Power cell source test method

Abstract

The invention discloses a method for testing dynamic battery sources, which relates to the battery sources testing technique field. The invention solves existing technique problems that bigger errors are existed in tests and calculations of working voltages, electric currents of dynamic batteries, and battery energy SOC, testing and reflecting speed is low, immediate alarming hints and monitoring management for working process are not available, which leads to damages for a single battery due to battery over pressure and battery under pressure. The method comprises initializing a system, setting standards to compare with electric parameters, comparing the electric parameters, comparing temperature parameters, waiting for interrupting orders, comparing, marking, and storing collected periodic electric voltages, the electric currents, temperature data of each battery of the battery sources, executing alarming operations according to marking data. The invention can test precisely and rapidly the working voltages, the electric currents, temperature, and battery energy SOC of the dynamic batteries. The invention can avoid battery over discharging and battery overcharge and can send sound and light alarm hints.

Description

technical field [0001] The invention relates to the technical field of measurement of power battery sources. Background technique [0002] The power battery source refers to a battery pack that can provide powerful power. It is suitable for applications requiring high-energy battery power, such as hybrid vehicles, electric vehicles, portable radios, and mobile data base stations. The power battery pack is generally composed of multiple batteries connected in series. After multiple batteries are connected in series, there will be unbalanced charging and discharging of each battery during use. The specific performance is that some batteries are overcharged or overdischarged. If not controlled, some batteries will be damaged and affect the performance and life of the entire battery pack. For example, the energy SOC (State of Charge, referred to as SOC, that is, the battery power) of the battery will be lower than that of other batteries. If the discharge continues, the voltag...
