Abstract

The invention relates to a battery calorific value testing method and a battery calorific value testing device. The method comprises the steps of discharging a battery to be tested, heating the battery to be tested with a preset heating power, obtaining temperature information of the battery to be tested in the process of discharging and heating through a temperature measuring device, obtaining anintegral area of excess temperature of the battery to be tested in the process of discharging and heating according to the change of the temperature of the battery to be tested with time in the process of discharging and heating, and thus obtaining a calorific value of the battery to be tested in discharging according to the integral area of the excess temperature of the battery to be tested andthe preset heating power. The battery calorific value testing method and the battery calorific value testing device provided by the invention have the advantages of a simple structure, rapid test, a reliable test effect, high efficiency, high practicality, a low process requirement, low test cost and good engineering practice significance and are worthy of widespread use.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a battery calorific value testing method and a battery calorific value testing device. Background technique [0002] Batteries, such as nickel-hydrogen batteries, are widely used in satellite systems. Due to the heating characteristics of batteries during work, in satellite control systems, it is often necessary to take thermal control measures for important components in the satellite, such as nickel-hydrogen batteries. Ensure its proper working temperature to prolong its service life. However, the calorific value of nickel-hydrogen and other batteries during the working process often changes with the discharge current. Therefore, to take effective thermal control measures for them, it is necessary to measure the calorific value of nickel-hydrogen batteries under various discharge currents. In the prior art, an adiabatic method is usually used to measure the calorific...
