Battery power storage module provided with micro computer chip and portable computer

Abstract

A battery power storage module provided with a micro computer chip is characterized by comprising an input node (IN1), an output node (IN2), a fuse (LF), a second resistor (R2), a first resistor (R1), a first capacitor (C1), a first inductor (L1), a first diode (D1), a second diode (C2), a second diode (D2), a third diode (D3), a No.0 sampling resistor (R20), a No.1 sampling resistor (R21), a switch (K1), a chargeable battery (BAT), a power supply grounded junction (GND1), a single chip microcomputer (PIC12F510), a bootstrapping node (P), a sampling node (S) and an optical coupler (OC1). An electric traffic tool has the battery power storage module provided with the micro computer chip. The battery power storage module is low in cost, flexible to apply, long in service life, unlikely to be damaged, stable, reliable, capable of testing whether a diode with a positive pole connected with a high-voltage pole of a direct-current power supply is disconnected by means of electric power of the direct-current power supply under the condition that the direct-current power supply operates and capable of reliably detecting disconnection of the fuse in real time by means of a bypass circuit.

Description

technical field [0001] The invention belongs to the field of applied electronics, and in particular relates to a battery storage module with a microcomputer chip and a portable computer. Background technique [0002] Instant self-test during circuit operation is of great significance to prevent circuit safety problems. There is no instant test method for diodes whose negative pole is connected to the high voltage pole of the power supply in the prior art, that is to say, when the positive pole of a diode is connected to the high voltage pole of the power supply In the case that the diode suddenly opens (due to breakdown, burning, etc.), then the circuit is difficult to detect immediately by the self-test circuit or program, which is a huge trouble for instant detection circuit failure; [0003] Adding a fuse to a single battery in the storage module of the power supply can prevent the battery from being damaged due to excessive current.

Problems solved by technology

[0002] Instant self-test during circuit operation is of great significance to prevent circuit safety problems. The existing technology does not have an instant test method for diodes whose negative pole is connected to the high voltage pole of the power supply, that is to say, when the positive pole of a diode is connected to the high voltage pole of the power supply If the diode is suddenly open circuit (due to breakdown, burning, etc.), then the circuit is difficult to detect immediately by the self-test circuit or program, which is a huge trouble for instant detection circuit failure;

[0003] Adding a fuse to a single battery in the storage module of the power supply can prevent the battery from being damaged due to excessive current. However, after the fuse breaks, the battery cannot continue to charge and discharge, which damages the vertical capacity of the battery pack. The pick-up, maintenance and replacement of the battery in the battery pack is carried out during the overall maintenance of the battery pack, and the middle section of the battery pack as a whole needs to be carried out, which is unfavorable for systems that require continuous operation of buffered electric energy
