Embodiment Construction

[0045] The present invention will be further described below in conjunction with embodiment.

[0046] A storage battery automatic charging and discharging method, such as figure 1 shown, including the following steps:

[0047] Step 1: Set the battery discharge cycle through the input module.

[0048]Step 2: The microcontroller detects whether there is an external command input.

[0049] Step 3: When an external command input is detected, the single-chip microcomputer further analyzes that the external command is a charge or discharge command, and enters step 4; when no external command input is detected, the voltage detection module collects the battery voltage U0, and enters step 6; among them, U0 It is the voltage sampling value of the battery.

[0050] Step 4: When the external command analyzed by the single-chip microcomputer is a charging command, the single-chip microcomputer controls the charging control module to charge the storage battery; when the external command...

Abstract

The present invention provides a storage battery automatic charge and discharge apparatus and method, belonging to the field of charge and discharge apparatuses. The charge and discharge apparatus includes a single chip microcomputer, a signal conditioning module, a current detection module, a voltage detection module, an A / D conversion module, a switch control module, a charge control module, a voltage conversion module, an input module, a clock module, a power-off detection module, and a communication module. The input module is used for setting a discharge period of the storage battery. The communication module is used for receiving an external instruction, and delivering a storage battery charge or discharge state to an external communication device. The signal conditioning module is used for conditioning a voltage signal and a current signal that are to be sampled. The current detection module is used for detecting a current of the storage battery. The voltage detection module is used for detecting a voltage of the storage battery. The A / D conversion module performs analog-digital conversion on the collected voltage and current. The switch control module controls the storage battery to discharge. The charge control module controls the storage battery to charge. The single chip microcomputer is used for processing data and controlling the storage battery charge and discharge.

Description

technical field [0001] The invention relates to the field of charging and discharging devices, in particular to a storage battery automatic charging and discharging device and a method thereof. Background technique [0002] Since their introduction in the 1860s, batteries have been used in a wide variety of devices, including electric vehicles, various portable devices and uninterruptible power supply systems. In today's application of new energy, battery is a reusable energy storage device, and its performance and technical development have attracted widespread attention from the whole society. In the actual application of the battery, since the charging and discharging process of the battery is an extremely complex electrochemical reaction process, the battery will often be overcharged / discharged or undercharged / discharged after long-term charging and discharging, which seriously affects the use of the battery life. [0003] During the charging process of the battery, th...
