TESTING APPARATUS AND CHARGING SYSTEM

A testing apparatus is configured to perform a charge and discharge test on a first energy storage and charging device having a first charging interface and a second energy storage and charging device having a second charging interface. The testing apparatus includes a connecting unit configured to connect power interfaces in the first charging interface and the second charging interface, so as to electrically connect the first energy storage and charging device and the second energy storage and charging device; and a test control unit configured to connect to signal interfaces in the first charging interface and the second charging interface to separately communicate with the first energy storage and charging device and the second energy storage and charging device, so as to control the first energy storage and charging device and the second energy storage and charging device for the charge and discharge test.
