Introduction to Battery Cooling Systems for New Energy Vehicles

With the advancement of modern technology, various types of electric vehicle (EV) battery cooling systems are being applied across different sectors. The battery pack, which is the main energy storage component of an electric vehicle, plays a crucial role and directly impacts the vehicle's performance.

 

Lithium-ion batteries, known for their excellent power output characteristics and long lifespan, are widely used in EV battery packs. However, lithium-ion batteries are sensitive to temperature changes, especially high-capacity and high-power lithium-ion batteries used in vehicles. During different driving conditions, the battery discharges at varying rates, leading to uneven heat generation due to time accumulation and spatial effects. Due to the dense arrangement of battery cells, heat tends to accumulate more in the central areas than at the edges, resulting in temperature imbalances among the cells. This can exacerbate inconsistencies in internal resistance and capacity of the battery modules and cells. Prolonged accumulation of heat can cause overcharging or over-discharging of some cells, affecting battery life and performance, and posing safety risks. To extend the battery's lifespan and driving range, effective cooling solutions are necessary. Currently,  power battery cooling solution is a promising trend.

How does a CNC machining center ensure precision for mass-produced products?

Precision is one of the most important indicators to evaluate the processing performance of a CNC machining center . The processing precision and processing errors have a great impact on the quality of the processed parts. How can a CNC machining center ensure the precision of mass-produced products? The most commonly used processing method in the CNC machining industry is the trial cutting method. The trial cutting method is to try cutting, measure the size, adjust the cutting depth of the tool, cut again, and repeat the process until the required size is achieved. This method can ensure that the error is within a reasonable control range, but it is quite cumbersome and has a low production efficiency. It is mainly used for single-piece and small batch production. In mass automated production, CNC machining centers can achieve the required size by adjusting the relative positions of the machine tool, fixture, workpiece, and cutting tool in advance, thus achieving the goal of ensuring

How to deal with the plastic injection molding raw material is not filled?

图片
Electric injection molding machine in the production of injection mold will encounter the situation of injection molding is not filled, there is a lack of glue at the bone position right Angle and fuse connection, here to share some experience. Analysis of glue injection is not filled: 1. The trapped air in the bone position makes the injection molding machine fill up. 2. The filling of the injection molding machine caused by the glue welding line is not filled. Reason analysis of glue injection is not filled: When the injection molding machine is working, the mold gluing method is two-point gluing, and the injection speed is too fast, which is easy to cause the gas trapped at the right Angle of the bone position and cause the filling dissatisfaction; If the injection speed is too slow, it is easy to fill the fuse at the end of the flow. The solution: Multistage injection molding and position switching. In the first stage, the medium speed filling channel was used to pass

Control of Injection Molding Parts Processing Temperature

图片
There are many kinds of plastic, many plastic materials melting time are different, because the plastic does not have a specific melting point, the so-called melting point is a melting state of the temperature segment, the structure and composition of the plastic molecular chain is different, so the impact on its fluidity is also different, then in the production of injection parts manufacturers in the injection parts processing temperature control is also very important. 1. Mold temperature Some plastic materials due to high crystallization temperature, slow crystallization speed, need higher mold temperature, some due to control size and deformation, or the need for demoulding, to higher temperature or lower temperature, such as PC generally requires more than 60 degrees, and PPS in order to achieve a better appearance and improve fluidity, mold temperature sometimes needs more than 160 degrees, Therefore, the mold temperature has an inestimable effect on improving the appearanc
