Abstract
The invention relates to a charge-discharge protector of a high-capacity rechargeable battery. The charge-discharge protector comprises a high-capacity rechargeable battery (1), a switching power supply isolation charger (2), a switching power supply isolation discharger (3), a power output terminal (4), a power input terminal (5) and a power ground (6), wherein the power input terminal (5) is used for achieving charge management on the high-capacity rechargeable battery (1) by the switching power supply isolation charger (2), the high-capacity rechargeable battery (1) is connected to the power output terminal (4) through the switching power supply isolation discharger (3) to achieve discharge, and ground lines of the switching power supply isolation charger (2) and the switching power supply isolation discharger (3) are connected to the power ground (6).
Description
Technical field:
The present invention relates to a kind of Large Copacity chargeable battery charge and discharge protector, belong to cell safety application.
Background technology:
Currently, Large Copacity can charge and discharge battery applications increase, and high capacity cell is big due to its capacitance, safety is more specifically important, when needs more capacity or voltage, 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 present invention relates to a kind of Large Copacity chargeable battery charge and discharge protector, to realize battery purpose of safe discharge and recharge when connection in series-parallel uses.
For realizing above-mentioned purpose, the present invention adopts the following technical scheme that
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.
nullBelow in conjunction with accompanying drawing，Technical construction and the method for the present invention are described: power input terminal (5) is isolated charger (2) by Switching Power Supply and Large Copacity chargeable battery (1) is realized Charge Management，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 with being connected to power supply (6)，During charging，Power supply is through isolated variable，Isolate charger (2) by Switching Power Supply and Large Copacity chargeable battery (1) is carried out special Charge Management，At this moment Large Copacity chargeable battery (1) isolates the reliable isolation of realization between charger (2) and input power by Switching Power Supply，After Large Copacity chargeable battery (1) output then isolates discharger (3) isolation by Switching Power Supply，Output given voltage，All carry out due to input and output and be effectively isolated，Thus Large Copacity chargeable battery (1) is achieved reliably protecting，When the many groups of needs are in parallel or connect，Have only to power output terminal (4) and power input terminal (5) and (6) three, ground of power supply nodes are carried out connection in series-parallel.
Beneficial effects of the present invention: switch isolation, safe and reliable, although reducing a part of power-efficient, but considerably increase safety and the life-span of battery applications.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
Detailed description of the invention:
In order to make technical scheme clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail, instantiation described herein, only in order to explain the present invention, is not limited to the present invention.
Embodiment:
Refer to shown in accompanying drawing 1, power input terminal (5) is isolated charger (2) by Switching Power Supply and Large Copacity chargeable battery (1) is realized Charge Management, 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 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 Large Copacity chargeable battery (1) is realized Charge Management, 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 with being connected to power supply (6).
