Abstract
The invention discloses a lead-acid accumulator comprising an battery box which is composed of a battery jar with a battery jar opening and a battery jar cover; the length, the width and the height of the cell box are respectively 150-152mm, 98-100mm and 98-100mm; the battery jar opening just is opposite to the outer wall surface of the side with minimum area on the cell box; the battery jar is provided with 5 spacers which are parallel to each other; the spacer divides the battery jar into 6 cell chambers; each cell chamber is provided with a polar group composed of polar plates and clapboards, wherein, the width of the polar plate is 65-95mm, and the length is 100-130mm. At the condition of not changing the appearance size of the accumulator, by adopting large-sized polar plates, the sectional area and the surface area of a grid are increased by 20%, the specific surface of an active substance are increased, the current density of the polar plate is reduced and the current distribution is more uniform.
Description
Technical field
The present invention relates to a kind of storage battery, relate in particular to a kind of lead acid accumulator.
Background technology
The develop rapidly that the each technological innovation of lead acid accumulator brings industry, electric boosted automobile-used lead acid accumulator are develop rapidlys after experience technological innovation for the second time, and what its use amount was maximum is 6-DZM-10, two kinds of size battery of 6-DZM-12.Traditional mentality of designing is to have selected the 12V12Ah battery case for use according to compacted accumulator technical standard at that time, designs battery of electric vehicle pole plate, utmost point crowd etc. then and produces battery of electric vehicle.Just forming industry standard after operation a period of time on the market.Draw through the checking of market for many years: 6-DZM-10,6-DZM-12 battery biggest quality problem are to have in the whole Battery pack that singly only fall behind phenomenon, mileages of continuation is short, useful life is long etc.Different manufacturers the shared ratio of various quality problems occurs and have certain difference.In brief, there is tangible technological deficiency in popular two kinds of size battery of electric motor car 6-DZM-10,6-DZM-12 on the present market.
Existing battery size is long to be 151mm, and wide is 99mm, and two kinds of size battery height are variant slightly; Pole plate is small pieces production, is coated with cream again through die casting and processes, and pole plate all is 9 disposable in flakes productions; The quantity of polar plate that single is produced is more; Efficient is high, but the consistency of pole plate is difficult to control, increases the control difficulty of the consistency of performance of battery.Battery case is 2 * 3 structure, and the battery assembling is tighter, does not also have what gap between pole plate and the battery case, causes on 6-DZM-10 and 6-DZM-12 battery, adding colloidal electrolyte and is difficult to realize.
Existing 6-DZM-10,6-DZM-12 battery of electric vehicle adopt 12V, the 12Ah battery case of compacted accumulator standard.Because the restriction of battery case, the general height of the size of battery pole plates is 68-74mm, and wide is 38-44mm.This pole plate size has caused the current density of pole plate excessive, and CURRENT DISTRIBUTION is inhomogeneous.Simultaneously, there is certain problem in both positive and negative polarity active material ratio, and the acid amount has not enough possibility under the design of lean solution formula.Thereby the specific energy that causes battery not high (about 35Wh/Kg), cycle life is below 500 times.
Summary of the invention
The invention provides a kind of lead acid accumulator, under the prerequisite that does not change battery overall dimension, change the pole plate size, solved that existing polar plate of lead acid storage battery current density is excessive, the uneven problem of CURRENT DISTRIBUTION.
A kind of lead acid accumulator; Comprise the battery case of forming by the battery case and the groove lid of trough of belt mouth; The length of battery case is respectively 150～152mm, 98～100mm, 98～100mm, and described notch is the minimum side outside wall surface of area on the battery case, is provided with 5 partitions that are parallel to each other in the said battery case; Partition is separated into 6 groove chambers with the battery case inner chamber; Described each groove is indoor to be equipped with the utmost point crowd who is made up of pole plate and dividing plate, and the width of pole plate is 65～95mm, and length is 100～130mm.
The ratio of described pole plate length and width is 1.2～1.4.
Said groove lid comprises the top board of capping notch and the shirt rim that cooperates with the notch edge, and the outer wall of shirt rim is provided with splicing ear.Described splicing ear is arranged on the maximum outside wall surface of battery case area.
Each utmost point crowd positive plate of said battery is that 2～4, negative plate are 2～4.But not the utmost point of conventional electric-powered car battery is mined massively with 7 positive plates, 8 negative plates.Described utmost point crowd thickness is 10～15mm.
Storage battery of the present invention adopts the large scale pole plate under the condition that does not change battery overall dimension, the specific surface of the sectional area of increase grid and surface area 20%, increase active material makes plate current density to reduce, and CURRENT DISTRIBUTION can be more even.
The pole plate of lead acid accumulator of the present invention is bigger than the area of traditional pole plate, makes pole plate and becomes 4 in flakes in flakes by 9, and the quantity of once producing pole plate reduces, and has improved the consistency of pole plate, thereby has improved the lead acid accumulator consistency of performance.
The utmost point crowd of lead acid accumulator of the present invention and the gap of groove chamber increase, and colloidal electrolyte can add inside battery smoothly, has avoided insufficient electrolyte.
