本公开实施例提供的充电电路，在第一充电模式下通过第一充电支路210向并联的第一电池110和第二电池120供电，在第二模式下通过第二充电支路220向并联的的第一电池110和第二电池120供电，通过第一充电模式和第二充电模式各自使用不同的充电支路，从而能够减少第一充电支路210上的器件，从而能够减小第一充电模式下第一充电支路210上的电阻值，进而减少充电时的发热量，降低了电子设备的安全隐患。The charging circuit provided by the embodiment of the present disclosure supplies power to the first battery 110 and the second battery 120 connected in parallel through the first charging branch 210 in the first charging mode, and supplies power to the first battery 110 and the second battery 120 connected in parallel through the second charging branch 220 in the second mode. By using different charging branches in the first charging mode and the second charging mode, the number of devices on the first charging branch 210 can be reduced, thereby reducing the resistance value of the first charging branch 210 in the first charging mode, thereby reducing the heat generated during charging, and reducing the safety hazard of the electronic equipment.
进一步的，如图5所示，本公开实施例提供的充电电路还可以包括第一电量计130、第二电量计140和双向限流模块150。第一电量计130设于第一电池110和第一节点P之间，第一电量计130用于检测第一电池110的电压和电流。第二电量计140设于第二电池120和第一节点P之间，第二电量计140用于检测第二电池120的电压和电流。双向限流模块150的第一端连接第一节点P，双向限流模块150的第二端连接第二电池120的第一电极。Further, as shown in FIG5 , the charging circuit provided in the embodiment of the present disclosure may further include a first fuel gauge 130, a second fuel gauge 140 and a bidirectional current limiting module 150.

下面将对本公开实施例提供的充电电路的各部分进行详细说明：The following is a detailed description of each part of the charging circuit provided in the embodiment of the present disclosure:
在本公开实施例中，第一电池110的正极连接第二电池120的正极(二者连接于第一节点P)，第一电池110的负极连接第二电池120的负极(二者接地)。第一充电支路210可以是快充支路，第二充电支路220可以是预充电以及普通充电支路。第一充电支路210的充电功率大于第二充电支路220的充电功率，示例的，第一充电支路210的充电电流大于第二充电支路220的充电电流。预充电是指在锂离子电池等电池充电过程中，通常需要首先对电子设备进行预充电，避免直接进入快充模式影响电池使用寿命或者破坏电池。In the disclosed embodiment, the positive electrode of the first battery 110 is connected to the positive electrode of the second battery 120 (the two are connected to the first node P), and the negative electrode of the first battery 110 is connected to the negative electrode of the second battery 120 (the two are grounded). The first charging branch 210 can be a fast charging branch, and the second charging branch 220 can be a pre-charging and ordinary charging branch. The charging power of the first charging branch 210 is greater than the charging power of the second charging branch 220. For example, the charging current of the first charging branch 210 is greater than the charging current of the second charging branch 220. Pre-charging means that during the charging process of batteries such as lithium-ion batteries, it is usually necessary to pre-charge the electronic device first to avoid directly entering the fast charging mode to affect the battery life or damage the battery.
如图2所示，第一充电支路210可以包括直充开关211和电压转换模块212，直充开关211的第一端连接充电接口310，直充开关211的第二端连接电压转换模块212，直充开关211响应直充控制信号而导通。电压转换模块212的第二端连接第一节点P，电压转换模块212用于调整直充开关211输出的信号的电压。As shown in FIG2 , the first charging branch 210 may include a direct charging switch 211 and a voltage conversion module 212. The first end of the direct charging switch 211 is connected to the charging interface 310, and the second end of the direct charging switch 211 is connected to the voltage conversion module 212. The direct charging switch 211 is turned on in response to a direct charging control signal. The second end of the voltage conversion module 212 is connected to the first node P, and the voltage conversion module 212 is used to adjust the voltage of the signal output by the direct charging switch 211.
其中，直充控制信号可以包括第一控制信号，直充开关211可以是MOS管、电磁触点式开关或者继电器开关等。直充开关211可以包括第一端(输入端)、第二端(输出端)和控制端，直充开关211的第一端连接充电接口310，直充开关211的第二端连接第一节点P，直充开关211的控制端接收第一模式控制信号，直充开关211响应第一模式控制信号而导通以将电源信号传输至电压转换模块212的第一端。The direct charging control signal may include a first control signal, and the direct charging switch 211 may be a MOS tube, an electromagnetic contact switch or a relay switch, etc. The direct charging switch 211 may include a first end (input end), a second end (output end) and a control end. The first end of the direct charging switch 211 is connected to the charging interface 310, the second end of the direct charging switch 211 is connected to the first node P, and the control end of the direct charging switch 211 receives a first mode control signal. The direct charging switch 211 is turned on in response to the first mode control signal to transmit the power signal to the first end of the voltage conversion module 212.
