An electrical storage device, comprising:
- a battery assembly that is constituted by electrically connecting a plurality of battery cells with one another through a conductive member;
- a casing in which the battery assembly is housed;
- a control unit that is placed on an upper surface of the casing, and monitors a physical state of the plurality of battery cells;
- electric components that include a high-rate circuit and a low-rate circuit of the battery assembly;
- and
- a protection member that protects the electric components, wherein:
- an uppermost surface of the protection member and an uppermost surface of the control unit are arranged to be leveled with each other.
An electrical storage device, comprising:
- first and second battery blocks each including a battery assembly constituted by electrically connecting a plurality of battery cells with one another through a conductive member and a casing in which the battery assembly is housed, with the first and second battery blocks being juxtaposed to each other;
- and
- a control unit, placed astride on a center of upper surfaces of the casings of the first and second battery blocks, that monitors a physical state of the plurality of battery cells, wherein:
- each of the upper surfaces of the casings of the first and second battery blocks is provided with first and second female threads axisymmetrically with respect to a central axis of the casing at one end in a longitudinal direction of the casing and a third female thread eccentrically across a width of the casing from the central axis at an other end in the longitudinal direction of the casing;
- first stud is screwed to the second female thread at the first battery block, a second stud is screwed to the first female thread at the second battery block, and third studs are screwed to the third female threads at the first and second battery blocks;
- the control unit is provided with a first mounting section, a second mounting section, and third mounting sections through which the first stud, the second, and the third studs pass, respectively;
- the first stud of the first battery block passes through the first mounting section and is screwed with a nut, the second stud of the second battery block passes through the second mounting section and is screwed with a nut, and the third studs of the first and second battery blocks pass through the third mounting sections and are screwed with nuts;
- and
- the first mounting section and the second mounting section are disposed at symmetrical positions across a boundary between the first and second battery blocks, and the third mounting sections are disposed at asymmetrical positions across the boundary between the first and second battery blocks.
