Modern electrified vehicles have very dense battery packs. These packs are comprised of dozens of lithium-ion cells stacked together in a vehicle chassis. These high-density battery packs are relying on sophisticated monitoring and communication interfaces in order to detect faults and to have the cells work efficiently together, effectively increasing the battery life. There are two Battery Management techniques in use: wired and wireless. A typical Battery management scheme has each battery cell, or small group of cells, connected to high accuracy monitors. In the wired Battery Management scenario, the cell monitors are wired to each other and connected to a Central Processing Unit (CPU). The CPU takes the incoming information from the cell monitors and incorporates the data in to a track battery performance and battery health.Wireless Battery Management uses a wireless protocol like Low Energy Bluetooth to replace the wired interconnects. The potential high volume applications for Wireless Battery Management devices requires a low cost high throughput device test solution. This paper will describe Ultra-Flex instruments need to test these devices.
