Problems solved by technology

Under normal circumstances, the time and service life of the notebook battery are good. However, due to personal habits of using notebook computers in practical applications, it is easy to over-discharge the notebook battery. After many times or even one over-discharge of the notebook battery, the notebook battery The stability of the power supply system of the battery will be destroyed, which will greatly affect the work of using the notebook. The instability of the notebook battery greatly reduces the portability of the notebook. The invention provides an automatic recovery method after the notebook battery is over-discharged. In the stored notebook power supply system, by adding a battery switch to extend the standby storage time of the notebook battery, the automatic recovery of the battery becomes a basic function of the notebook. How to realize automatic recovery after the battery with the battery switch is over-discharged, And does not affect the normal work of the battery

Embodiment Construction

[0013] The present invention will be further described in conjunction with the accompanying drawings.

[0014] figure 1 It shows that using an automatic recovery method after the notebook battery is over-discharged, the notebook battery communicates with the notebook through SMBUS, and sets the PACK pin and the DET pin for the notebook battery and the notebook. The PACK pins include PACK+ pins and PACK- pins ; PIN1 pin is set next to the PACK+ pin of the notebook, and the 3pin switch K1 is set in the connection between the notebook battery and the PACK+ pin of the notebook. The location is at the connection of the PIN1 pin of the notebook; the connection between the PIN1 pin and the DET pin is set to detect the presence of the battery and the charging protection circuit.

[0015] refer to figure 2 The EC controller is set in the detection battery existence and charging protection circuit, and the MOS tube connected to the second tube is an N-channel enhanced MOS tube. Resi...

Abstract

The invention discloses an automatic recovery method used after laptop battery over-discharge and belongs to the field of power supply of computers. A 3-pin switch for a battery is arranged for a laptop battery, is provided with a switching-on position and a switching-off position and is provided with a circuit for detecting the existing situation and charging protection of the battery. The state of the battery can be accurately judged through the arranged parts, so that when the battery exists, the battery switch is in an 'on' state, a laptop can achieve pre-charge by playing a pre-charge function after battery over-discharge, damage to the laptop battery itself is prevented during over-discharge of the laptop battery, the stability of a power supply system of the laptop battery is ensured, and daily usage of the laptop is facilitated.

Description

technical field [0001] The invention discloses an automatic recovery method after a battery is over-discharged, which belongs to the field of computer power supply, in particular to an automatic recovery method for a notebook battery after an over-discharge. Background technique [0002] During the over-discharge process of the battery, if the battery discharge termination voltage value is exceeded, the internal pressure of the battery may increase when the battery continues to discharge, and the reversibility of the positive and negative active materials is damaged. Generally speaking, the positive and negative active materials are reversible. Even if it is charged, it can only be partially restored. A certain amount of lithium ions must be kept in the negative electrode to maintain the stability of the structure. Over-discharge will cause more lithium ions to move out, destroying the stable structure of the negative electrode, and the capacity will also be significantly att...
