虽然通用今年初宣布计划在2010年推出采用锂离子电池组的插入式混合动力车，但丰田承认锂离子电池技术应用于量产车目前仍很危险。丰田将不再急于生产锂电池。丰田负责研发的副总裁Kazuo Okamoto在接受《汽车新闻》采访时承认推迟采用锂电池主要是由于安全问题，他透露工程师仍将集中精力提高现行的镍金属电池的使用效能，锂电池比镍金属电池体积更小也更轻，但可能会出现过热，着火甚至爆炸。Okamoto并没有透露新电池推出的时间表，他解释说目前仍有很多问题有待解决。 Toyota not rushing lithium-ion tech,focusing on plug-ins Toyota admits lithium ion battery technology is still too hazardous to use in its production cars despite GM announcing earlier this year that it expects to have a plug-in hybrid vehicle with lithium batteries by the end of the decade. The Japanese giant doesn’t want to rush out products with lithium batteries. The biggest factor holding it back is safety fears, revealed Toyota’s executive vice president for R&D Kazuo Okamoto during an interview with Automotive News. Instead, engineers will concentrate on improving the efficiency of current nickel-metal hydride technology. Lithium ion batteries are smaller and lighter than nickel-metal hydride but they tend to overheat and can even catch on fire. Okamoto wasn’t willing to give a timeline for the introduction of the new batteries, explaining that there are still a lot of problems to solve. |
