In conclusion, it is proved that the SVD-AECKF algorithm can improve the joint state estimation of lithium-ion batteries and increase the estimation efficiency and accuracy. This study provides a theoretical basis for providing battery condition monitoring to ensure that drivers can drive the new energy vehicles safely.
The recovery processes of decommissioned lithium batteries are mainly divided into physicochemical method, pyrometallurgy, hydrometallurgy and new biotechnology. The physicochemical method is to use the physicochemical reaction process to recycle the decommissioned lithium batteries.
Recupyl company’s recycling process of decommissioned lithium batteries is carried out under the protection of inert gas mixture. The decommissioned lithium batteries are crushed and separated by magnetic separation to obtain the valuable metals needed.
The physicochemical method is to use the physicochemical reaction process to recycle the decommissioned lithium batteries. The main techniques include a mechanical grinding method and flotation method.
The decommissioned lithium batteries are crushed and separated by magnetic separation to obtain the valuable metals needed. Some metal ions were leached with LiOH solution, and then insoluble metal ions were leached with strong acid. The precipitates of other metals were obtained by adding Na 2 CO 3.
At the machinery level a multi-level ML study was presented, which allows evaluating the impact of varying process parameters on battery properties (including performance) distributions.
