Embodiment Construction

[0019] An embodiment of a liquid-rich parking air-conditioning battery of the present invention is a liquid-rich maintenance-free lead-acid battery, which uses the main raw materials for mixing paste including high-strength short fibers, PBX-51 carbon black and fumed silica solution, high-strength short-term The length of the fiber is 3-4mm, the fineness is 0.8-1.2D, and the specific surface area of ​​PBX-51 carbon black is 120±10m 2 / g, the main content of the fumed silica solution is 18%-22%, and the viscosity is ≤200mPa.s. The oxidation degree of lead powder is 76±3%, and the apparent density is 1.25-1.45g / cm 3 , Fe content ≤ 0.001%, water absorption rate 100-120ml / Kg. Add 0.5% antimony trioxide to the positive electrode to prepare the lead paste, and the apparent density of the positive electrode lead paste is 4.5g / cm 3 , Penetration is 18-20mm, moisture content is 10.5±0.5%. The apparent density of negative electrode paste is 4.45g / cm 3 , Penetration is 18-20mm, moist...

Abstract

The invention relates to a flooded parking air conditioner battery and a working condition simulation cycle test method thereof. The invention belongs to the technical field of lead-acid storage batteries. The invention mainly solves the problem that no special battery working condition simulation cycle test method is provided for the novel flooded parking air-conditioning battery at present. The method is mainly characterized by comprising the following steps: (1) performing discharging for 6 +/-0.1 hours at a constant current of 4 +/-0.1 A; (2) performing charging for 6 +/-0.1 h at a constant voltage of 14 +/-0.1 V and a limited current of 70 +/-1A; (3) performing discharging at constant current of 27 +/-0.1 A for 3 +/-0.1 h; (4) performing charging at constant voltage of 14 +/-0.1 V and limited current of 70 +/-1A for 6 +/-0.1 h; (5) forming a complete test cycle according to the steps (1)-(4), and judging that the test is ended when the terminal voltage in the cycle process is lower than the lowest protection voltage of the rich liquid parking air-conditioning battery; in addition, after 50 cycles every time, performing a low-temperature test of-18 +/-1 DEG C at 0.6 Icc, determining that the final voltage is not lower than the minimum starting voltage of the whole vehicle after the Icc discharges for 30 s, or else, determining that the test is terminated. The method is mainly used for accurately and effectively evaluating the performance of the parking air conditioner battery.

Description

technical field [0001] The invention belongs to the technical field of lead-acid storage batteries, and in particular relates to a liquid-rich parking air-conditioning battery and a working condition simulation cycle test method thereof, which are used for the research and evaluation of the liquid-rich parking air-conditioning battery. Background technique [0002] With the improvement of living standards, the batteries on trucks are no longer just enough to start the engine. In order to make sports cars more comfortable and convenient, there are more and more electronic devices on trucks, such as inverters, entertainment systems, and parking heaters. , parking air conditioners and other electronic equipment are large electricity consumers. [0003] At the same time, in order to increase the selling points of vehicles, commercial vehicle OEMs are gradually incorporating the additional air-conditioning requirements of end customers into the normal use of vehicles, and battery...
