4 What is an E-bus? E-bus is a regular bus, which instead of being driven by a polluting diesel engine, is being equipped and driven by an electric motor. The electricity for the electric motor is supplied by rechargeable batteries or ultra capacitors (UC). The E-bus does not pollute the air and significantly saves energy.

Slide 5

5 Why E-bus? World wide non-conciliatory growing demand for cleaner personal and public transportation Readiness of governments to invest enormous capital for any reduction of the pollution No doubt the trend of the future Electric engines are much more efficient than diesels. Interesting business opportunity Great saving in energy cost Great saving in bus maintenance cost

Slide 6

6 Energy Saving Fuel consumption of a diesel city bus is 1.3 2.5 km/liter. Electric consumption (with A/C) is 1 1.2 kWh/km. In most of the worlds countries, operation of E-bus might save the operators significant sums of money due to the much lower cost of 1.2 kWh vs. the cost of fuel. Actually the most important task and target is to reduce the pollution in side the cities. Saving of energy cost is just an extra benefit.

Slide 7

7 Maintenance Saving The maintenance cost of an E-bus is significantly lower than the diesel buses. No internal combustion engine No Gear box No exhaust system and no catalytic convertor No cooling system and radiators No fuel injection system No oil, fuel and air filters required. No timing and driving belts

Slide 8

8 Pollution Reduction Ideal burning of diesel produces 2.6 kg of CO 2 per 1liter or 2.2 kg CO 2 per 1km. Production of 1kWh produces 0.8kg CO 2 in coal & oil power stations and 0.52kg CO 2 in gas turbine power stations. E-bus will not pollute at all in the city, and will produce only about 1/3 CO 2 vs. the diesel buses.

Slide 9

9 Battery based E-bus A more common technology. At least 10 serious Chinese bus producers are offering this technology. About 1.31.5 tons of Li-Ion batteries, 5-7 charging hours, provide up to 140km with A/C. One of the Chinese E-buses producers offers 4 tons Load of batteries in order to provide 200 250km between charging. Requires individual charging units for each E-bus.

Slide 12

12 UC based E-bus Contrary to passengers cars, city buses are traveling in fixed courses. This enable effective and relatively low cost electrical charging infrastructure. The city line terminal (initial bus stop) is equipped with automatic charging system. The new technology of UC enable using the bus stopping for passengers boarding for the charging.

Slide 16

16 UC E-bus 2 nd generation 5-8 minutes charging in the terminal (beginning of the line), will enable driving 1030km w/o charging. 480kg UC will enable 10km between charging 960kg UC will enable 20km between charging 1,440kg UC will enable 30km between charging Actually the UC E-bus can drive around the clock with out any distance limitations. No need for an individual charging system for each E-bus. A few charging stations in the night parking lot and in each line end will do.

Slide 17

17 Advantages of UC Lower curb weight Higher load capacity Lower E-bus cost vs. batteries one Regular inner city bus design Lower investment in infrastructure (only one charging unit for each city line) No explosion risk in cases of impact or quick discharge Low temperatures does not effect the performance, neither the efficiency and output of the UC. Can perform with full capacity even at - 40c. No need to warm batteries storage cabins Longer life-span

Slide 18

18 UC Technology Successfully operated in Shanghais public transportation for 5 years 5,000,000 km accumulated. Great Success while operating during the great EXPO in Shanghai 2010. Now, upon achieving full compliance to the EU standards (WBTA), will start exporting to the West. Future UC developments could be integrated into the current models and will not require new. Safer than any other bus (Gas, Diesel & Batteries) as the UC are based on water.

31 China is preceding the West in the clean public transportation area. Many of Chinas cities are already successfully operating E-buses as part of the city public transportation system. This trend is picking up rapidly. E-buses in China is a fact. Production of E-buses in China

Slide 32

32 Production of E-buses in China Production of a bus requires a lot of manual work. A skilled Chinese worker earns about $500 per month (10 times cheaper than in Europe). This might be one of the major reasons for the huge difference in the buses costs. The UC E-bus is produced in one of the worlds biggest bus factory and complies with the full European standards and regulations (WVTA), using top Western major parts (such as Siemens electric motors, German ZF steering and axles).
