30% cost reduction LG Chem development module package integration platform
Recently, according to foreign media reports, LG Chem has completed the development of its module package integration platform (referred to as MPI). The company hopes to use the new platform to integrate the cells directly into the battery pack instead of being built into the module first. Although LG Chem has not officially launched the platform, it may start sales soon after the development is completed.
It is reported that the number of cells that the new platform can hold is twice that of the traditional module platform, while its cost will be reduced by 30%, and the energy density will be increased by 10%. In the future, LG Chem will also need to adjust the design of the battery pack itself. For example, the overall stability is completely provided by the housing, and the design and installation of the thermal management system will also be affected by the battery-less module.
At the same time, LG Chem is also simplifying its battery supply to simplify production and improve efficiency. The company will provide two batteries, the standard battery is 300mm, and the long version is 500mm, replacing the previous soft-packed batteries tailored to OEM requirements.
For a long time, personalized size has been regarded as the advantage of soft-pack batteries. However, this requires constant adjustment of production methods. Re-adjusting a production line accurately reduces the scrap rate to a very low level, which may take up to a month. This process is expensive and inefficient. As automakers demand lower prices, they must reduce costs through standardized production. According to reports, Audi, Daimler and Renault will use batteries with a length of 300 to 400mm. Take Volkswagen’s MEB platform as an example. Its cell length is 550mm. Hyundai and its E-GMP platform are also expected to be equipped with long cells.
Editor's comment:
Currently, car companies’ demand for power batteries is mainly for battery suppliers to provide pre-manufactured battery modules, which are then assembled into battery packs in their own factories. For example, BMW cars mainly purchase prismatic batteries and assemble them into battery packs after purchasing the batteries. But no matter which method is adopted, when the battery pack enters the car, the distribution of the modules will affect the overall value of the battery. Then, if battery suppliers can assemble the modules themselves, it is no longer necessary for car companies to assemble the battery modules by themselves. From another point of view, this technology will also reduce battery costs, which is expected to push the price of electric vehicles down further.
