Abstract
The utility model relates to a lead acid battery and electric motor car, include the battery case, install utmost point crowd in the battery case, the battery case has long wide height, the height dimension of battery case is greater than length dimension, length dimension is greater than width dimension, gravity direction when lead acid battery places with the width direction of battery case is unanimous. The utility model discloses a lead acid battery placing means is favorable to riding the layering of stable, reduction electrolyte, can practice thrift the space in the non-gravity side on the electric motor car again.
Description
Technical Field
The utility model relates to a battery field.
Background
At present lead acid battery, when using, the polar plate becomes vertical placing in lead acid battery case, the direction of gravity direction unanimous also be exactly the direction of battery case height of polar plate length direction and battery promptly, the external wiring terminal is located the top of polar plate, such using-way, polar plate length size is big, electrolyte easily produces the layering phenomenon, the such placing-way of on the other hand, because the battery case height is higher, the focus of battery is higher, install back on the electric motor car, lead to the electric motor car key to uprise, be unfavorable for the stability of riding, nobody has proposed the solution that does benefit to the stable battery installation of riding at present yet.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a lead-acid storage battery, include the battery case, install utmost point crowd in the battery case, the battery case has long wide height, the height dimension of battery case is greater than length dimension, length dimension is greater than 2 times of width dimension, utmost point crowd includes the polar plate, the polar plate has long wide thick, the length dimension of polar plate is greater than width dimension, width dimension is greater than thickness dimension, the length direction of polar plate is unanimous with the length direction of battery case, the width direction of polar plate with the width direction of battery case is unanimous, the thickness direction of polar plate with the height direction of battery case is unanimous, its characterized in that, the direction of gravity when lead-acid storage battery placed with the width direction of battery case is unanimous.
Further, still include the cladding baffle on the polar plate, the length direction of polar plate is the side of polar plate, its characterized in that, the cladding of baffle is in the side of polar plate.
The utility model discloses still protect an electric motor car.
The utility model discloses a lead acid battery's mounting means is favorable to riding of electric motor car stable, also is favorable to reducing battery electrolyte layering phenomenon in addition, prolongs battery life.

Detailed Description
The invention will be further described with reference to specific embodiments.
As shown in fig. 1, the utility model discloses storage battery, including battery case 1, battery cover 2, polar plate 3 includes length width thick, and when battery case 1 had length width height and placed, the length width height direction of battery case 1 was unanimous with the length width thickness direction of polar plate 3, was respectively along X, Y, Z directions. The lead-acid storage battery shown in fig. 1 is placed on the electric vehicle in such a way that the gravity direction of the battery is consistent with the width Y direction of the battery case 1, so that the gravity center of the whole electric vehicle can be effectively reduced, and the riding stability of the electric vehicle is facilitated. Further, if the electric vehicle is not long enough, the batteries may be stacked up and down, even such a 2-fold battery case width dimension is a dimension lower than the length of the battery case 1. The aim of lowering the center of gravity can still be achieved.
As shown in fig. 2, the lead-acid storage battery is placed in the current battery placing mode, the gravity direction of the battery is consistent with the length direction X of the battery case 1, and the traditional placing mode mainly considers that the wiring is convenient, but the gravity center is higher, and the electrolyte layering phenomenon is serious.
As shown in fig. 3 and 4, the positive and negative electrode plates are separated by the separator 4, the electrode plate 3 has side edges 3a, i.e., edges in the longitudinal direction, and the separator 4 is wrapped in the direction of the side edges 3 a. The placing mode shown in figure 1 can vibrate in the riding process of the electric vehicle, so that the side edge 3a of the polar plate can vibrate up and down in the battery shell, the side edge cladding is carried out by changing the traditional upper and lower wrapping sheet form, and the damage to the polar plate caused by the vibration of the side edge of the polar plate can be effectively reduced. In addition, the side direction is coated, and the width direction of the polar plate 3 is consistent with the gravity direction, so that the acid absorption (acid climbing) height of the partition plate is shortened, and the influence of acid stratification is obviously relieved.
As shown in FIG. 5, the lead-acid storage battery of the present invention is stacked on the electric vehicle 5.
The utility model discloses a lead acid battery's placing means is favorable to riding the layering of stable, reduction electrolyte, can practice thrift the space in the non-gravity side on the electric motor car again.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the scope of the claims.
