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 Vehicle1) No Emissions: Electric cars are 100 percent eco-
friendly 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.

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 focus on internal combustion engines than in the past 20 years.
Lastly, the automotive industry, like many others, is changing rapidly:• Nanyang Technological University (NTU), Singapore, is developing a rapid charging battery for EV.
• Siemens are working on a new motor that integrates an inverter right inside the motor housing of EV.
• Oak Ridge National Laboratory (ORNL) is working on an inverter that is optimized for size, weight and efficiency to provide power solution inside electric vehicle.
• Electric Power Research Institute (EPRI) is working on a set of smart charging protocols that would allow a smart grid to charge electric vehicles and fulfil ever growing demand.

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.

For sources of information, please refer to Appendix 1
Published Patent- EP2559587 A2Taking 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.
