Product overview
Description
The battery management system (BMS) is a fast-growing application pervading several fields of the electronic industry including automotive and industrial markets.
To support fast evaluation and meet stringent time-to-market for BMS solutions, the AutoDevKit ecosystem has been extended to include a specific cylindrical battery holder.
The purpose of this extension is to quickly create a battery pack to evaluate ST BMS solution based on the AEK-POW-BMS63EN analog front end node hosting the L9963E and the AEK-COM-ISOSPI1 ISOSPI transceiver hosting the L9963T.
You can test the battery pack also using our latest BMS evaluation boards: AEK-POW-BMSWTX and AEK-POW-BMSNOTX.
The AEK-POW-BMSHOLD battery holder contains a maximum of 14 cells, all connected in series, and a dedicated slot and connector for our range of BMS evaluation boards.
To build a complete battery pack in both centralized or dual-ring topologies, you can stack up to three / four AEK-POW-BSMHOLD kits (the limit is the stackable weight). A separate bag inside the kit package contains six M3x12 mm pan steel screws, four M3x25 mm plus six M3x30 mm hexagonal steel spacers. These elements can be used to mount another AEK-POW-BMSHOLD layer.
The AEK-POW-BMSHOLD has a long satin ribbon tied to a buttonhole on the plexiglass used to support easy battery removal.
The internal wiring of the featured 4-pole mammoth connector allows adding a sensing resistor between pin 2 and pin 3. Pin 1 and pin 4 are, respectively, the positive and the negative terminals of the mockup. For demo purposes, a 100 mΩ, 10 W, ±1% precision resistor is included in the kit package.
The AEK-POW-BMS63EN node boards have to be connected to the crimped central connector provided in the AEK-POW-BMSHOLD kit.
The connector is organized as follows: pin 1 is the cell VBAT, pin 2 to 16 are dedicated to the battery connections, pins 17 and 18 are ext Ground, pins 19 and 20 are ISenseP and ISenseM, pins 21 to 30 are dedicated to NTCs for temperature sensing.
The even numbers with yellow cables are NTC-, whereas the odd numbers with blue cables are NTC+. Five 10 kΩ, ±1% tolerance NTC thermistors are provided in the kit.
The AEK-POW-BMSHOLD kit supports INR 18650 battery type. The estimation of SoC and SoH included in AutoDevKit Studio is computed through an extended kalman filter with characterization data coming from INR 18650 MJ1 batteries by LG.
