Description
technical field:
The utility model relates to a kind of Large Copacity chargeable battery charge and discharge protector, belongs to cell safety application.
background technology:
Current, Large Copacity can charge and discharge battery applications increase, and high capacity cell due to its capacitance large, safety is more specifically important, when needs more Large Copacity or voltage time, need serial or parallel connection, traditional method is direct connection in series-parallel, because of individual cells parameter differences, when causing battery series-parallel connection to apply, life-span is short, deterioration of safety.
summary of the invention:
The utility model relates to a kind of Large Copacity chargeable battery charge and discharge protector, to realize the object of battery safe discharge and recharge when connection in series-parallel uses.
For realizing above-mentioned object, the utility model adopts following technical scheme:
A kind of Large Copacity chargeable battery charge and discharge protector, comprises:
Large Copacity chargeable battery (1), Switching Power Supply isolation charger (2), Switching Power Supply isolation discharger (3), power output terminal (4), power input terminal (5), power supply ground (6); As shown in Figure 1.
Below in conjunction with accompanying drawing, technical construction of the present utility model and method are described: power input terminal (5) is isolated charger (2) by Switching Power Supply and realized Charge Management to Large Copacity chargeable battery (1), Large Copacity chargeable battery (1) electric discharge is then isolated discharger (3) by Switching Power Supply and is connected to power output terminal (4) realization electric discharge, Switching Power Supply isolation charger (2) and Switching Power Supply isolation discharger (3) ground wire are with being connected to power supply (6), during charging, power supply is through isolated variable, isolate charger (2) by Switching Power Supply and special Charge Management is carried out to Large Copacity chargeable battery (1), at this moment Large Copacity chargeable battery (1) is isolated between charger (2) and input power by Switching Power Supply and is realized reliably isolating, after Large Copacity chargeable battery (1) exports and then isolates discharger (3) isolation by Switching Power Supply, export given voltage, because effective isolation has all been carried out in input and output, thus reliably protecting is achieved to Large Copacity chargeable battery (1), when the many group parallel connections of needs or series connection, only need to carry out connection in series-parallel to power output terminal (4) and power input terminal (5) and power supply (6) three, ground nodes.
The beneficial effects of the utility model: switch isolation, safe and reliable, although reduce a part of power-efficient, considerably increase security and the life-span of battery applications.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
detailed description of the invention:
In order to make the technical solution of the utility model clearly understand, below in conjunction with drawings and Examples, further describe the utility model, instantiation described herein, only in order to explain the utility model, is not limited to the utility model.
embodiment:
Refer to shown in accompanying drawing 1, power input terminal (5) is isolated charger (2) by Switching Power Supply and is realized Charge Management to Large Copacity chargeable battery (1), Large Copacity chargeable battery (1) electric discharge is then isolated discharger (3) by Switching Power Supply and is connected to power output terminal (4) realization electric discharge, and Switching Power Supply isolation charger (2) and Switching Power Supply isolation discharger (3) ground wire are with being connected to power supply (6).
Claims (1)
1. a Large Copacity chargeable battery charge and discharge protector, comprises: Large Copacity chargeable battery (1), Switching Power Supply isolation charger (2), Switching Power Supply isolation discharger (3), power output terminal (4), power input terminal (5), power supply ground (6); It is characterized in that: power input terminal (5) is isolated charger (2) by Switching Power Supply and realized Charge Management to Large Copacity chargeable battery (1), Large Copacity chargeable battery (1) electric discharge is then isolated discharger (3) by Switching Power Supply and is connected to power output terminal (4) realization electric discharge, and Switching Power Supply isolation charger (2) and Switching Power Supply isolation discharger (3) ground wire are with being connected to power supply (6).
