Embodiment Construction
[0084] In order to facilitate a better understanding of the purpose, structure, features and effects of the present invention, the present invention will now be further described in detail with reference to the accompanying drawings and specific embodiments.
[0085] The direct balanced charging method based on the rechargeable battery pack in the present invention, such as Figure 1 to Figure 12 shown. The direct balancing charging device for a rechargeable battery pack includes an A cell module, a B cell module, a battery pack controller, and a charging DC power supply. The A cell module is used as a bottom module, and several A cell modules are stacked on the A cell module. B cell module; A cell module contains an A cell, a parallel positive control electronic switch (SW1) connected between the charging positive input terminal of the rechargeable battery pack and the positive pole of the A cell, and the positive pole of the A cell leads out a A cell voltage monitoring sign...

The invention discloses a direct balance charging device and method for a rechargeable battery pack. The direct balance charging device comprises a battery core module A, battery core modules B, a battery pack controller and a charging direct-current power supply, wherein the battery core module A is taken as an underlying module; a plurality of battery core modules B are laminated on the battery core module A; the battery core module A includes a battery core A and a parallel positive electrode control electronic switch which is connected between a charging positive input end of the rechargeable battery pack and a positive electrode of the battery core A; a voltage monitoring signal line of the battery core A is led out of the positive electrode of the battery core A; the voltage monitoring signal line of the battery core A is connected with a battery core voltage monitoring end of the battery pack controller; and a negative electrode of the battery core A is connected with a negative output end of the rechargeable battery pack. A battery set or a supercapacitor bank can accept a relatively low charging voltage, and meanwhile, a discharging output voltage can be adjusted through a series connection and a parallel connection of modules. A secondary voltage balance operation does not need to be performed on a voltage of a single battery core or a supercapacitor in a charging process, so that charging time is shortened.
Description
technical field [0001] The invention relates to a charging system, in particular to a direct balance charging method for a rechargeable battery pack. Background technique [0002] The battery power supply device is a power source for supplying power to related electronic devices, and the power supply device may be a multicell battery having a plurality of batteries. Since a battery pack is used instead of a single cell, a high voltage can be applied, or the capacity can be increased. However, due to the charge and discharge characteristics of the battery itself, the voltage of each battery may become unbalanced over time. Voltage differences between cells in a battery pack can create cell-to-cell imbalances that deplete the capacity of the battery pack. In this regard, there are many cell balancing systems and methods to balance each cell, avoid overcharging all cells, and balance the charge. [0003] There is a method in the prior art that allows current to flow through ...
