Problems solved by technology

[0004] The disadvantages of it are: single cell forming (or testing) method and its equipment, because only one single cell can be formed (or testing) at a time, the production efficiency is too low, many equipments need to be used in production, the cost is high and It occupies a large area, and the voltage of the single battery is too low. When discharging, it is difficult to invert the electric energy into AC power that can be received by the grid and feed it back to the grid. Lack of effective monitoring circuit control can easily cause overcharging or overdischarging of the single battery, so it is inconvenient to use. Generally, it is only suitable for overcharging-resistant batteries, such as lead-acid batteries. For batteries that are not resistant to overcharging, the application is very limited. , unless the voltage of each single battery is manually measured, and if it is found to be high or low, it will be disconnected. The operation is troublesome, time-consuming and unreliable

Abstract

The invention relates to a method and equipment for forming and testing batteries, in particular to the method and the equipment for forming and testing series-connected and monitored batteries, and is applicable to formation and testing of various kinds of secondary batteries. The invention is characterized in that: the batteries to be formed or tested are connected in series and then formed or tested; a single battery is connected with a voltage monitoring control and equalization charging circuit; the voltage of each single battery can be monitored; the single battery is prevented from being over-charged and over-discharged; and the single battery is subjected to equalization charging. Compared with the prior art, the invention has the advantages of high production efficiency, small occupation area, energy conservation, substantially-unlimited application range, and simple, convenient, time-saving and reliable operation.

Description

(1) Technical field [0001] The invention relates to a series monitoring battery formation test method and its equipment, which is a battery formation and testing method and equipment, and is suitable for the formation and testing of various secondary batteries. (2) Background technology [0002] A battery is a device that converts chemical energy into electrical energy. The secondary battery is a rechargeable battery, also called a battery. supercapacitors etc. During the production process of these batteries, formation and testing are generally carried out. Formation is the process of charging and activating the battery after the secondary battery (hereinafter referred to as the battery) is assembled. The battery is charged and discharged to check whether the capacity, charge and discharge performance of the battery meet the requirements. [0003] According to the different types of batteries, there are many methods and different equipments for the existing battery format...
