Definitions

  • the battery pack according to the present invention has an overall capacity compared to a battery pack composed only of secondary batteries belonging to the first battery group.
  • the overall capacity can be increased as compared with a battery pack composed only of secondary batteries belonging to the second battery group.
  • the secondary battery belonging to the second battery group included in the battery pack of the present invention belongs to the first battery group because the average operating voltage of the power generating element body is higher than the secondary battery belonging to the first battery group. Compared with a battery pack composed only of secondary batteries, voltage drop at the initial stage of discharge can be suppressed.
  • Example 1 generates less heat at the time of high output as described above.
  • Example 4 Temperature measurement during high current discharge for Example 1 and Example 2 Regarding the battery pack according to Example 1 shown in FIG. 2A and Example 2 shown in FIG. Similarly, changes in battery temperature were measured while charging and discharging.
  • the temperature rise at the time of high output can be reduced by making the battery group A unevenly distributed in the central region of the block-shaped battery group.
  • the reason for this is that when there is not much difference between the currents flowing through battery A and battery B, the amount of heat generated by battery A is smaller than that of battery B.
  • the whole battery pack can be soaked in such a way as to absorb the heat generated by the battery B having a large heat generation amount on both sides.
  • the battery A is disposed at the end of the battery pack, the heat generated from the battery B cannot be sufficiently absorbed by the battery A, and the overall temperature of the battery pack cannot be equalized. The overall temperature is thought to rise.

Abstract

La présente invention concerne des blocs de batteries (1, 2) permettant d'obtenir une capacité élevée et une caractéristique de sortie élevée dans un bloc de batteries comportant de multiples batteries secondaires connectées en parallèle. Ces blocs de batteries (1, 2) sont formés en connectant des circuits de protection (30) et des connecteurs (31) à des faisceaux de batteries. Ces derniers sont formés en alignant un groupe de batteries (10) comportant de multiples (trois) batteries (A) connectées en série et un groupe de batteries (20) comportant de multiples (trois) batteries (B) connectées en série, et en connectant ces groupes de batteries en parallèle. Les batteries (A) et les batteries (B) sont des batteries au lithium-ion, et ont la même taille, mais la tension de fonctionnement moyenne de l'élément générateur de puissance est réglée à un niveau plus élevé et la résistance interne est réglée à un niveau plus bas pour les batteries (A) que pour les batteries (B).
