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.

Shortcomings of Current Technologies:

Nanyang Technological University – Electric Vehicle Advancement

Patent Searching | Research and Analytics | Patent Prosecution/Preparation Support | Litigation and E-Discovery | IP Valuation | Patent Portfolio Watch32For sources of information, please refer to Appendix 1

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.

Electric Vehicle Advancements: Quick Charging and More

Siemens– Integrated Motor and Inverter



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.
