Battery management systems

The battery has inched its way into our modern lives and is now so ubiquitous to how we live that they are almost invisible and often go without much thought. Most of how we communicate, gather our news, are entertained, and increasingly, how we transport ourselves relies on a battery of some sort.

Increasingly, it has become more important that we not discard to the landfills these little givers of energy. To do this, we need to be able to safely regenerate the energy inside these batteries and keep them in service, almost indefinitely. Today’s Battery Management Systems (BMS) have been developed to help us do exactly that.

The BMS manages the recharging of batteries by controlling load environment, monitoring battery state, and accordingly balancing the charging. A battery management system is useful for ensuring prolonged life of batteries, preventing battery damage due to overcharging and voltage fluctuations, managing optimal state of charging for the battery and facilitating BMS interfaces with host application to provide real-time information regarding battery health. BMS follows three types of topologies, which are distributed, centralized and modular. Distributed BMS has a single communication cable controller and battery; a cell board is installed at each cell. Centralized BMS has a single controller, which is connected to battery cells with the help of communication wires. Modular BMS has multiple controllers that handle certain number of cells and communicate with each other.

The global battery management system market is primarily segmented on the basis of verticals into automotive, energy, telecom and drones.

  • Automotive includes EVs, HEVs, PHEVs, BEV, racing vehicles and electric heavy vehicles, golf cart, medical mobility vehicles, and e-recreational vehicles
  • Telecom is dominated by industrial UPS systems
  • Energy includes utility/grid, solar/wind, portable battery packs, energy storage systems, and UPS
  • Drones are both personal and industrial in nature

Power beads for high-efficiency computing

The increasing power requirements of today’s micro-processors, ASICs, FPGAs and memory modules, coupled with a lowering of their operating voltage, continues to push operating currents higher and higher. This trend, along with the need for improved efficiency and higher power density, demands smaller, more tightly toleranced and efficient magnetic components that are suitable for the complex power delivery topologies. The Pulse power bead inductor product family has been instrumental in these developments and it perfectly suited for these requirements.

The Pulse power bead uses a gapped-ferrite core structure and a low winding resistance, down to 120μOhms. The Ferrite cores have roughly 20 times lower core loss than traditional solutions for a given flux density and frequency. This property allows for a dramatic reduction in core losses. In addition, ferrite, unlike some traditional solutions, is not susceptible to thermal aging, which is a process by which the binder in the cores breaks down at elevated temperatures, causing an increase in core losses as well as more heat and a thermal runaway condition.

Pulse has been on the leading edge of supplying this type of high efficiency inductor since the development of the first Intel VR specification. We continue to focus on these products by extending our product line from the single phase, high current models, to our multi-phase integrated and coupled bead inductors for today’s highest efficiency demands.

While starting life as a product dedicated for the server compute space, the Pulse power beads have found additional applications where the use of high load switching frequencies and thermal performance are just as demanding. Some of these alternate applications include SMP modules, laptop and mobile computing, graphics cards, datacom and telecom switching gear and storage systems utilizing high power ASICs and FPGAs.
