Lithium battery pack current-limiting equalization grouping method

The invention relates to the technical field of lithium batteries, and discloses a lithium battery pack current-limiting equalization grouping method, which comprises the following steps of: firstly assembling a lithium battery pack, then charging the battery by installing a charging device, and controlling the charging during charging. In the invention, when the lithium batteries are assembled, a high-capacity lithium battery pack with the same series number is connected in parallel to the battery pack, and each single battery in the high-capacity lithium battery pack is independently charged during charging, so that the voltages of all the single batteries are equal after being fully charged, and the single batteries are always kept in an equilibrium state; and current control is carried out when the lithium battery pack is charged through various methods, so that the lithium battery pack is always in a balanced state during charging or discharging, and the situation that the service life of the battery is
