Embodiment Construction

[0014] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] figure 1 Shown is the lead-acid battery for the electric bicycle of the present invention, including a battery tank 1 and several pole groups 2, the battery tank 1 is provided with a baffle plate 11 to divide the battery tank into six side-by-side battery cells 12, as figure 2 As shown, each electrode group is placed in a battery cell. A single pole group includes 4 positive plates and 5 negative plates stacked alternately. The aspect ratios of the positive and negative plates are both 1.2. The thickness of the positive and negative plates is 1.5-2.3 mm, which is beneficial to increase the surface area of ​​the electrochemical reaction of the plates, enhance the high-current discharge capacity of the battery, effectively improve the charge acceptance performance, and increase the utilization rate of positive and negative active mat...

Abstract

The invention discloses a lead-acid battery for an electric moped. The lead-acid battery comprises a battery case and multiple pole units. Baffle plates are arranged in the battery case and divide the battery case into multiple side-by-side battery single cells. Each one of the multiple pole units is arranged in corresponding one of the multiple side-by-side battery single cells. The lead-acid battery can effectively reduce a lead use amount of a grid and a lead use amount of a bus-bar and also greatly reduce a product cost.

Description

technical field [0001] The invention relates to a lead-acid storage battery for an electric power-assisted vehicle. Background technique [0002] With the development of the electric moped industry, as a new type of green transportation tool, it has broad market prospects and great environmental protection value. With the development of electric mopeds, the motor has reached 350W, 500W, and 800W from 180W in the past. It is also a huge challenge to the use conditions of the battery and the technical improvement of the battery. [0003] With the development of the electric bicycle battery industry for more than 10 years, the technology is also approaching maturity, more and more battery manufacturers are entering this industry, and price competition is becoming more and more exciting. Factors such as the increase in wage costs and the enhancement of environmental protection awareness have led to a sharp increase in product costs and increasingly fierce market competition. Co...
