Abstract

A substrate includes a plurality of voltage-detection components, each of which includes (a) an upper connecting terminal that protrudes from one of a pair of first sides opposite each other of a body of a voltage-detection component and is connected to an adjacent voltage-detection component of an adjacent higher-ordered battery block of the battery pack, and (b) a lower connecting terminal that protrudes from the other of the pair of the first sides of the body and is connected to an adjacent voltage-detection component of an adjacent lower-ordered battery block of the battery pack. The plurality of voltage-detection components are aligned on the substrate in a direction substantially orthogonal to the pair of the first sides of the body of the component.

Claims

1. A voltage-detection component for each of battery blocks of a battery pack, configured to detect a voltage between both terminals of a unit cell that belongs to the battery block, the battery block including at least one of unit cells, the unit cells being connected in series with each other to constitute the battery pack, the unit cells being secondary cells, and the voltage-detection component comprising:

(a) a body having a pair of first sides opposite each other;

(b) a upper connecting terminal protruding from one of the first sides of the body and connected to a voltage-detection component of an adjacent higher-ordered battery block of the battery pack; and

(c) a lower connecting terminal protruding from an other of the first sides of the body and connected to a voltage-detection component of an adjacent lower-ordered battery block of the battery pack.

2. The voltage-detection component according to claim 1, further comprising:

(d) a cell-connecting terminal configured to connect the voltage-detection component to the connector to which voltages between both ends of the unit cells are input, the cell-connecting terminal protruding from one of a pair of second sides of the body opposite each other and between the pair of the first sides of the body; and

(e) a peripheral-component-connecting terminal configured to connect the voltage-detection component to a peripheral component, the peripheral-component-connecting terminal protruding from an other of the pair of the second sides of the body.

3. A substrate comprising a plurality of the voltage-detection components of claim 2, the voltage-detection components being aligned in a direction orthogonal to the pairs of the first sides of the bodies.

4. A substrate comprising a plurality of the voltage-detection components of claim 2, wherein the voltage-detection components are aligned in a direction orthogonal to the pairs of the first sides of the bodies, the connector being arranged adjacent to respective ones of the pairs of the second sides from which the cell-connecting terminal protrudes, and a plurality of the peripheral components being arranged adjacent to the respective others of the pairs of the second sides from which the peripheral-component-connecting terminal protrudes.
