Abstract
Methods, systems, and apparatuses to house cooling fluid for a battery are presented which include a main reservoir configured to house battery cooling fluid, the main reservoir including an overflow opening; and a flexible overflow reservoir coupled to the overflow opening and configured to (1) flexibly expand in volume during inflow of excess battery cooling fluid from the main reservoir through the overflow opening and (2) flexibly contract in volume during outflow of excess battery cooling fluid to the main reservoir through the overflow opening; the flexible overflow reservoir further configured to maintain a substantially same internal pressure during an expanded state or a contracted state of the flexible overflow reservoir.
Claims20
An apparatus, comprising:
- a main reservoir configured to house battery cooling fluid, the main reservoir including an overflow opening;
- and
- a flexible overflow reservoir coupled to the overflow opening and configured to (1) flexibly expand in volume during inflow of excess battery cooling fluid from the main reservoir through the overflow opening and (2) flexibly contract in volume during outflow of excess battery cooling fluid to the main reservoir through the overflow opening;
- the flexible overflow reservoir further configured to maintain a substantially same internal pressure during an expanded state or a contracted state of the flexible overflow reservoir.
An apparatus, comprising:
- a first means for housing battery cooling fluid, the first means including an overflow opening;
- and
- a second means for housing overflow battery cooling fluid, the second means coupled to the overflow opening, the second means including (1) means for flexibly expanding in volume during inflow of excess battery cooling fluid from the first means through the overflow opening and (2) means for flexibly contracting in volume during outflow of excess battery cooling fluid to the first means through the overflow opening and (3) means for maintaining a substantially same internal pressure during an expanded state or a contracted state of the second means.
A method comprising:
- housing battery cooling fluid in a main reservoir, the main reservoir including an overflow opening;
- housing overflow battery cooling fluid of the main reservoir in a flexible overflow reservoir coupled to the overflow opening and configured to (1) flexibly expand in volume during inflow of excess battery cooling fluid from the main reservoir through the overflow opening and (2) flexibly contract in volume during outflow of excess battery cooling fluid to the main reservoir through the overflow opening;
- and
- maintaining a substantially same internal pressure at the flexible overflow reservoir during an expanded state or a contracted state of the flexible overflow reservoir.
