<p>PROBLEM TO BE SOLVED: To provide a method of improving the precision of determinations on whether there is a fine short circuit and whether there is a latent defect which may cause the fine short circuit for a method of inspecting an all-solid battery.SOLUTION: There is provided a method of inspecting an all-solid battery, the method including the steps of: (i) finding a voltage drop amountΔV1 due to a self-discharge of the battery after charging the battery; (ii) determining whether the voltage drop amountΔV1 exceeds a predetermined first reference value; (iii) charging the battery under pressure exceeding the restraint pressure in use of the battery, and then finding a voltage drop amountΔV2 due to a self-discharge by letting the battery discharge itself when the voltage drop amountΔV1 exceeds the predetermined first reference value; (iv) determining whether the voltage drop amountΔV2 exceeds a predetermined second reference value; and (v) determining the battery as a defective when the voltage drop amountΔV2 exceeds the predetermined second reference value.</p> |
