Battery system and temperature controlling unit thereof

摘要

A battery system may include a plurality of unit batteries each having a panel shape and stacked in series. The system may also include a plurality of heat conduction plates each having a panel shape and inserted between the unit batteries such that a first part of each respective heat conduction plate is inserted between opposing faces of corresponding unit batteries, with upper and lower faces of each respective heat conduction plate being in contact with the opposing faces of the corresponding unit batteries, and a second part of each respective heat conduction plate is exposed to an outside of the stacked unit batteries. The system may further include at least one heat pipe thermally coupling the plurality of heat conduction plates by successively penetrating the exposed second parts of the heat conduction plates, with an end of the heat pipe being thermally coupled to a heat radiator after penetrating a last heat conduction plate.

1. A battery system, comprising:
a plurality of unit batteries each having a panel shape and stacked in series with opposing faces of adjacent unit batteries being next to each other; a plurality of heat conduction plates each having a panel shape and made of a conductive material, and inserted between the unit batteries in a manner such that a first part of each respective heat conduction plate is inserted between opposing faces of corresponding unit batteries, with upper and lower faces of each respective heat conduction plate being in contact with the opposing faces of the corresponding unit batteries, and a second part of each respective heat conduction plate is exposed to an outside of the stacked unit batteries; and at least one heat pipe thermally coupling the plurality of heat conduction plates by successively penetrating the exposed second parts of the heat conduction plates at the outside of the unit batteries, with an end of the heat pipe being thermally coupled to a heat radiator after penetrating a last heat conduction plate, wherein the plurality of heat conduction plates comprise a first set of plates and a second set of plates, the first and second sets of plates being separated from each other, in which inserted parts of the first set of plates are inserted into the unit batteries from a first side of the unit batteries, and inserted parts of the second set of plates are inserted into the unit batteries from a second side of the unit batteries, and the at least one heat pipe penetrates exposed parts of the first and second sets of plates, and wherein the first and second sets of heat conduction plates are inserted between the unit batteries at a same level so as to be arranged in a manner such that ends of the first and second sets of heat conduction plates face each other in an inserted status between the unit batteries, and a space exists between two adjacent plates of the first and second sets of heat conduction plates set at the same level.
