The reference design improves battery security and efficiency, appropriate for autos, vitality storage, and industrial purposes.
The arrival of high-voltage battery methods in sectors like electrical mobility, renewable vitality storage, and industrial equipment has underscored the important significance of superior Battery Administration Methods (BMS). Particularly, Multi-Cell 36-48V BMS items have develop into indispensable in safeguarding these energy sources. They’re the sentinels of battery packs, repeatedly monitoring and managing the intricate dance of cost and discharge cycles throughout quite a few cells. By sustaining every cell inside optimum parameters, these methods not solely guarantee the protection and reliability of high-energy batteries but additionally considerably improve their longevity and efficiency. As we pivot to a extra electrified future, the position of a sturdy BMS turns into ever extra pivotal within the seamless operation and integration of high-voltage battery know-how in our day by day lives.
The TIDA-00792, a reference design from Texas Devices (TI), delivers a complete answer for the supervision, equalization, basic safeguarding, and capability measurement of lithium-ion or lithium-iron phosphate batteries starting from 12 to fifteen cells. Designed for industrial system integration, this circuit board is tailor-made for set up inside a protecting enclosure. It affords a reference design that simplifies the battery administration course of by precluding the necessity for coding by means of preset parameters. Furthermore, it incorporates high-side safety switching, facilitating easy communication in regards to the battery’s standing by way of PACK-referenced SMBus, even when the system is protected. The built-in cell balancing performance ensures an prolonged battery life by equalizing the cost throughout all cells, whereas the fuel gauging characteristic estimates the system’s run time.Â
This technique design is tailor-made for a 48-V nominal lithium-ion or lithium-iron-phosphate battery administration system (BMS) that operates successfully throughout a voltage vary of roughly 36 V to 50 V. The design idea revolves round a flexible board, which may be selectively populated to fulfill the wants of assorted methods. These methods might require the same battery configuration however have completely different present necessities, and this design accommodates such variability with out the need for type issue optimization.
Essential operational parameters comparable to cell voltage, pack present, and temperature are regularly measured and monitored to make sure the battery stays inside protected working situations. Any deviations set off alerts to a bunch system and may activate protecting protocols to halt charging or discharging as wanted. Using high-side N-channel FETs for defense switching facilitates a wide array of FETs and ensures uninterrupted low-side communication, even throughout protecting occasions. The state-of-charge is precisely gauged utilizing compensated end-of-discharge voltage (CEDV) or end-of-discharge voltage (EDV) strategies. All security limits are predefined to bypass the necessity for extra coding. This versatile design is good for battery packs in numerous purposes, from industrial tools and home equipment to e-mobility, stationary vitality storage, and UPS methods, whether or not used as-is or as a template for a custom-shaped answer.
TI have examined this reference design. It comes with a Invoice of Supplies (BOM), Schematic, and so on. You’ll find extra knowledge in regards to the reference design on the corporate’s web site. To learn extra about this reference design, click on right here.
