Embodiment Construction

[0036] see figure 1 Shown is a preferred embodiment of the battery simulator of the present invention, which includes:

[0037] An AC-DC conversion unit 11, connected to an AC power source, converts AC power into DC power;

[0038] An adjustable DC conversion unit 12 is connected to the AC-DC conversion unit 11 and includes a DC converter 121, an output capacitor 122 and a controller 123; wherein the DC converter 121 is connected to the AC-DC conversion unit 11 The output end, through the control of the controller 123, changes the output DC voltage of the AC-DC conversion unit 11 and stores it in the output capacitor 122;

[0039] A programmable load 13 is connected to a DC power bus DC BUS together with the output capacitor 122 of the adjustable DC conversion unit 12, and the DC power bus DC BUS is connected to a DC power terminal of an external power supply;

[0040] A control and communication unit 14, electrically connected to the pulse width modulation input terminal o...

Abstract

The invention provides a battery stimulation device comprising an AC-DC conversion unit, an adjustable type DC conversion unit, a programmable load, and a control and communication unit. The control and communication unit is electrically connected with a pulse width nodulation input end of a controller of the adjustable type DC conversion unit, and is connected with an external computer by a computer communication interface. Therefore when a user selects the corresponding battery charging and discharging stimulation modes according to the rechargeable battery of the power supplier of the machine to be detected, the control and communication unit is automatically used to control the adjustable-type AC-DC conversion unit and the programmable load mode battery charging and discharging states, then the external power can carry out the machine detection program. In addition, the power of the DC conversion unit is provided by the AC-DC conversion unit, therefore no other battery used for the power supply is required, and the integral structure can be effectively reduced.

Description

technical field [0001] The invention relates to a battery simulation device, in particular to a battery simulation device with a simple structure. Background technique [0002] Many high-wattage power supplies that use rechargeable batteries as the main power source or backup power source (such as uninterruptible power supply systems, power supplies with built-in backup batteries), must actually be tested for a long time with the battery before shipment, and the power supply must be confirmed. Whether the device can smoothly charge and discharge the rechargeable battery. [0003] like Figure 4A and Figure 4B Shown is a common battery charge and discharge characteristic test, when the battery is discharged, the battery voltage will gradually drop until it reaches the cut-off voltage, and then stop discharging; when the battery is charging, the battery voltage will gradually rise until it reaches the floating charge voltage, and Maintain this potential stably until the bat...
