From another point of view, the design of the whole vehicle is simpler, the arrangement of components is more flexible, the efficiency is higher, the speed is faster, and the cost is lower. Look, isn’t it very “Musk”? The “efficiency” and “cost” of “first principles” are revealed everywhere. The protection level is improved and the safety is higher. The maintenance-free is mentioned above, which will bring another advantage: the design of the power distribution box can be fully sealed and the protection level is higher. For example, the power distribution box used to be a plastic box, covered with a plastic cover and a few buckles, the protection may only be IP54, but now I fully seal it, and it is IP67 or IP69 at once, so even if the engine compartment is flooded with water, there is no problem. , which can ensure the safety of vehicle power supply, which is especially important for trams. For users, the power distribution box will not be broken after wading, which reduces maintenance costs.
