Problems solved by technology
Therefore, there are many versions of the printed circuit board (PCB) of the battery charger, and the production cost increases.
At the same time, the accuracy of the battery voltage detection result of the existing battery charger is low, and it does not have the function of online monitoring of the charging current, which not only increases the power consumption, but also cannot be corrected when there are charging abnormalities such as short circuit, overvoltage and undervoltage. Battery protection to avoid safety hazards such as fire caused by abnormal charging

The embodiment of the invention discloses a battery charging control circuit. The battery charging control circuit comprises a battery charging circuit which is used to pre-charge a battery when detecting that the battery is connected with the battery charging circuit, a voltage detecting circuit which is connected with the battery charging circuit and is used to detect the first voltage amplitudeof the battery during a pre-charging process and output the first voltage amplitude to a microprocessor, the microprocessor which is connected with the voltage detecting circuit and is used to determine a charging parameter for the battery charging circuit to standardly charge the battery according to the first voltage amplitude, and a current detecting circuit which is used to detect the currentamplitude of the battery charging circuit during the standard charging process and output the current amplitude to the microprocessor. The battery charging control circuit is simplified. Power consumption is reduced. The reliability and safety of battery charging are improved.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a battery charging control circuit. Background technique [0002] The existing battery charging control and protection technical solution is to use the flyback switching power supply based on the primary side detection to realize AC / DC conversion, and the DC side realizes the charging and discharging control and protection of the battery through a dedicated battery control and management chip, or uses a low The low-cost microprocessor (Microcontroller Unit, MCU) realizes battery charging control, online monitoring and protection. In the prior art, by configuring different resistors to identify the type of battery pack to determine the charging time, and configuring different resistors to measure the battery voltage to determine the number of cells in the battery pack, such as 3-7 batteries (3.6-8.4V), 8-15 batteries (9.4-18V). Therefore, there are many versions of the print...
