Abstract: A method for checking a wire connection comprises providing a first current by a first power channel and measuring a first voltage by a first measuring channel when each of a positive terminal of the first measuring channel and a positive terminal of the first power channel is connected to one of positive terminals of batteries and each of a negative terminal of the first measuring channel and a negative terminal of the second measuring channel is connected to one of negative terminals of the batteries after measuring the first voltage, providing a second current by the first power channel and measuring a second voltage by the first measuring channel, and determining whether the first measuring channel and the first power channel are connected to a same battery of the batteries.
