Power transmission apparatus

A battery inspection apparatus includes a temperature control system configured to provide a temperature control of the batteries by supplying a temperature control fluid through a battery supporting portion to flow, between adjacent batteries, the fluid along the side surfaces thereof and by discharging the fluid through a contactor supporting portion. The contactor supporting portion is provided to face the battery supporting portion and supports a plurality of contactors. The temperature control system may include at least one cross-flow fan that is arranged along an array direction of the batteries, a vent of the fan directed to the plurality of batteries, in order to supply an air flow toward the plurality of batteries.
