The present invention relates to a sealed storage battery having the same.

Power consumption tends to increase significantly. Also, improving fuel efficiency and reducing exhaust gas are major issues. Therefore, the power supply voltage was increased from the conventional 14V to 42V, and at the same time 36V
Introducing a simple hybrid system using batteries has been studied to solve fuel consumption and exhaust gas problems, and some have already put it to practical use.

Further, the external dimensions are considered to be the standard D size or B size (usually called in this way by the alphabet indicating the width × height division in the storage battery model display).

The inside of one battery case was divided into two parts at the center by partition walls, and each of the two divided chambers was separated by eight partition walls orthogonal to the center partition wall to divide the inside of the battery container into a field shape. A sealed lead acid battery using an 18-cell monoblock battery case is adopted.

Oxygen gas generated from the positive electrode at the end of charging is reacted with the negative electrode to reduce the amount of the electrolytic solution, thereby completely reducing maintenance. In addition, since the amount of the electrolytic solution is limited to a level such that a glass separator having a high liquid absorbing property is used and there is no free liquid, it is possible to make the position free. Therefore, it is becoming increasingly used for automobiles instead of the liquid lead acid battery. However, the reaction of consuming the oxygen gas generated in the positive electrode during charging in the negative electrode is accompanied by great heat generation. In addition, the heat capacity of the battery is small because the amount of electrolyte is reduced in order to smoothly consume oxygen gas. Therefore, there is a drawback that the battery temperature easily rises.

る。Further, in the D-size or B-size integrated battery, the conventional 6 cells are arranged in close contact with 18 cells in the 36V battery. Therefore, compared to the conventional
The temperature rises remarkably, and especially in the central part, the temperature rise becomes more remarkable than in the periphery. As a result, a temperature difference occurs between cells. Since the cells with high temperature and the cells with low temperature have different charging efficiency and gas absorption performance, the state of charge between cells is different, and an unbalanced state spreads during repeated charging and discharging. Then, the temperature of the cell in the central portion is remarkably increased and the cell is overcharged, which causes the entire battery to reach the end of its life.
