Abstract
A battery cluster and an energy storage system are provided. The battery cluster includes multiple battery modules, all of the multiple battery modules are arranged in even rows, and each battery module is connected in series with an adjacent battery module one by one, to form a ring connection. Such that the length of a cable connecting a positive electrode and a negative electrode of a battery cluster to a switch box is less than a preset value. In the present disclosure, each battery module in the battery cluster is connected in series with an adjacent battery module one by one, such that a ring connection is formed, thereby reducing the cost of connecting cables and the total cost of the energy storage system.
