Controlling Battery Functions and Communications
With decades of experience and a vast amount of expertise, EaglePicher is an industry leader when it comes to providing customers with battery management systems for even the most demanding applications. We have designed battery management systems for customers in the commercial, space, aviation, military and other markets. Our designs cover the gamut — from low-power systems with low quiescent power draw to high-power megawatt class 1000 volt energy storage systems.
EaglePicher’s electronics provide safe, high-performance solutions for real-world applications. We utilize smart management electronics to enhance the capability and safety of your battery management system. We typically refer to the combination of battery cells with battery management system software and protective electronics as a battery system. EaglePicher believes it is better to recommend complete solutions, and that is why we develop the electronics package simultaneously with the design of the rest of your battery system.
Our battery management systems include the electronics and software that gets “wrapped around” EaglePicher's battery cells. In general, a battery management system can provide insight into the state of a battery and provides information on optimal and safe usage of a battery. The largest contributor to safety events for lithium-ion cells is overcharging; this is why lithium-ion batteries have more complex electronics than other cell chemistries. An effective battery management system can improve the safety of lithium-ion cells by decreasing overcharging. Active and passive protection hardware can also be used in conjunction with battery management system to enable optimal performance of the battery.
EaglePicher's battery management system functions and protections include charge and discharge control; voltage, current and temperature telemetry; state of charge, state of health and failure status; and voltage, current, temperature, leakage current and short detection fault protection. These systems also include redundancies to ensure continued operation using microprocessors with built in dual memory and processor cores to verify data integratation and auto correction, radiation hardened processors and the option of an analog redundant parallel monitoring.

What does a battery management system do?
A battery management system of BMS optimizes a battery’s performance over long, high-cycle life missions. Batteries can be equipped with battery management electronics within the battery design. The electronics provide autonomous and commanded cell equalization during the charge portion of the cycle at an individual cell basis. This provides cell uniformity within the battery assembly and extends the performance and life of the battery.
