Abstract

The invention discloses a battery detection power supply, and an output control method and device. The power supply comprises a main controller, a DC bus, a DC / DC module array and an output bus. The main controller is used for receiving a configuration file sent by an upper computer and outputting a switch control instruction by analyzing the configuration file; the DC bus forms a direct-current voltage of a preset voltage level; the DC / DC module array comprises a plurality of power modules which are distributed in rows and columns, the input end of each power module is connected with the DC bus, the output end of each power module is connected with an output bus through a change-over switch, and the change-over switch is configured to be switched on or off according to the switch controlinstruction, so that the voltage of the output bus is matched with an output voltage parameter, and the current is matched with an output current parameter; and the output bus is used for connecting ato-be-detected battery. During detection, the requirements of different voltages and different currents can be met by configuring different configuration files, so that the requirements of charging and discharging according to the process requirements of the battery are met.

Description

technical field [0001] The present application relates to the field of power supply technology, and more specifically, relates to a battery detection power supply and its output control method and device. Background technique [0002] With the rapid development of battery technology, batteries have been widely used in production and life. They are no longer limited to small electrical equipment such as mobile phones and notebook computers, but to large mobile electrical equipment such as passenger cars, trucks, and even ships. expand. Especially recently, with the requirements of environmental protection, electric vehicles have become an important application field of batteries. [0003] Since the safe and stable operation of batteries is related to the safety of people's lives and properties, the quality of these batteries must be guaranteed no matter what occasion they are used in. In order to ensure the quality of the battery, the performance of the battery must be test...
