To achieve better energy storage technology, the world needs a better battery—and Analog Devices has been making important strides in delivering the electronics to enable one. The breakthroughs can be traced back to our improvements in battery management systems (BMS). Building on our leadership in wired BMS, we have recently developed a groundbreaking wireless BMS (wBMS) technology, that eliminates the need for the battery wire harness. Wireless battery management systems provide an ideal path for OEMs to scale up the electric vehicle fleets, enabling a flexible and reusable platform that saves costs, while providing data that leads the life of the battery cell modules into their second life.
Together, these advancements are making battery second-life applications (like energy storage systems or ESS) more feasible energy storage technology than ever before. ESS allows renewable energy sources (wind turbines, solar panels, etc.) to capture energy, store it and support the grid during peak operation. This implementation is further improved by the robust data-collection capabilities of our wBMS sensors. Before a battery is repurposed, the seller can use that data to generate a state-of-health history: how many times did the EV owner completely or partially charge and discharge the battery; was the EV ever in an accident; what do the vehicle’s maintenance records indicate? Such granular health monitoring can also be applied in places where data has been logistically impossible to collect.
In the end, Analog Devices has helped answer two massive, global energy questions with a single, better battery. It’s now within reach to repurpose EV batteries to store sustainable power in the developing world, a fact that also makes EVs themselves more economically viable. To us, it’s just another mile marker on our continuing journey to power the breakthroughs that make human life better.