示例的，当直充开关211为MOS管时，MOS管的第一端可以是源极，MOS管的第二端可以是漏极，MOS管的控制端为栅极。或者MOS管的第一端可以是漏极，MOS管的第二端可以是源极，本公开实施例对此不做具体限定。直充开关211可以是N型MOS管或者P型MOS管，当直充开关211为N型MOS管时，第一模式控制信号可以是高电平信号；当直充开关211为P型MOS管时，第一模式控制信号可以是低电平信号。For example, when the direct charging switch 211 is a MOS tube, the first end of the MOS tube may be a source, the second end of the MOS tube may be a drain, and the control end of the MOS tube may be a gate. Alternatively, the first end of the MOS tube may be a drain, and the second end of the MOS tube may be a source, which is not specifically limited in the embodiments of the present disclosure. The direct charging switch 211 may be an N-type MOS tube or a P-type MOS tube. When the direct charging switch 211 is an N-type MOS tube, the first mode control signal may be a high-level signal; when the direct charging switch 211 is a P-type MOS tube, the first mode control signal may be a low-level signal.
如图3所示，电压转换模块212可以包括电荷泵2121，直充开关211的第一端连接充电接口310，直充开关211的第二端连接电荷泵2121的第一端，直充开关211响应直充控制信号而导通。电荷泵2121的第一端连接直充开关211的第一端，电荷泵2121的第二端连接第一节点P。当然在实际应用中，电压转换模块也可以包括其他DC-DC电路本公开实施例并不以此为限。As shown in FIG3 , the voltage conversion module 212 may include a charge pump 2121, a first end of the direct charge switch 211 is connected to the charging interface 310, a second end of the direct charge switch 211 is connected to a first end of the charge pump 2121, and the direct charge switch 211 is turned on in response to a direct charge control signal. The first end of the charge pump 2121 is connected to a first end of the direct charge switch 211, and the second end of the charge pump 2121 is connected to a first node P. Of course, in practical applications, the voltage conversion module may also include other DC-DC circuits, and the embodiments of the present disclosure are not limited thereto.
电荷泵2121的第一端(输入端)连接直充开关211的第一端，电荷泵2121的第二端(输出端)连接第一节点P。电荷泵2121用于调节第一充电支路210的充电电流和充电电压，比如，电荷泵2121可以用于降低电源信号的电压并提高第一充电支路210的充电电流，电荷泵2121可以是2:1的电荷泵2121，也即是电荷泵2121能够使第一充电支路210的电压减半电流加倍。The first end (input end) of the charge pump 2121 is connected to the first end of the direct charging switch 211, and the second end (output end) of the charge pump 2121 is connected to the first node P. The charge pump 2121 is used to adjust the charging current and charging voltage of the first charging branch 210. For example, the charge pump 2121 can be used to reduce the voltage of the power signal and increase the charging current of the first charging branch 210. The charge pump 2121 can be a 2:1 charge pump 2121, that is, the charge pump 2121 can halve the voltage and double the current of the first charging branch 210.
第一充电支路210导通时，电池阻抗比被配置和电池容量比一致。电池阻抗比为第一电池110的充电通路的阻抗和第二电池120的充电通路的阻抗比第一电池110。电池的容量比为第一电池110容量和第二电池120容量的比值。当电池阻抗比和电池容量比的差值在预设范围值内时，认为电池阻抗比和电池容量比一致。通过电池阻抗比和电池容量比一致能够减少充电过程中的发热量，并且减少电池放电过程中的能量的损耗。When the first charging branch 210 is turned on, the battery impedance ratio is configured to be consistent with the battery capacity ratio. The battery impedance ratio is the ratio of the impedance of the charging path of the first battery 110 to the impedance of the charging path of the second battery 120. The battery capacity ratio is the ratio of the capacity of the first battery 110 to the capacity of the second battery 120. When the difference between the battery impedance ratio and the battery capacity ratio is within a preset range, the battery impedance ratio and the battery capacity ratio are considered to be consistent. By making the battery impedance ratio and the battery capacity ratio consistent, the heat generated during the charging process can be reduced, and the energy loss during the battery discharge process can be reduced.
第二充电支路220包括电源管理模块222和过压保护模块221，过压保护模块221的第一端(输入端)连接充电接口310，过压保护模块221的第二端(输出端)连接电源管理模块222的第一端(输入端)，电源管理模块222的第二端(输出端)连接第一节点P，电源管理模块222用于将电源信号转换为第二充电信号传输至第一节点P。The second charging branch 220 includes a power management module 222 and an overvoltage protection module 221. The first end (input end) of the overvoltage protection module 221 is connected to the charging interface 310, the second end (output end) of the overvoltage protection module 221 is connected to the first end (input end) of the power management module 222, and the second end (output end) of the power management module 222 is connected to the first node P. The power management module 222 is used to convert the power signal into a second charging signal and transmit it to the first node P.
