The present invention relates to an energy storage module system and, more specifically, to a hybrid energy storage module system which uses a lithium battery and a lead storage battery selectively according to wattage required in a load, by mutual supplementation of the lithium battery and the lead storage battery. The hybrid energy storage module system according to the present invention supplies electricity required in driving the load, and includes an energy storage device, a first sensing unit, a second sensing unit and a controller. The energy storage device includes a plurality of lithium battery modules and a plurality of lead storage battery modules. Also, the energy storage device includes a switching network which is configured to connect the battery modules in a different arrangement mode. The energy storage device supplies electricity by being connected to both ends of the load. The switching network may includes a path which connects the lithium battery modules and the lead storage battery modules, and a plurality of switches installed on the path. The first sensing unit is configured to measure a temperature and a voltage of the lithium battery modules, and the second sensing unit is configured to measure a temperature and a voltage of the lead storage battery module. The controller controls the switching network in order to change the arrangement mode of the lithium battery modules and the lead storage battery modules.
