel-Metal-Hydride)
 Li-Ion (Lithium-Ion)
 Li-Poly (Lithium-Polymer)
 Samsung Galaxy S3 - Li-Ion 2100 mAh battery
 iPhone 5S - Built-in rechargeable lithium-ion battery
 iPad - Built-in 25-watt-hour rechargeable Li-Poly battery
Batteries have been improving
A lot still needs to be done!
Lots of advancements in the battery technology
Solar cell under the screen
Future generation Li-Ion
battery, 2000x more powerful
 The more the number of pixels, the more the need for
computation
 iPhone 5S (1136x640), Galaxy Note 3 (1080 x 1920 pixels)
 True colour (24 bits) requires 3 times the computation that of
256 (8 bits) colours
 Galaxy Note 3 (16M colours)
 The bigger the screen size, the more power it needs
 Galaxy Note 3 (5.7”), iPhone 5S (4”)
 More processors, need more power
 Dual core (2 processors), Quad core (4 processors)
 More radios suck more power
 Wi-Fi, 3G, 4G, Bluetooth, NFC, etc.
We need bigger and better batteries
Car comes with no battery. User gets a contract with the battery
provider. Renault reserves the right to prevent the battery from
charging at the end of the rental period or if you fall behind on
paying the rent for the battery.
Intelligent Battery: Renault ‘Zoe’
A battery that can communicate with other
batteries and make decisions based on these
communications and a pre-defined set of rules
What is a ‘smart’ battery?
The connected individual
Headphones
connected to
phone or tablet
Phone
Tablet
Other connected
device like Laptop
Headphone needs power - 1
I am low on
power, who can I
borrow it from?

I can lend
some
Take as much
as you need
Headphone needs power - 2
I am low on
power, who can I
borrow it from?
I am 50% full
but have a higher

Wireless (Inductive) charging
Limited time and power availability
Devices decide among themselves who should charge when, how
much, etc.
Charging devices
I will charge
first as I have
highest priority
I don’t need
much power but
I can wait
I will go next
Let me know
when you are all
done
 Early morning: X goes for a jog with smartphone and headset.
The smartphone has GPS tracker and fitness app – highest
priority
 Late morning: X goes to work listening podcasts on the
smartphone
 At work: X needs to work on laptop, should always be at least
50% charged
 In evening: X is coming back from work, speaking on phone to
his friends and family. Phone and Bluetooth headset needs to
be charged
 Late evening: X is watching TV/Video on his tablet.
Context is important too
Charging priority based on context

Priority Rules
Lowest priority Highest priority
Borrowing power from friends / colleagues
Please lend me
some power,
phone about to
die
Sure, will lend
you power to
make this one
call
 Facility to charge devices in public places is a boon for end user
and good advertisement for companies and airports, etc.
 Wired charging stations are being replaced by wireless ones
Competing for power at public spots
 ‘Smart charging’ can give higher priority to subscribers, devices
of certain brands, devices with lowest charge remaining
Competing for power at public spots – Next Gen
 Our interest is working in these future
technologies in partnerships.
 We generate ideas and help our
partners translate these ideas into
reality.