其中，过压保护模块221(比如，OVP 2211，Overvoltage Protection)用于为下游电路(比如电源管理模块222)提供保护，避免传输至电源管理模块222等下游电路的电压过高，导致高电压的损坏电路器件。过压保护模块221监测充电接口310接收的的直流电压，并且根据直流电压的电压值判断是否需要过压保护。当充电接口310接收到的直流电压值大于预设阈值时，对第二充电支路220进行过压保护。Among them, the overvoltage protection module 221 (for example, OVP 2211, Overvoltage Protection) is used to provide protection for downstream circuits (such as the power management module 222) to prevent the voltage transmitted to the downstream circuits such as the power management module 222 from being too high, causing high voltage to damage circuit components. The overvoltage protection module 221 monitors the DC voltage received by the charging interface 310, and determines whether overvoltage protection is required based on the voltage value of the DC voltage. When the DC voltage value received by the charging interface 310 is greater than the preset threshold, the second charging branch 220 is overvoltage protected.
示例的，可以通过撬棍钳位电路或串联开关对第二充电支路220进行过压保护。在撬棍钳位电路中设置有保险丝，当电源信号的电压大于预设阈值时，可以通过熔断保险丝保护电路。或者可以在第二充电支路220上设置串联保护开关，当当电源信号的电压大于预设阈值时，串联的保护开关关断。For example, the second charging branch 220 can be protected from overvoltage by a crowbar clamp circuit or a series switch. A fuse is provided in the crowbar clamp circuit, and when the voltage of the power signal is greater than a preset threshold, the circuit can be protected by blowing the fuse. Alternatively, a series protection switch can be provided on the second charging branch 220, and when the voltage of the power signal is greater than a preset threshold, the series protection switch is turned off.
电源管理模块222(比如，PMIC 2221)用于对第一电池110和第二电池120的充放电进行管理，电源管理模块222中可以包括开关电路和管理电路。开关电路可以包括普充开关，普充开关可以响应第二模式控制信号而导通，使第一电池110和第二电池120可以通过第二充电支路220进行充电。管理电路用于控制第二充电支路220的充电电流和充电电压。The power management module 222 (e.g., PMIC 2221) is used to manage the charging and discharging of the first battery 110 and the second battery 120. The power management module 222 may include a switch circuit and a management circuit. The switch circuit may include a general charging switch, which may be turned on in response to the second mode control signal, so that the first battery 110 and the second battery 120 can be charged through the second charging branch 220. The management circuit is used to control the charging current and charging voltage of the second charging branch 220.
电源管理模块222还包括第三端(放电端SK)，在电池充电过程中以及放电过程中可以通过电源管理模块222的第三端向电子设备内的用电器件(比如显示装置、处理器、存储器、摄像模组和音频模组等)供电。在充电过程中可以由充电接口310输入的电源信号通过电源管理模块222的第三端向电子设备内的用电器件供电；也可以是通过第一电池110和/或第二电池120通过电源管理模块222的第三端向电子设备内的用电器件供电；还可以是通过充电接口310输入的电源信号以及第一电池110和/或第二电池120结合向电子设备内的用电器件供电，本公开实施例对此不做具体限定。The power management module 222 also includes a third terminal (discharge terminal SK), and power can be supplied to the electrical devices (such as display device, processor, memory, camera module and audio module, etc.) in the electronic device through the third terminal of the power management module 222 during the battery charging process and the discharging process. During the charging process, the power signal input by the charging interface 310 can be used to supply power to the electrical devices in the electronic device through the third terminal of the power management module 222; the first battery 110 and/or the second battery 120 can also be used to supply power to the electrical devices in the electronic device through the third terminal of the power management module 222; or the power signal input by the charging interface 310 and the first battery 110 and/or the second battery 120 can be used to supply power to the electrical devices in the electronic device in combination, and the embodiments of the present disclosure do not specifically limit this.

The management circuit may be connected to a processor in the electronic device. The voltage regulation circuit and the current regulation circuit respond to the charge and discharge management signal sent by the processor to control the charging signal or the discharging signal output by the second charging branch 220.
第一控制信号可以是电子设备的处理器提供或者是电源管理模块222提供。当电子设备检测到充电接口310连接的是第一模式适配器(快充适配器)时，电子设备的处理器提供或者是电源管理模块22向直充开关211提供第一控制信号，第一充电支路210导通，电子设备进行第一模式充电。第二制信号可以是电子设备的处理器提供或者是电源管理模块222提供。当电子设备检测到充电接口310连接的是第二模式适配器(普充适配器)时，电子设备的处理器提供或者是电源管理模块22向开关电路提供第二控制信号，第二充电支路220导通，电子设备进行第二模式充电。当然当处于预充模式下时，充电接口310连接第一模式适配器时，直充开关211关断，电子设备仍以第二模式充电。The first control signal may be provided by the processor of the electronic device or by the power management module 222. When the electronic device detects that the charging interface 310 is connected to the first mode adapter (fast charging adapter), the processor of the electronic device provides or the power management module 22 provides the first control signal to the direct charging switch 211, the first charging branch 210 is turned on, and the electronic device performs first mode charging. The second control signal may be provided by the processor of the electronic device or by the power management module 222. When the electronic device detects that the charging interface 310 is connected to the second mode adapter (general charging adapter), the processor of the electronic device provides or the power management module 22 provides the second control signal to the switch circuit, the second charging branch 220 is turned on, and the electronic device performs second mode charging.
