Introduction- Battery operated ZEV (BOZEV)
What is BOZEV?
•
Battery Operated Zero Emission Vehicle (BOZEV) or All-electric vehicle derives all its power from
its battery packs, and thus has no internal combustion engine, fuel cell, or fuel tank. BOZEVs
include bicycles, scooters, skateboards, rail cars, watercraft, forklifts, buses, trucks and cars.
•
It can be referred to as the next generation vehicle that does not result in any harmful emission
during vehicle operation.
BOZEV v/s Fuel Propelled Vehicle
1) No Emissions: Electric cars are 100 percent ecofriendly as they run on electrically powered engines.
2) Cost Effective: In long run, owing to much lower
operating cost, BOZEV is quite cost effective
compared to HEV or fuel based vehicles
3) Low Maintenance: Electric cars run on electrically
powered engines, and therefore there is no need to
lubricate the engines.

4)
Reduced Noise Pollution: Electric cars put curb on noise pollution as they are much quieter.
5)
Safe to Drive: Electric cars undergo same fitness and testing procedures test as other fuel
powered cars.
6) No Gas Required: Electric cars are entirely charged by electricity you provide, meaning that one
doesn’t need to buy any gas ever again.
7) Savings: These cars can be fuelled for very cheap prices, and many new cars will offer great
incentives to get money back from Government for going green.
Applications of BOZEV
•
Electric truck - Fire truck, Trash truck, Garbage truck etc.
•
Cleaning vehicle- Floor cleaning, Door/wall cleaning etc.
•
Electric Cars- Small size, Self-powered etc.
•
Two/Three Wheeler Vehicle- Motorcycle, food catering, electric bicycle etc.

Renault-Nissan – Market Leader in BOZEV
• Renault-Nissan has developed and patented many technologies pertaining to BOZEV aimed at
manufacturing zero emission vehicles. Renault-Nissan was the worldwide market leader in 2014 in terms of
sales of electric vehicles.
• In 2014, in terms of percentage, Renault-Nissan sold 26% of the total electric vehicles, sold worldwide,
which was more than twice the numebr of electric vehicles sold by Mitsubishi.
•
Top electric vehicle models from Renault-Nissan included Nissan Leaf, Renault Zoe, Renault Kangoo ZE,
and Renault Twizy.
•
Nissan Leaf sold 50 units in 2010, 22144 units in 2011, 26973 units in 2012, 47716 units in 2013, 61507
units in 2014, showing significant rise in number of electric vehicles sold annually.
•
Nissan Leaf is available in 46 countries. Presently, a Nissan Leaf fully charged 24 kWh battery lasts 135
km. By 2016, a Nissan Leaf fully charged 30 kWh (planned) battery is expected to last 172 km and the
normal life of the battery pack is expected to be 10 years.

To serve the purpose of an Exemplary Landscape Study, detailed analysis for over
500 patents/published application was done, and ~260 documents were selected as
being relevant to the instant study. The selected documents were carefully analyzed
and categorized into one or more categories.
•
Further, trends were observed to derive key insights from the analyzed set of
patents.
•
Details pertaining to analysis of patents/published applications can be accessed

Latest Technologies
Shortcomings of Current Technologies:
The automotive industry is changing rapidly, much more quickly than at any point in the last 20 years.
There’s a major shift towards green technologies and increased fuel economy, driven by both regulations
and consumer demand.
In the next 5 to 10 years, every car on sale will offer a hybrid, plug-in hybrid, or full EV variant, and the
adoption rate of these technologies will increase dramatically.
Manufacturing is always a challenge, and as the EV industry scales up, there is going to be a lot of room for
people who can figure out how to reduce the cost of manufacturing the batteries, motors, and power
electronics that are at the heart of electric cars. There’s
still going to be a lot of work for engineers, but less

20 years.
INDUSTRIES
Lastly, the automotive industry, like many others, is changing rapidly:

Nanyang Technological University – Electric
Vehicle Advancement
Electric Vehicle Advancements: Quick Charging and More
Published Patent- US9112226 B2
Engineers at Nanyang Technological University (NTU) are right, ultra-fast charging batteries
could be available in two years. Researchers at NTU’s School of Materials Science and
Engineering have developed a rapid charging battery that can charge up to 70% capacity in
two minutes and full capacity in five minutes. That’s good news, especially for the electric
vehicle market. The better news is that it’s just a slight variation of existing lithium-ion (Li-ion)
battery technology, so Tesla
and other EV battery makers won’t need to retool their
production facilities. And to top it all off, these batteries are expected to deliver up to 10,000
charge cycles, about ten times more than conventional Li-ion batteries. If this is true, then
electric vehicle batteries could theoretically last 1,000,000 miles (1,610,000 km).
The trick is changing the chemistry of the anode, the negative terminal of the battery. Instead
of using graphite, the standard anode material in most Li-ion batteries, the new batteries use
a gel made of titanium-dioxide (TiO2) nanotubes. The gel allows chemical reactions to take
place much more quickly, giving the battery its fast charging ability. TiO2 is cheap and
abundant, so the gel won’t make the batteries too costly.

Siemens– Integrated Motor and Inverter
Integrated Motor and Inverter
Published Patent- EP2559587 A2
Taking a page from the consumer electronics industry, Siemens just
announced work on a new electric vehicle motor that integrates an
inverter right inside the motor housing. Electric vehicles run on DC
electricity produced by a battery, but AC motors tend to be more efficient,
so the inverter converts the battery’s DC output to AC before it gets to the
motor. Integrating the inverter into the motor reduces weight, size, and
complexity.
The company suggests that heat will be the biggest issue with this
integration. Both the motor and the inverter require cooling systems, and
Siemens has developed a method of using the same cooling system for
both. The cool water reaches the electronics first and then loops around to
cool the motor housing. The water itself acts as a thermal insulator
between the inverter and the motor.
