Electric power storage device for powering electric drive motor of electric motor vehicle, has rigid structure for defining circulation circuits to circulate fluid to cool storage module sets, where modules have independent cooling circuits

摘要

The device (10) has two sets of electric power storage modules (19, 20) supported by a rigid structure (11), where the modules have independent cooling circuits. The structure has a tubular central section (14), longerons (15, 16) and crossbars (17, 18) for channeling a cooling fluid of the modules. The structure defines circulation circuits for circulating the cooling fluid to cool the sets of electric power storage modules. The central section, longerons and crossbars are made of aluminum alloy.
