The main influence factors of SOC estimation include: charge and discharge current, environment temperature and battery SOH, the specific discussion respectively as follow. 2.1 Charge and Discharge Current In the conditions that power battery internal active material keep equal amount, the greater the charge and discharge current, the lower utilization degree of active material, and the smaller of power battery capacity, so the power battery capacity during different current conditions are not consistent with rated capacity.
Using Peukert equation [2, 3] for correction, Peukert equation is as follows: (2) Hereinto, as discharge current (A); as discharge time at current (h); as Peukert constant, relate to the internal structure of battery; as constant, relate to the active material.

In most cases mechanical failures originate from the surface and subsurface of materials.
Because the dynamic pressure is dominant and plastic deformation is weak on the material surface when the steel shots bombard relatively hard materials [11].

It is well-known the polyesters that prepared by treating a diol (saturated/unsaturated) with saturated and/or unsaturated dicarboxylic acids/anhydrides are valuable materials in polymer technologies.
Experimental Materials.
As a result, the outside materials was not easy to encroach to the surface of the coating, so the weather resistance of the coating was improved.

This often marks real advance in science and technology."
Cultural development urgently need convenient writing materials to replace bamboo slips and silk.
Inexpensive writing materials is the development trend, so people invented "paper” through research. 2. to create topics from existing theories, technologies and products.
Namely using related technology "mechatronics" and "biological materials" constructs new efficient "artificial kidney-type filter" similar to work process of artificial kidneys, its principle is shown in figure 3.
