The present invention relates to a constant temperature maintenance lead acid battery enclosure using a phase change material, and more specifically, by installing a constant temperature structure (containing phase change material) having a 25 degree characteristic on the outer wall of the lead acid battery enclosure, when the temperature of the lead acid battery is high It relates to a constant temperature maintenance lead acid battery enclosure using a phase change material that absorbs heat and emits heat when the temperature of the lead acid battery is low to maintain 25 degrees at all times. Through the present invention, by installing a constant temperature structure (containing phase change material) having a 25-degree characteristic on the outer wall of the lead acid battery enclosure, absorbs heat when the temperature of the lead acid battery is high, and releases heat when the temperature of the lead acid battery is low It will always provide the effect of maintaining 25 degrees. In addition, by maintaining a constant temperature at all times, by providing an effect that can improve the performance and life of the lead-acid battery, and by providing an enclosure structure that can periodically replace the PCM package, it provides convenience of replacement and convenience of maintenance. Is done.
