Problems solved by technology

The structure of the beam needs to be adjusted, which interferes with the strength; if the battery is placed on the side, the plate is placed in a similar way as a cantilever beam, and it will affect the quality assurance of the battery when used in a bumpy environment
In addition, the available space between the girders is limited, and other spaces such as the door cavity, the lower part of the seat, and the lower part of the vehicle floor are not available, and some passenger space needs to be occupied

Embodiment Construction

[0011] Referring to the accompanying drawings, there are three pole groups 2 inside the housing 1, and the three pole groups are arranged in a flat shape. The sides of the plates in adjacent pole groups are close to each other. The thickness B of the housing is 9cm, which is obviously smaller than that of the housing. length and height. Three pole groups are connected in series to form a 6V150Ah battery. The non-serial poles of the pole groups at both ends protrude out of the casing to form positive and negative output terminals 3, which are located at both ends of the top of the battery, and three safety valves 4 are located on the top of the battery. All the pole plates in the pole group are parallel and stacked along the thickness direction of the casing.

Abstract

The invention discloses a valve-controlled power lead-acid storage battery of a flat structure. In the valve-controlled power lead-acid storage battery, a plurality of pole groups are arrayed in a flat manner, side edges of polar plates in adjacent pole groups are close, and the thickness of a shell is obviously smaller than the length and the height of the shell and is smaller than 10cm. The valve-controlled power lead-acid storage battery is used as a vehicle power battery, can be flatly arranged at the lower part of a vehicle bottom plate or among cross beams with sufficient space due to much reduced thickness, and is convenient to arranged and maintain; in addition, because the valve-controlled power lead-acid storage battery is used flatly, the height of electrolyte is lowered and the polar plate is placed flatly, so that the stratification of the electrolyte is alleviated and oxygen recombination can be improved, and thus, the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to a valve-controlled power lead-acid storage battery with a flat structure, which is used as a vehicle power supply. Background technique [0002] The batteries currently used as vehicle power include lithium batteries, nickel metal hydride batteries, combustion batteries, lead-acid batteries, etc. Due to its small specific energy and high price, nickel-metal hydride is currently used in the field of hybrid vehicles; due to the high price, short life of key materials, and technical problems affecting the overall life of fuel cells, the application of fuel cells in the field of vehicles is still in the conceptual stage. ; Lithium batteries are used in the field of vehicle power, but safety issues and price issues seriously affect its market share. [0003] Lead-acid battery occupies a pivotal position in the field of secondary batteries by virtue of its excellent performance-price ratio. Lead-acid batteries have high working vol...
