A battery pack, which is an assembly of battery cells electrically organised in a row by column matrix configuration, is under the control of a battery management system (BMS), a piece of technology designed to deliver a targeted range of voltage and current for a period of time against anticipated load scenarios.
A BMS keeps track of the temperatures throughout the pack and controls a number of valves to keep the overall battery temperature within a certain range for optimum battery performance.
The Global single chip BMS( Battery Management System) market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Qorvo Introduces Industry’s First Single-Chip Intelligent Battery Management Solutions for 20-Cell Systems.The Power Application Controller (PAC) devices, model numbers PAC22140 and PAC25140.
The two PACs are the first single-chip solutions in the industry to accommodate battery packs with up to 20 series-connected cells. In order to allow intelligent battery management solutions (BMS) for a variety of industrial, e-mobility, and battery backup applications, these products make use of an intelligent motor control basis.
The highly integrated PAC22140 and PAC25140 reduce time to market while saving designers more than 50% of PCB area and 30% of the overall BOM cost by using Qorvo’s hardware and firmware ecosystem.
With a 32-bit Arm Cortex M0 or M4F microcontroller, the devices incorporate the necessary analogue and power management peripherals and offer cell balancing, monitoring, and protection for battery packs with 10s to 20s of runtime.
Access to several analogue and digital peripherals needed to handle high-cell-count battery packs is made possible by the PAC22140 and PAC25140. Among these are a differential amplifier with configurable gain, many 16-bit Sigma-Delta ADCs for current and voltage sensing, and a 10-bit SAR ADC.
The device is powered by a single-supply 145V-buck DC/DC controller, which creates a 5V system rail and supports the charge and discharge FET drivers with an integrated charge pump.
