Abstract

The invention discloses a battery charging and discharging test system. The battery management module collects battery data of each single battery cell and obtains a single voltage maximum value and asingle voltage minimum value of each single battery cell through calculation; the first upper computer obtains the maximum monomer voltage and the minimum monomer voltage according to the monomer voltage maximum value and the monomer voltage minimum value and sends the maximum monomer voltage and the minimum monomer voltage to the charging and discharging machine, the charging and discharging machine sends the maximum monomer voltage and the minimum monomer voltage to the second upper computer, and the second upper computer controls the charging and discharging machine to control battery charging with the maximum monomer voltage and control battery discharging with the minimum monomer voltage. The system is simple in structure and convenient to set, the second upper computer is arranged to control the charging and discharging motor to perform charging and discharging, overcharging and overdischarging of the system are prevented, and the test safety of the battery cell is improved.

Description

technical field [0001] The invention relates to the technical field of battery testing, and more specifically relates to a battery charging and discharging testing system. Background technique [0002] Today, as environmental problems are becoming increasingly prominent, the new energy industry continues to develop. Lithium batteries, which are relatively mature in technology and relatively superior in performance in the industry, are becoming more and more familiar to people. However, existing battery charge and discharge test systems generally use total voltage information for charge and discharge. Control, there is a risk of overcharging and overdischarging, and the safety of battery cell testing is low. Contents of the invention [0003] In view of this, the object of the present invention is to provide a battery charge and discharge test system to solve the problems of overcharging and overdischarging in the existing battery charge and discharge test system and low ba...
