2004년 토요타에서 발표한 하이브리드 자동차 ‘프리우스’
1. 하이브리드 자동차(Hybrid Electric Vehicle, HEV)는..
하이브리드 자동차라는 개념은 20세기 초에 처음 등장했다. 당시는 내연기관 차량 개발의 초기단계였으므로 엔진 기술이 부족해서 고출력 엔진의 제조에 애를 먹고 있었다. 이 때,
Other Problems
· Swap Station Problems
- standardization among EV is not in place
· Batteries as Environmental Disadvantage
- battery manufacturing is an energy-intensive
process, involving hazardous chemicals
· Coal as Electricity Generator
- EV requires more coal mining and burning
Technical Issue
• Standardization (plug, phases, data protocol)
• Cros
vehicles from 2005. Especially, a traditional push strategy(producer-based method) was switched to a pull strategy(customer-based mothod) in the SCM part.
2. Trying to upgrade the quality through 6-sigma methodology
The 6-sigma movements started in earnest on November 1999. Hyundai Motor have trained 3500 experts of black belt and green belt, and attained several its goals;3800 projects, cost
1.Introduction
A fuel cell is a device that converts the chemical energy of a fuel (hydrogen, natural gas, methanol, gasoline, etc.) and an oxidant (air or oxygen) into electricity. A fuel cell operates like a battery. However, a fuel cell does not require recharging, it produces electricity and heat as long as fuel and an oxidizer are supplied.
Fuel cell construction generally consists
Global Trend towards Protecting the Ozone Layer
Global Convention and Protocol
The Vienna Convention (for the Protection of the Ozone Layer)
The Vienna Convention is a treaty concerning the customary international law on treaties between states. It codifies some groundwork of international law trying to protect the ozone layer. The US was the one the biggest producers and consumers of
