摘要： The present invention relates to a cooling structure of a lithium ion secondary battery system. The cooling structure of a lithium ion secondary battery system according to the present invention provides cooling channels for lithium battery unit cells accommodated by a laterally partitioned arrangement of main frames, each having a heat radiation part and lattice-shaped paths, and partitioning frames, and allows air, blown by a cooling fan, to cool the lithium battery unit cells while passing through the cooling channels and the lattice-shaped paths. Each of the main frames has a pair of passage slots formed in both sides thereof to allow the air blown by the cooling fan to be directly blown to each accommodated lithium battery unit cell, thus forming each secondary cooling channel communicating with the pair of passage slots.

摘要： The present invention relates to an apparatus and method for testing batteries, which can prevent errors from occurring due to the tolerance of voltage sensors when the charged states of batteries are measured, and can charge a battery having a charged state deteriorated due to the difference in the resistance of each battery. The apparatus includes a voltage circuit for measuring voltages of N batteries. A resistance circuit decreases voltages of batteries, which are greater than a reference voltage. A connection switch unit selects any one of the N batteries. A divert change unit separates polarities of each battery and changes positions of an cathode and a anode of the battery depending on separated polarities. A selection switch unit selectively connects the cathode and anode of the battery to an cathode and a anode of the voltage circuit or the resistance circuit.
