Problems solved by technology

However, in actual use, the time spent on loading, unloading, and charging the battery occupies most of the equipment’s use time. The time spent on high-rate discharge is very short, and the high-rate discharge capacity of the equipment remains idle for a long time, resulting in extreme big waste

Embodiment Construction

[0052] In order to further understand the content of the invention, features and effects of the present invention, the following embodiments are exemplified and described in detail with the accompanying drawings as follows:

[0053] like Figure 1 to Figure 4 shown:

[0054] A high-power battery test system includes:

[0055] Charging sub-system 1 for charging M batteries and obtaining the charging data of each battery, where: M is a natural number greater than 1;

[0056] At the same time, at most M-1 batteries are discharged, and the discharge subsystem 2 that obtains the discharge data of this battery;

[0057] Accept the instruction issued by the central control sub-system, and send the battery charged by the charging sub-system to the transmission sub-system 3 in the discharging sub-system according to the instruction;

[0058] Sending working parameters to the charging subsystem and discharging subsystem, receiving the sampling data of the charging subsystem and the d...

Abstract

The invention discloses a high-power battery test system and method, and belongs to the technical field of battery testing, and the system is characterized in that the system comprises a charging subsystem which charges M batteries and obtains the charging data of each battery; and the discharging subsystem is used for discharging at most M-1 batteries at the same time and acquiring the discharging data of the batteries. According to the invention, multiple to-be-tested batteries can be charged at the same time, and the multiple to-be-tested batteries can be discharged one by one in sequence. Aiming at the test requirement of low charging rate but high discharging rate, especially the requirement of high-rate pulse discharging, the test equipment provided by the invention can greatly reduce the requirement on the number of high-power discharging equipment and reduce the test cost.

Description

technical field [0001] The invention belongs to the technical field of battery testing, and in particular relates to a high-power battery testing system and testing method. Background technique [0002] After the battery is produced, it generally needs to be tested for its performance. For the secondary battery, it is generally charged and discharged to determine its capacity, internal resistance and other properties, and use this as the basis for screening, grading, and matching the performance of the single cells in the battery pack. In the production process of batteries, there are generally processes such as chemical formation, and the essence of such processes is also to charge and discharge the battery. The process of charging and discharging the battery is generally to place the battery on a dedicated charging and discharging test equipment, each battery corresponds to a charging and discharging channel, each device can have multiple channels, and each channel can in...
