Hyundai Avante Hybrid (Elantra) 2009 commercial (korea)

현대자동차 아반떼 LPi 하이브리드 광고 Hyundai presented the LPI Hybrid at the 2009 Seoul Motor Show, and sales began as the Avante "LPI Hybrid" in the South Korean market in July 2009. The LPI Hybrid (liquefied petroleum injected) is a mild hybrid and is the world's first hybrid electric vehicle to be powered by an internal combustion engine built to run on liquefied petroleum gas (LPG) as a fuel. Hyundai developed the technology and all key components in the LPI Hybrid, together with its local partners including the electric motor, battery and low DC/DC converter. The lithium-ion polymer batteries, for which the LPI Hybrid is the first hybrid to adopt, differ from lithium-ion batteries in the medium used for the battery's chemical reaction, as the latter use liquid or gel electrolyte as the conduit by which electrons pass between the anodes and cathodes, while lithium-polymer batteries, which Korean company LG Chem has been making for various applications since 2005, use a dry polymer that is considered more stable and fire-resistant than liquid. If the cells in a lithium-ion battery overheat, the liquid electrolyte can leak and cause a fire, which makes lithium-polymer batteries safer, and improves battery life under high-temperature conditions. The batteries used in the Hyundai Elantra LPI HEV also hold a more dense charge, which means that they can be more compact for an equivalent charge, and their self-discharge rate is said to be one-third of nickel-metal hydride batteries.
