Abstract
The invention relates to a method for replacing a single battery in a battery pack of an electromobile. The method comprises the following steps of: enabling the cathode of the single battery required to be replaced to face upwards; scissoring cathode ends of all single batteries in a battery module from soldering points; expanding installation holes of a plastic cathode plate in which the single battery required to be replaced is located; scissoring anode ends of the all single batteries in the battery module from soldering points; pushing off the anode end of the single battery required to be replaced towards the cathode end; making the anode of a new single battery faced downwards; pushing the new single battery into a plastic anode plate; respectively soldering the anodes and the cathodes of the new single battery and other same-group single batteries on an anode aluminum plate and a cathode aluminum plate; and placing the battery module in the battery pack. According to the method, out-of-work single batteries can be independently replaced when some or more single batteries in the battery module are out of work, other single batteries in normal operation do not need to be replaced, so that the cost is saved, and the service life of the battery module is prolonged. Moreover, the method is simple in operation and convenient to replace.
