Abstract

The battery storage module with a microcomputer chip is characterized in that it includes an input node (IN1), an output node (IN2), a fuse (LF), a second resistor (R2), a first resistor (R1), a first capacitor ( C1), the first inductor (L1), the first diode (D1), the second capacitor (C2), the second diode (D2), the third diode (D3), the zero sampling resistor (R20 ), No. 1 sampling resistor (R21), switch (K1), rechargeable battery (BAT), power supply location (GND1), microcontroller (PIC12F510), bootstrap node (P), sampling node (S), optocoupler (OC1 ). An electric vehicle has the aforementioned battery storage module with a microcomputer chip. The invention is low in cost, flexible in application, long in service life, not easy to damage, stable and reliable, and can use the electric energy of the DC power supply to test whether there is an open circuit in the "diode whose positive pole is connected to the high voltage pole of the DC power supply" when the DC power supply is running. Reliable detection of open circuit of fuse through bypass.

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.

[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
