In an embodiment, as shown in fig. 1, the control module 110 is connected to control ends of the first switch module 121, the second switch module 122, and the third switch module 123, and is used for controlling the on/off of the first switch module 121, the second switch module 122, and the third switch module 123 to realize on/off combinations of different test paths.
The power supply module 130 is configured to charge the electronic device, and the power consumption module 140 is configured to consume electric energy of the electronic device.
By way of example, the power module 130 may include an energy storage device including an electrical energy storage unit, such as one or more batteries. The power supply module 130 may also include a power input device that may obtain electrical energy from an external source, such as a power grid, a generator, an energy storage device connected to a power supply device, a solar cell, etc., for example, a charger.

When the control module 110 controls the dc charging switch 1212 to be closed, the dc power supply module 132 outputs a dc voltage to charge the electronic device.
For example, the control module 110 may control the ac charging switch 1211 and the dc charging switch 1212 to be simultaneously closed, and the ac power module 131 and the dc power module 132 to simultaneously charge the electronic device.
For example, the dc power module 132 may include multiple dc outputs, and may provide a dc voltage output to the electronic device at the same time, or may provide a dc voltage output to the electronic device separately.

The first end of the ac power switch 1222 is electrically connected to the ac voltage output terminal of the electronic device, and the second end of the ac power switch 1222 is electrically connected to the ac power module 142.
For example, when the control module 110 controls the dc power switch 1221 to be closed, the electronic device outputs a dc voltage to the dc power module 141 to consume the electric power of the electronic device. When the control module 110 controls the ac power switch 1222 to be closed, the electronic device outputs a dc voltage to the ac power module 142, and the ac power module 142 consumes the electrical energy of the electronic device.

Under the test condition, when the initial SOC (State of Charge) of the electronic device is less than 100%, the control module 110 controls the dc charging switch 1212 to be closed, so as to Charge the electronic device with the dc power supply module 132. When the current SOC of the electronic device is equal to 100%, the control module 110 controls the dc charging switch 1212 to be opened and controls the dc power supply switch 1221 to be closed, and the dc power module 141 consumes the electric energy of the electronic device to discharge the electronic device. When the current SOC of the electronic device is equal to 0%, the control module 110 controls the dc charging switch 1212 to be closed and the second switch module 122 to be opened, so that the dc power supply module 132 charges the electronic device, and sequentially and circularly charges and discharges the electronic device.

Under the test condition, the control module 110 controls the ac charging switch 1211 to be closed when the initial SOC of the electronic device is less than 100% so as to charge the electronic device by the ac power supply module 131. When the current SOC of the electronic device is equal to 100%, the control module 110 controls the ac charging switch 1211 to open and controls the ac power switch 1222 to close, and the ac power module 142 consumes power of the electronic device to discharge the electronic device. When the current SOC of the electronic device is equal to 0%, the control module 110 controls the dc charging switch 1212 to be closed and the second switch module 122 to be opened, so that the ac power supply module 131 charges the electronic device, and sequentially and circularly charges and discharges the electronic device.

When the current SOC of the electronic device is equal to 100%, the control module 110 controls the first switch module 121 to be turned off, the load of the program-controlled dc power module 141 is a full load value or an overload value of the electronic device, and the on time and the off time of the dc power switch 1221 are set to discharge the electronic device. When the current SOC of the electronic device is equal to 0%, the control module 110 controls the dc power supply switch 1221 to be opened and the dc charging switch 1212 to be closed, so as to charge the electronic device, and sequentially and circularly charge and discharge the electronic device. The cyclic condition of the direct current output of the electronic equipment under the full load/overload condition can be tested through the loading and unloading test under the full load/overload condition of the direct current output.
In one embodiment, as shown in FIG. 2, when the control module 110 and the electronic device receive a test instruction for a load/unload test condition under an AC output full load/overload condition, the test condition is triggered under the test instruction. Under the test condition, when the initial SOC of the electronic device is less than 100%, the control module 110 controls the first switch module 121 to be closed, so as to charge the electronic device by the dc power supply module 132.
