When it is determined that the battery has positive polarity, control is performed so as to close between the charging device 3 and the charging contacts 41 and 42, so that the connection between the battery 2 and the battery charging terminals 21 and 22 in the battery car 1 is performed. When the connection is the reverse of the normal connection, a closed circuit is not formed between the battery 2 and the charging device 3, and the battery 2 can be prevented from being short-circuited,
There is no danger of explosion or fire, and safety can be maintained. [2] The charging device described in the embodiment is the device according to the above [1], and an alarm is issued when the determination unit (DT1) determines that the polarity of the battery 2 is the opposite polarity. With means to emit.
