Automatic activation and charge-discharge management system and method for terminal nickel-metal hydride battery

Abstract

The invention discloses an automatic activation and charge-discharge management system and method for a terminal nickel-metal hydride battery. The system comprises a human-computer interaction unit, amain control unit, a nickel-metal hydride battery unit, an upstream communication unit, a functional interface unit and a metering unit, wherein the nickel-metal hydride battery unit is connected with a charge power supply interface inside the functional interface unit; the nickel-metal hydride battery unit is further used for providing working voltage for the main control unit, the communicationunit and the interface unit; the main control unit is connected with a microphone through the upstream communication unit, and the main control unit is further connected with an earphone and a serialport communication unit; and the main control unit comprises a charge circuit, an active discharge circuit, a temperature detection circuit and a control management unit. The identified conditions ofcharge and discharge events are realized, and charge and discharge of the battery are disconnected under the condition of inappropriate temperature, self-management and automatic activation capacities of the terminal nickel-metal hydride battery are realized at the minimum hardware cost, the system is novel in structure and smart in conception, reliable operation of the terminal nickel-metal hydride battery is guaranteed, and the system has good application prospects.

Description

technical field [0001] The invention relates to the technical field of nickel-metal hydride battery charging, in particular to a system and method for autonomous activation, charge and discharge management of a terminal nickel-hydrogen battery. Background technique [0002] At present, terminal manufacturers basically only have two means of voltage monitoring and charging for the management of Ni-MH batteries. Moreover, the implementation of these two means is too simple. The cut-off condition of charging does not consider the influence factors such as ambient temperature and individual differences. Record and display the charge and discharge times, current working status, and remaining power of Ni-MH batteries, and remind customers to replace them in a timely and effective manner. [0003] At present, the technical management methods of power companies are relatively backward, and the procurement and installation process is also very complicated. The centralized procureme...

This makes the self-discharge of the Ni-MH battery itself more serious, and also makes the battery passivated to a certain extent. If the terminal has a power outage in this state, the remaining power of the Ni-MH battery itself will be difficult to support the terminal. Capability of "1min working t
