The invention discloses an electric vehicle storage battery combining mode which specifically comprises the following steps: (1) forming a 14-40V battery pack by using a plurality of small batteries; (2) serially connecting a plurality of battery packs so as to form a single string of storage batteries of which the total voltage is that of an overall electric vehicle storage battery pack; and (3) connecting a plurality of batteries in parallel and in series so as to form an overall electric vehicle storage battery pack. The invention further discloses an electric vehicle storage battery pack maintaining mode which mainly comprises the following steps: detecting the current value of each battery string when a battery pack works, and when the difference exceeds process standard, performing maintenance operation. According to the method, the damage number of storage batteries can be greatly reduced, and the operation cost can be lowered.
