Abstract

The invention discloses a high-and-low-temperature test platform device for a solid-state battery. The high-and-low-temperature test platform device comprises a base and a closed platform supported onthe base, and is characterized in that a sliding seat is slidably installed on the base; a temperature control compressor and a controller terminal are installed on the upper side end of the base; anauxiliary electric heating device is disposed on an inner side wall of the closed platform; the output end of the temperature control compressor is connected with the inside of the closed platform; atest mechanism is installed on the sliding seat; a test mechanism includes a battery holding seat fixedly arranged inside the closed platform; a cover plate is correspondingly arranged above the battery holding seat; and temperature sensors, pressure sensors, and voltage collectors in contact with a battery to be measured are arranged on the battery holding seat and the inner side wall of the cover plate, and are all in signal connection with the controller terminal on the base.

Description

technical field [0001] The invention relates to the field of high and low temperature performance testing equipment for batteries, in particular to a high and low temperature test platform device for solid state batteries. Background technique [0002] A solid-state battery is a battery that uses solid electrodes and a solid electrolyte. Solid-state batteries are ideal batteries for electric vehicles due to their high power-to-weight ratio. [0003] The traditional liquid lithium battery is also vividly called "rocking chair battery" by scientists. The two ends of the rocking chair are the positive and negative poles of the battery, and the electrolyte (liquid) is in the middle. Lithium ions are like excellent athletes, running back and forth at both ends of the rocking chair. During the movement of lithium ions from the positive electrode to the negative electrode and then to the positive electrode, the charging and discharging process of the battery is completed. The pri...
