Battery Heater Board for precise temperatures during tests

HardwareX, vol. 22, pp. e00655

Abstract

The Battery Heater Board is an open-source hardware designed for precise temperature control during battery testing. This device integrates the heater, driver, and temperature sensors on a single metal core printed circuit board, allowing for accurate and compact temperature control. The board uses a synchronous buck converter to drive a custom layout heating trace integrated into the metal core printed circuit board. The included script for meandering a trace used as a heating foil helps to adapt to other applications or formats. In addition, the metal core printed circuit board provides both precise temperature control and a smooth surface, which is critical for accurate battery testing. This paper describes the heater's design, components, and assembly and presents validation results demonstrating the device's effectiveness in setting stable temperatures. The Battery Heater Board is an open-access, cost-effective solution for battery researchers and engineers requiring reproducible and precise temperature conditions.
