Abstract

The invention discloses an energy storage pack. The energy storage pack comprises a box body, wherein a box cover is arranged at the top of the box body, a plurality of battery modules are arranged in the box body and are connected in series, a box body front end surface is arranged at a front side of the box body, a negative output pole post and a positive output pole post of each battery module extend out of the box body front end surface, an air duct connection hole is formed in the box body front end surface, a fan is arranged in the air duct connection hole, a box body rear end surface is arranged at a rear side of the box body (1), an air inlet is formed in the box body rear end surface, an air duct is arranged at one side of the battery module, one end of the air duct is fixed at the box body rear end surface, and the other end of the air duct communicates with the air inlet. By arranging the air duct with a reasonable structure and matching a ventilation hole, the fan and the like, the energy storage pack has excellent heat dissipation performance, the problem of temperature difference among the battery modules is effectively solved, and the lifetime of the energy storage pack is prolonged.

Description

technical field [0001] The invention relates to an energy storage bag, in particular to an energy storage bag with good heat dissipation performance. Background technique [0002] With the decrease of petrochemical resources, environmental and energy crises are increasingly threatening the future survival of human beings. People's awareness of energy conservation and emission reduction has gradually increased, and they have begun to seek energy storage devices to recycle energy. Taking the rail transit energy storage package as an example, the energy storage link is added to the rail transit DC power supply system, which can absorb energy during regenerative braking, avoiding the rise of tunnel temperature and energy waste caused by resistance consumption; it can also provide energy during startup or acceleration. Partial power support reduces the fluctuation of the traction network. The emergence of this energy storage package meets the requirements of sustainable developm...
