Abstract

The invention relates to a thermal battery test system, in particular to a thermal battery excitation, discharging and simulation real on-load situation, and aims to realize functions of a virtual digital oscilloscope and a recorder and record complete waveforms of parameters such as test voltage, test current, test temperature and the like which are changed along with the time in real time. The thermal battery test system comprises a thermal battery, a central control circuit, a high-power load circuit, a signal acquisition circuit, a data storage circuit, a data processing circuit system, a security circuit and a main display module. A test instruction is sent through a human-machine interface of computer application software; the central control circuit is started to simulate a load of a product electrification system on the thermal battery; meanwhile, and the signal acquisition circuit is started to acquire output voltage, output current and work time of the thermal battery and display the output voltage, the output current and the work time on a simulated oscilloscope of the application software. The thermal battery test system is high in integration degree, so that the accuracy, the reliability, the stability and the checking and acceptance efficiency for checking and accepting the thermal battery when the thermal battery is put into a factory are improved.

Description

technical field [0001] The present invention relates to a thermal battery test system, in particular to a thermal battery activation, discharge, simulation of real loading conditions, the realization of virtual digital oscilloscope and recorder functions, real-time recording of parameters such as test voltage, current and temperature change with time complete A waveform belongs to the field of electronic detection. Background technique [0002] Thermal batteries are used as power supply devices for electronic instruments, and their product performance is related to the stability and reliability of the system. Before assembly, thermal batteries must be sampled and tested in batches to ensure that the performance indicators of this batch of products meet the technical requirements. [0003] Thermal batteries have the advantages of short activation time, high output current density, high specific power, long storage life, and wide operating environment temperature range. At th...
