Abstract: A battery pack includes a battery group including battery rows consecutively disposed adjacent to each other, with the battery rows including secondary batteries disposed parallel to each other and spaced apart from each other, a frame for surrounding the battery group, and a plurality of first ribs that are each disposed between adjacent battery rows. The first ribs include supporting grooves that are formed in lateral surfaces of the first ribs and accommodate portions of edges of the secondary batteries, and ends of each of the first ribs are coupled to the frame.

Abstract: An energy storage apparatus and a rack housing assembly having the same are disclosed. In one embodiment, the energy storage apparatus includes i) a plurality of battery trays arranged substantially parallel to each other so as to form at least one row and ii) a first duct located at a first side of the battery trays, wherein a plurality of first openings are formed in the first duct. The apparatus may further include i) a second duct located at a second side of the battery trays, wherein a plurality of second openings are formed in the second duct, and wherein the first and second sides are different from each other, ii) an air intake configured to forcibly intake air into the first duct and iii) an air exhaust configured to forcibly exhaust air from the second duct to the outside of the energy storage apparatus.

Abstract: A battery pack comprises a battery module disposed inside a case, the battery module including a plurality of battery units, each including first and second lead tabs which protrude outside of each battery unit and which have bent portions. An insulation plate includes a plurality of ribs, wherein the bent portions of the lead tabs extend over the ribs, and a plurality of bus bars are disposed over the lead tabs and electrically connect the battery units serially with each other, the bus bars being fixed to the ribs.

Abstract: A secondary battery includes a battery unit, a thermistor for detecting a temperature of the battery unit, and a frame case for supporting the battery unit and the thermistor together, and including a thermistor accommodator having a concave shape and accommodating the thermistor. Accordingly, a way of installing the thermistor is improved.

Abstract: A secondary battery and a secondary battery module. The secondary battery includes: a battery unit; and a frame case that supports the battery unit and has a first side portion and a second side portion which are opposite to each other and on which first and second spacers are respectively formed, wherein the first and second spacers have asymmetric dimensions. Accordingly, the secondary battery and the secondary battery module include a misassembly-preventing mechanism.
