A secondary flow passage is defined between the secondary surfaces and the wall surface of the case that faces the secondary surfaces. One of the primary flow passage and the secondary flow passage functions as a supply passage that supplies a heat medium to the inter-cell flow passage. The other one of the primary flow passage and the secondary flow passage functions as a discharge passage to which the heat medium is discharged from the inter-cell flow passage. | 02-05-2015 |
20150111075 | BATTERY CELL ASSEMBLY - A battery cell assembly having a first battery cell and a cooling fin is provided. The first battery cell has a first housing and first and second electrical terminals. The cooling fin is disposed against the first housing. The cooling fin has a substantially rectangular-shaped plate that extends along a longitudinal axis. The substantially rectangular-shaped plate has a plate portion with a first side and a second side. The first side has a first plurality of recessed regions and a first plurality of flat regions. Each recessed region of the first plurality of recessed regions is disposed between two flat regions of the first plurality of flat regions along the longitudinal axis. The first housing of the first battery cell is disposed against the first side such that the first housing contacts the first plurality of flat regions. | 04-23-2015 |
20150357624 | ENERGY STORAGE DEVICE AND METHOD OF MANUFACTURING ENERGY STORAGE DEVICE - An energy storage device includes: a first guide portion which is arranged in the inside of a case and allows an electrolyte solution to flow toward one end of an electrode assembly in a winding axis direction from an electrolyte solution pouring hole; and a second guide portion which is arranged in the inside of the case and allows a fluid to flow toward the electrolyte solution pouring hole from the inside of the case, and which prevents the electrolyte solution from flowing toward the other end of the electrode assembly in the winding axis direction from the electrolyte solution pouring hole or suppresses the electrolyte solution from flowing toward the other end of the electrode assembly in the winding axis direction from the electrolyte solution pouring hole. | 12-10-2015 |
20160006014 | BATTERY PACK - The present invention relates to a battery pack including a housing, a latch mechanism, a printed circuit board connected to electrical terminals, and an internal frame. The housing includes a first and second portion. The first portion includes openings that receive the latch mechanism and openings that receive the terminals. The battery pack also includes a latch cover that protects against water infiltrating between the openings and the latch mechanism, and a terminal cover that protects against water infiltrating between the first housing portion and the terminals. Water that enters the battery pack is directed to the bottom of the battery pack. The water is then drained through openings in the lower housing portion. The internal frame includes openings that secure batteries within the lower housing portion with the help of wedges that are positioned in between adjacent rows of batteries. | 01-07-2016 |

20160079633 | SYSTEMS AND METHODS FOR BATTERY SYSTEM TEMPERATURE ESTIMATION - System and methods for estimating a temperature of a battery are presented. In some embodiments, a method of estimating a temperature of a battery system may utilize measured battery system temperature data and measured ambient temperature data. Based on the measured temperature data, an average estimated temperature of the battery system may be determined using, at least in part, an extended Kalman filter and an energy balance process model associated with the battery system. | 03-17-2016 |
20160111762 | ELECTRICAL STORAGE APPARATUS - An electrical storage apparatus of the invention has a first and a second electrical storage module arranged in a first direction. Each of the electrical storage modules has a plurality of cylindrical electrical storage elements, a support plate and a casing. The support plate supports a portion of each of the electrical storage elements. The casing surrounds the plurality of electrical storage elements and the support plate to form a space in which air moves. The casing has an air intake opening for moving air from a passage into the space and an air discharge opening for moving the air in the space out of the casing. The passage for moving the air in a second direction orthogonal to the first direction is formed between the first and second storage modules, and the air is used for regulating temperature of each of the electrical storage modules. | 04-21-2016 |
20160126604 | POWER STORAGE APPARATUS - A power storage apparatus includes a plurality of spacers. The plurality of spacers is alternately stacked with the power storage devices. Each of the spacers defines a space through which cooling air flows. The spacers include first spacer and second spacer. The first spacer is a spacer disposed between the end plate and one of the plural power storage devices that is located adjacent to the end plate. The first spacer includes guide member. The guide member is arranged in a circumference of the opening of at least one of the inflow port and the outflow port so as to narrow the opening. | 05-05-2016 |
