Constant temperature lead acid accumulator

Abstract

The invention belongs to the storage battery field, in particular to a constant temperature lead-acid storage battery, which is characterized in that a constant temperature heating apparatus is arranged at the bottom part of the original lead-acid storage battery to ensure that the storage battery works in the nominal temperature range, the constant temperature heating apparatus can be a constant temperature backing plate, the battery backing plate is a heat-conducting and flame-retarding gasket, a constant temperature heating element is disposed in an interlayer of the battery gasket, the tail end of a leading-out wire of the constant temperature heating element is a power supply connector, and the power supply connector is directly connected with a charging circuit of the storage battery. The constant temperature heating element is electrified for operation in the process of charging and discharging of the storage battery, so as to ensure that the temperature of the storage battery is in the constant temperature zone, and the working temperature of the storage battery is kept in the constant temperature range and will not be influenced by low temperature in terms of the charging and discharging performances of the storage battery any longer. The invention is simple and convenient, and can be applied to electric vehicles with all lead-acid storage battery specifications.

Description

technical field [0001] The invention belongs to the accumulator category. Background technique [0002] With the rapid development of modern urban construction and the enhancement of people's awareness of energy conservation and environmental protection, economical, convenient and environmentally friendly electric vehicles are favored, and have become the means of transportation that more and more people choose to travel. However, the electric vehicle batteries currently produced generally use lead-acid batteries. With their inherent characteristics, the batteries are more sensitive to temperature changes. The lower the temperature, the lower the charging and discharging capabilities of the batteries. The charge and discharge capacity is only 60% of the normal temperature of 25 degrees Celsius, especially in the winter in northern my country, the temperature drops greatly, the charge and discharge capacity of the battery is obviously insufficient, which seriously affects the ...

However, the electric vehicle batteries currently produced generally use lead-acid batteries. With their inherent characteristics, the batteries are more sensitive to temperature changes. The lower the temperature, the lower the charging and discharging capabilities of the batteries. The charge and discharge capacity is only 60% of the normal temperature of 25 degrees Celsius, especially in the winter in northern my country, the temperature drops greatly, the charge and discharge capacity of the battery is obviously insufficient, which seriously affects the discharge time of the battery, and the mileage of the electric vehicle is greatly shortened. It brings a lot of inconvenience to the majority of electric vehicle users, and also sets up an obstacle for the development of electric vehicles

For this reason, people think hard about this problem, add some additives inside the battery, change the battery formula and make colloidal batteries. However, due to the inherent characteristics of lead-acid batteries, they cannot fundamentally solve the impact of temperature difference on the charging and discharging time of batteries.
