Problems solved by technology
[0008] The purpose of the present invention is to solve the existing battery charging method. There are multiple batteries in parallel charging without protection, which will impact and damage the battery cell. The single battery is charged alternately. The overall charging time is long and the efficiency is low. Two power supply chips Charge two batteries separately, the loss is relatively large, and the problem of occupying redundant devices and PCB space

Embodiment Construction
[0059]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0060] Such as figure 1 As shown, the multi-cell detachable battery detection method is carried out according to the following steps:
[0061] Step 1, insert the rechargeable battery, initialize the system and peripherals;
[0062] Step 2, whether the T1 time interval is up, if yes, go to the next step, if not, go to step 6;
[0063] Step 3, collecting multiple batteries AD (referring to the amount of original analog data);
[0064] Step 4, control the dis...

The invention discloses a method for detecting, charging and discharging multiple detachable batteries. The method comprises the following steps of: step 1, inserting batteries, and initializing a system and peripherals; step 2, judging whether a time interval T1 is up or not, if so, executing the next step, and if not, jumping to step 6; step 3, performing AD acquisition on the multiple batteries; step 4, controlling display of an indicator lamp; step 5, when the multiple batteries are inserted or pulled out, performing battery parallel management and control distribution; step 6, judging whether a T2 time interval is up or not, if so, executing the next step, and if not, jumping to step 8; step 7, recognizing the reverse insertion of the batteries; step 8, judging whether a time interval T3 is up or not, if so, executing the next step, and if not, jumping to step 10; step 9, performing AD over-temperature detection on the batteries; step 10, judging whether a time interval T4 is up or not, if so, executing the next step, and if not, jumping to step 14; step 11, acquiring charging and discharging information of a power supply chip every T4 time; step 12, configuring charging and discharging of the power supply chip; and step 13, performing power supply chip state abnormity identification.
Description
technical field [0001] The invention relates to the technical field of charging, in particular to methods for detecting, charging and discharging multiple detachable batteries. Background technique [0002] In the existing mobile power supply, the battery cells are closed and cannot be removed, and multiple sections are directly welded side by side, so the safety control of the battery cells cannot be achieved. With flexible capacity requirements, open-type batteries that can be inserted and pulled out can be directly connected in parallel. Without protection, the battery cell will be damaged by impact. The charging current of a single battery is relatively small, and the next battery can only be charged after one battery is fully charged. The overall charging time is longer, and the loss of the two power supply chips is relatively large when the battery is charged separately, and it takes up redundant components and PCB space. [0003] It can be seen that the existing batt...
