Battery stimulation device

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...

AI Technical Summary

Problems solved by technology

[0005] 1. The charging and discharging time is too long

[0006] 2. Overcharging or overdischarging is easy to damage the battery

[0007] 3. The battery is large in size, and it is not easy to replace if it is damaged due to testing

[0009] Although the above-mentioned battery charge and discharge simulator can simulate the charge and discharge characteristics of the rechargeable battery used in the power supply, instead of the physical rechargeable battery for testing, since the user must execute special software through the main control device to complete the setting and simulation, it is not suitable for general use. As far as those are concerned, it cannot be widely used due to its poor flexibility of use and high cost of construction, and it is necessary to further improve it.
