Abstract
A lower battery module includes lower batteries and lower cooling air passages. An upper battery module is provided at an downstream of the lower battery module in a flow direction of the cooling air. The upper battery module includes upper batteries and upper cooling air passages. An intermediate duct is provided between the upper battery module and the lower battery module to prevent leakage of the cooling air. The intermediate duct includes a cutwater portion. The cutwater portion is provided along an inner circumference of the intermediate duct to cut a continuous flow of water from an inside of the upper battery module to an inside of the lower battery module.
Claims6
A battery unit comprising:
- a battery module formed of a plurality of batteries arranged in parallel, with cooling air passages interposed therebetween, wherein:
- said battery module includes an upper battery module and a lower battery module stacked in a flow direction of cooling air;
- an intermediate duct for preventing leakage of cooling air is arranged between said upper battery module and said lower battery module;
- and
- a cutwater portion for cutting a continuous flow of water from an inside of said upper battery module to an inside of said lower battery module is provided, along an inner circumference of said intermediate duct.
A battery unit comprising:
- a lower battery module comprising:
- lower batteries;
- and
- lower cooling air passages each of which is interposed between a first lower battery and a second lower battery adjacent to the first lower battery among the lower batteries;
- an upper battery module stacked on the lower battery module via a gap at an downstream of the lower battery module in a flow direction of the cooling air and comprising:
- upper batteries;
- and
- upper cooling air passages each of which is interposed between a first upper battery and a second upper battery adjacent to the first upper battery among the upper batteries;
- and
- an intermediate duct provided between the upper battery module and the lower battery module to prevent leakage of the cooling air and comprising:
- a cutwater portion provided along an inner circumference of the intermediate duct to cut a continuous flow of water from an inside of the upper battery module to an inside of the lower battery module.
