Smart Battery Tray – Integrated Cell-Level Thermal Control<\/p>\n

\n\t\t\tSBTR Series\t<\/h1>\n\t

Arbin’s SBTR gives every channel its own closed-loop thermoelectric cooler, so fast-charge and high-rate discharge testing on 18650, 21700, and large-format 4680-class cells stays accurate at up to 200A per cell, without waiting on a shared environmental chamber to catch up.<\/p>\n\t\t\t\n\t\t\t\t\t\t\t\ube0c\ub85c\uc154 \ub2e4\uc6b4\ub85c\ub4dc\n\t\t\t\t\t<\/a>\n\t\t\t\n\t\t\t\t\t\t\t\uacac\uc801 \ubc1b\uae30\n\t\t\t\t\t<\/a>\n

Scalable channel density in a compact, air-cooled footprint, with open Python and C# API for the automation you already run.<\/p>\n

\n\t\t\tHighlights of the SBTR Series\t<\/h2>\n\t

Four thermal-control innovations that turn temperature from a chamber condition into a precisely controlled test parameter for every cell.<\/p>\n

\n\t\t\tMarket Leading Specifications\t<\/h2>\n\t

100 ppm precision, 24-bit resolution<\/p>\n

\n\t\t\tSee cell behavior – not tester uncertainty\t<\/h2>\n\t

Voltage and current measurement precision reaches 100 ppm (\u00b10.01% FSR) and 200ppm (\u00b10.02%) accuracy<\/strong>. 24-bit resolution provides fine control and measurement granularity across each current range.<\/p>\n

Subtle shifts in resistance, voltage response, and coulombic efficiency remain visible and repeatable-helping you distinguish real cell behavior from measurement noise.<\/p>\n

\n\t\t\tIndependent Cell-Level Thermal Control\t<\/h2>\n\t

dedicated TEC for every cell<\/p>\n

\n\t\t\tControl the cell – not just the chamber\t<\/h2>\n\tEvery cell position has its own thermoelectric module with closed-loop temperature feedback and independent control. Each cell can actively heat or cool in response to changing test conditions.\nThis keeps the programmed temperature focused on the individual cell rather than relying on the ambient temperature surrounding an entire tray.\n

\n\t\t\tImproved Test Repeatability\t<\/h2>\n\t

stable temperature throughout cycling<\/p>\n

\n\t\t\tSeparate cell behavior from thermal variability\t<\/h2>\n\tTemperature directly influences capacity, internal resistance, cycle life, and fast-charge performance. SBTR actively maintains the cell’s thermal condition while the electrical load changes.\nReducing uncontrolled temperature variation makes results more repeatable and gives greater confidence that measured differences come from the cell itself.\n

\n\t\t\tBuilt-In Safety Features\t<\/h2>\n\t

safety monitoring for every channel<\/p>\n

\n\t\t\tOnboard computation and independent safety\t<\/h2>\n\t

Each channel computes capacity, energy, internal resistance, and efficiency in real time. Voltage, current, and temperature are all checked against safety limits independently of the test control loop.<\/p>\nMetrics arrive already calculated, and a channel can be stopped on safety regardless of what the test controller is doing.\n

\n\t\t\tChamber-level cooling was never built for this\t<\/h1>\n\t

A shared environmental chamber conditions an entire tray to one setpoint. When cells are pushed to high current, that setpoint stops meaning much for any single cell<\/p>\n \n Traditional Approach\n

\n Chamber-Only Testing\n <\/h3>\n \u00d7\n One setpoint for every cell in the tray, regardless of individual load.\n \u00d7\n Slow to respond to a single cell’s heat generation during fast charge.\n \u00d7\n Neighboring cells can influence each other’s thermal conditions.\n \u00d7\n Requires a large environmental chamber to control the complete test matrix.\n \n Arbin Approach\n

\n Arbin SBTR\n <\/h3>\n \u2713\n Dedicated TEC and closed-loop temperature control for every individual cell.\n \u2713\n Machined-aluminum interface provides fast, direct thermal coupling to each cell.\n \u2713\n Each cell maintains its programmed temperature independently of neighboring cells.\n \u2713\n Reduces dependence on large environmental chambers for localized temperature control.\n \n Measured Thermal Performance\n

\n Hold the temperature you programmed – even while the cell is generating heat\n <\/h2>\n \n SBTR does more than condition the air around a battery. Each cell is thermally\n coupled directly to its own TEC, allowing the system to actively remove or add\n heat as electrical loading changes.\n \n \n 44 W\n Maximum measured controllable heat load per cell at +40\u00b0C \u0394T\n 33 W\n Controllable heat load per cell at +20\u00b0C \u0394T\n 3.6C\n High-rate 21700 charge demonstrated under active thermal control\n \n \n Heat Rejection Capability\n

\n Active control as cell heat increases\n <\/h3>\n \n The SBTR was tested to determine how much cell-generated heat could be\n continuously regulated while maintaining the programmed TEC setpoint.\n \n \n +40\u00b0C \u0394T\n 44 W \/ cell\n \n +30\u00b0C \u0394T\n 39 W \/ cell\n \n +20\u00b0C \u0394T\n 33 W \/ cell\n \n +10\u00b0C \u0394T\n 27 W \/ cell\n \u0394T = TEC setpoint minus ambient temperature. Data shown represents\n steady-state testing at 20\u00b0C ambient.\n \n 21700 Case Study\n

\n Temperature control under real charge and discharge\n <\/h3>\n \n A Panasonic NCR21700T cell was cycled under active SBTR temperature\n control at 20\u00b0C ambient to demonstrate performance during high-rate\n electrical loading.\n \n \n High-Rate Discharge\n -2C \/ -10 A\n With the TEC control point set to 20\u00b0C, the cell was discharged to\n 2.5 V while the opposite side of the cell increased by approximately 4\u00b0C.\n \n High-Rate Charge\n 3.6C \/ 18 A\n After the TEC setpoint reached 40\u00b0C, the cell was charged to 3.95 V.\n The opposite side of the cell increased by approximately 3\u00b0C during\n the high-rate charge.\n \n The result: temperature becomes part of the test – not an uncontrolled consequence of it.\n SBTR actively maintains the programmed thermal condition while the\n battery is being electrically stressed, enabling more repeatable\n electro-thermal characterization.\n \n A chamber controls the environment.
\n SBTR controls the cell.\n Independent cell-level thermal control lets researchers separate true\n electrochemical behavior from uncontrolled temperature variation –\n especially during fast charge, high-rate discharge, and aging studies.\n

\n\t\t\tApplications and Test Methods\t<\/h1>\n\t
