Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.

Toyota sells six of 10 of hybrids in California

In an apparent shot back at Ford's increasing market share of electrified vehicles and claim that it accepts more Prius trade-ins for its own hybrids than any other car, Toyota has flexed a muscle and played the numbers game to put the Blue Oval in its place.
Leaning on its hybrid market dominance in California, the Japanese automaker stated that six out of 10 hybrids sold in the Golden State are Toyota models. And it keeps coming: Year-to-date through May 2013, Toyota sold five times more hybrids than Ford. One of every two hybrids in California is a Prius model. In addition, Toyota notes that it has sold 1.5 million Prius vehicles in the US, 90-percent of which are still on the road today.

China sticking to its guns on EVs for the future

Automakers are obviously free to develop whatever next-gen, zero-emissions tech that they want. However, if a company wants to get on the good side of the Chinese government, that strategy better include some plug-in vehicles. The authorities there are lending major support to plug-ins at the moment, and its forcing the auto industry to play along. According to Bloomberg, Toyota, Volkswagen, Hyundai, and BMW are all launching dedicated EV brands with their joint venture partners, and as many as 40 electric models could hit the Chinese market this year alone. However, analysts don't think the vehicles are going to sell well. Instead, the launches are essentially a way for companies to play nice with the government and help get the approval to build factories in the country. Take Toyota as an example. The company is pushing the future of hydrogen hard with promotional films for the Mirai and engineers talking down fast-charging EVs. Still, the Japanese automaker is getting ready to launch two EV brands in China with its joint venture partners, according to Bloomberg. China's push for alternative fuels has been happening for a while, but it really kicked into high gear last year. The government has set a goal to improve fleet-wide economy by 40 percent by the end of the decade in order to spend less importing oil and for the population's health. The plan has shown some success so far with hybrid and EV sales growing early in 2015.
