Lead-acid start-stop battery with cooling cover

Abstract

The invention discloses a lead-acid start-stop battery with a cooling cover in the technical field of storage batteries. The lead-acid start-stop battery includes a heat dissipating casing body. A rotating shaft is arranged in the middle of the inner cavity of the heat dissipating casing body. The outer wall of the rotating shaft is in sleeve joint with a rotating sleeve. Blades are arranged on the outer wall of the rotating sleeve. A package projection is arranged on the top end face of the heat dissipating casing body. A heat dissipating cover plate is arranged on the top of the heat dissipating casing body. According to the device, the rotating shaft is inserted in the middle of the inner cavity of the heat dissipating casing body; the outer wall of the rotating shaft is connected withthe blades through the rotating sleeve; the ventilation in the casing body of the battery is strengthened by the rotation of the blades; the inner walls of two sides of the inner cavity of the heat dissipating casing body are provided with alternate ventilation holes, which effectively improves the ventilation and heat dissipation effect inside the heat dissipating casing body; a heat dissipatingmetal plate is arranged on the top of the heat dissipating cover plate, and the outer walls of two sides of the heat dissipating metal plate are provided with alternate heat dissipating holes; and theheat dissipating metal plate can improve the heat dissipation effect inside the heat dissipating casing body through the heat dissipating holes.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a lead-acid start-stop battery with a cooling cover. Background technique [0002] Start-stop batteries have been widely used in foreign developed countries to reduce fuel consumption and reduce air pollution. Start-stop batteries in cars belong to the micro-mixed series of hybrid power. As power, when waiting for a green light at a red light intersection, the engine of the car is still idling under normal circumstances, so it continues to use oil, and the air is still polluted by the exhaust emitted by the car, but the car is equipped with a start-stop battery When waiting for a green light at a red light intersection, the fuel-consuming engine stops running, and the lights, air conditioners and other equipment on the car are powered by the start-stop battery.

[0002] Start-stop batteries have been widely used in foreign developed countries to reduce fuel consumption and reduce air pollution. Start-stop batteries in cars belong to the micro-mixed series of hybrid power. As power, when waiting for a green light at a red light intersection, the engine of the car is still idling under normal circumstances, so it continues to use oil, and the air is still polluted by the exhaust emitted by the car, but the car is equipped with a start-stop battery When waiting for a green light at a red light intersection, the fuel-consuming engine stops running, and the lights, air conditioners and other equipment on the car are powered by the start-stop battery. When the green light is on and the car starts to pass the intersection, the start-stop battery still provides energy , and at this time the battery is working in a high-current discharge state. When the car has completely passed the intersection and the driving speed reaches a certain value, the fuel-consuming engine system will start to run, providing driving power for the car, and at the same time starting to generate electricity for the start-stop battery. The existing start-stop battery has relatively high energy, high storage energy density, and long service life, but the battery will generate a lot of heat during charging and discharging, which will cause the temperature of the battery electrode group to be too high, thus affecting the battery electrode. The working efficiency and service life of the group, for this reason, we propose a lead-acid start-stop battery with a cooling cover
