Should the new energy vehicle motor use ATF oil or self-developed?
Why do some new energy vehicle motors use ATF oil? Transmission oil, referred to as ATF oil, is essentially a hydraulic oil, which exists in various components of the gearbox and plays the functions of power transmission, lubrication, anti-wear, cooling and so on. In the motor, some brands will continue to use the mainstream ATF oil on the market, but as an OEM, it is best to develop their own motor special oil from a technical point of view, because ATF oil fully considers the blistering characteristics of torque converter agitation, because the transmission oil is subjected to strong shear force, such as poor shear stability of the oil, the torque converter will slip, reducing the transmission efficiency of the torque converter. But the internal oil of the motor is mainly used for cooling, do not need to consider the automatic transmission so large shear force, and there is no excessive bubble effect, the most deadly is some ATF oil, the formula used to inhibit the bubble characteristics will cause potential damage to the motor cable, insulating paper, silicon steel sheet plating, so many companies choose to develop their own motor special oil.
From this point of view, the maintenance of electric EVs and hybrid HEVs, once not maintained in professional 4S stores, the manufacturer cancels the warranty, which becomes some of the reasons. Recently, everyone seems to be particularly concerned about the topic of maintenance of new energy vehicles, which must be related to the professionalism of oil. Then for the premium rate of new energy vehicle maintenance, how can manufacturers defend and do high, how can customers maintain freely and get benefits, and how to upgrade and improve durability from a technical perspective. They will all be larger topics, which are open and there are no strict answers at the moment. #Car Science Sticker##Understand Che Lao Wang##New Energy Vehicle##新能源车保养#
