High-power lead storage battery

Abstract

The invention relates to a high-power lead storage battery, which comprises a bus bar assembly, a shell, a bottom cover, a transition cover, an upper cover, a middle cover, a plurality of accommodating cavities, single batteries and two series assemblies, wherein the bottom cover is arranged at the lower end of the shell; the transition cover and the upper cover are sequentially arranged at the upper end of the shell; the middle cover is located in the upper cover and connected with the upper end of the transition cover; the plurality of accommodating cavities are formed in the shell side by side left and right and penetrate through the upper end and the lower end of the shell; the number of the single batteries is the same as that of the accommodating cavities, and the single batteries are arranged in the accommodating cavities in a one-to-one correspondence mode; and the two series assemblies are arranged on the upper sides and the lower sides of the single batteries respectively. The high-power lead storage battery is high in power density, high in high-current charging and discharging capacity and short in charging time under the condition of the same boundary dimension.

Description

technical field [0001] The invention relates to the field of storage batteries, in particular to a high-power lead storage battery. Background technique [0002] Because of its stable and reliable, no memory effect, low price, and can be made into a single large-capacity battery, lead-acid batteries are widely used as car starting power, uninterruptible power supply, power supply and energy storage from electric bicycles to diesel submarines In the fields of power supply and other fields, its output and storage capacity still rank first in chemical power sources; at present, electric scooters in the city have become people's first choice, such as takeaway, express delivery, and logistics. With the use and dependence of electric vehicles, people also put forward higher requirements for the power of electric vehicles, such as shorter charging time and stronger horsepower. To solve such problems, it is necessary to increase the charging and discharging current, and the battery'...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of the current lead-acid storage battery with low power density, poor high-current charge and discharge capacity, and long charging time under the set external size, and provide a battery with the same external size and large power density. High-power lead-acid batteries with strong current charging and discharging capabilities and short charging time
