济南液压升降机机械液压助力回馈力比较好缺点是助力不会变化，有低速重，高速轻的问题，同时要消耗发动机的动力，虽然不多，但其实是要耗油的（理论上，实际可以忽略），电动助力，实际上是电提供的助力，理论上是车通电就有助力，优点是可以调成高速重，低速轻，并且基本不耗油（电也是烧出来的，但是电动助力的能耗要小得多）。
Ji'nan hydraulic elevator machinery hydraulic power steering force feedback better defect is power will not change, has low speed and heavy, high speed light problem, power at the same time to consumption of the engine, though not much, but in fact is to fuel consumption (in theory, the actual can be ignored), electric power, is actually providing power, theory is the car power with power, the utility model has the advantages of high speed and low speed can be transferred into a heavy, light, and basically no oil consumption (electricity is burned out, but the energy consumption of the electric power steering is much smaller).
缺点是电动助力分很多种，有一部分电动助力的指向的回馈不好，某些电动助力的车，转弯的回馈很差，基本上要靠驾驶员自己转回来。通过增加电池组，使用安全断网技术等方法，而这样做必然会提高生产成本。
The disadvantage is the electric power points are many, there is a part of the electric power steering directed feedback is not good, some electric power car, turning back is very poor, basically rely on the driver turn their back. By increasing the battery safe use broken network technique, and in so doing will increase the production cost.
正是因为锂电池技术带来的诸多弊端，目前国际上的先进研发机构已经将目标指向了另一个材料源——硫。据外媒报道，使用硫电池的济南液压升降机，其电容量最高可以达到锂电池的10倍，而硫的可获取量远大于锂。
It is precisely because the drawbacks of lithium battery technology, the advanced international R & D institutions have pointed to another material source -- sulfur. According to foreign media reports, Ji'nan hydraulic elevator using sulfur battery, 10 times the capacitance can reach the highest of lithium batteries, and can obtain the amount of sulfur is far greater than the lithium.
