5 Summary

As the life support system in new energy vehicle collision scenarios, CPM has its core value in providing power from backup battery to unlock the doors after the main battery fails, building the last line of defense for a passenger escape. With the popularity of E-latch and upgrade of safety regulations, CPM has become a necessary safety requirement, and the market size is expected to show a steady growth trend. In the future, CPM develops toward higher integration, longer lifespan and lower cost solutions.
