In addition to the electric car is a hot topic of science and technology industry, the subject of electric locomotive, before GOGORO appeared in Taiwan and the global technology industry, and a lot more space of the discussion. Previous GOGORO news release said the company has made the world first about the battery electric locomotive 2271 UL certification, this also means that even electric locomotive, the same as the electric vehicles, all over the world have relevant specification need to meet to in the local market sales.
UL energy and power of science and technology business development manager Chen Limin pointed out that by electric locomotive, the most critical certification scope, should be electrical safety, in terms of specification level, is quite familiar in the automotive electronics industry functional safety standard ISO 26262, and it was unanimous on the two large area of European market. In the past, the general cars powered by internal combustion engine, the power calculation for the "power", but in the field of electric vehicles, "w" is the power unit, the ratio of the two units is about 45.7 1:7, in other words, one horsepower equals 745.7 watts, and general market are reduced to 750 watts.
Chen Limin talked about, the classification of the electric locomotive has been the most headache problem in recent years, the market, but once established classification standards, subsequent standards can be made, of course, electrical safety and risk standard, etc., it was the same as that in the European market, for example, generally can be divided into 1000 w, 4000 w and 4000 w above three types, such as the third class and can be divided into less than or equal to 11000 watts, less than or equal to 35000 watts, and the level of more than 35000 w, if in Taiwan, and we know the speed of g is the same.
Chen Limin explanation, electrical safety is placed in key position, is one of the reasons is 48 v of dc electric arc voltage is quite powerful, it can achieve high temperature enough to metal evaporation, rather than metal distortion or deformation is only to be so simple, further said that as long as the problems of the electric circuit, dc arc the probability is quite high, great danger for the personal security, so it has to do with ordinary people for the battery itself is safe, there are quite a big gap.
And in the past, the basic functional safety of vehicles ISO 26262 into the electric locomotive, for electric locomotive industry, also is faced with the problem of certification for too long? Chen Limin goes further, as a result of the electric locomotive with four-wheel electric vehicle on the power, there is still a certain gap, in simple terms, the electrical system in the electric locomotive is relatively simple, in the cognizance of ISO 26262, the disaster caused by the relatively small, so the certification is relatively easy, also need not particularly worried about the authentication time is too long.
