Abstract

The invention discloses a battery system with a hybrid cooling device, which comprises a battery charger assembly, a battery assembly, a discharge switch assembly, an air cooling assembly and a watercooling assembly, wherein the battery charger assembly comprises N chargers; the battery assembly comprises N battery modules; the discharge switch assembly comprises N discharge switch slave assemblies and a discharge switch main assembly; the air cooling assembly comprises two first fans and a plurality of second fans; the N battery modules are arranged in two columns, and the two first fans arerespectively arranged on the two ends of a cooling air duct formed via a middle space of the two columns of storage modules; the battery module is formed by stacking the M battery submodules; and a plurality of second fans are arranged on the end surface of one side of the battery submodules opposite to the cooling air duct. The battery system with a hybrid cooling device in the invention can cool the battery system efficiently and quickly, thereby realizing warning of a cooling failure, safety isolation of high and low voltages and high system integration, and improving the safety applicability of the whole system.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and more specifically relates to an accumulator system with a hybrid cooling device. Background technique [0002] The energy supply system for shipboard electromagnetic launch needs to have high energy density and high power density at the same time. Its battery system is composed of tens of thousands of single cells connected in series and parallel. will generate a lot of heat. The length of battery charging and discharging time interval determines the emission efficiency of electromagnetic emission. Therefore, it is necessary to maximize the use efficiency of the device within the safe tolerance range of the device. Therefore, the charging and discharging time period of the battery is required to be short, and the pulse cycle discharge method is adopted. At this time, both the battery and the discharge switching device are in the limit application state, and an efficient and targeted coo...
