Description

充电方法、装置及设备 技术领域
本发明实施例涉及电池充电领域，具体而言，涉及一种充电方法、装置及设备。
背景技术
基于智能机发展的趋势，电池依然是薄弱的环节，尽管一些新闻报道出来的超级电池以及新材料的电池，长远看是能解决充电问题，但是短期内商用的可能性不是很大。所以还必须采用传统上的锂/聚合物电池，近期的智能终端标配的电池基本上都在3000mAH,普通的充电方案已经远远不能满足需求，如之前的5V/1A充电，充电时间长达4小时，即使后面使用5V/1.5A充电，单纯的加大电流，造成充电器体积过大，不便于携带，充电时间依然在3小时左右，改善不是很明显。对于智能机在人们生活中的重要地位，充电的时间越短越好。随之而来的是各厂家推出的快速充电，充电的本质上还是加大电流，由1A加大到3A，甚至4A，一定程度上是可以降低充电时间。
但是，随之而来的是大电流造成的种种弊端，比较明显的是发热问题，半导体器件对于温度比较敏感，一般温度高10度，寿命会下降一半。另外大电流给器件选型也带来很多不便，大电流的器件往往过大，会影响ID的设计。故最新的方案都采用双IC(或者多集成电路IC(Integrated Circuit))充电方案，比如充电电流3A，每个IC充电电流只需1.5A，表面上看能解决大电流带来的弊端。
相关技术中，基本上都使用快充方案，而且使用双IC并行充电方案，在电流分配上基本上采用2分的关系，即每个IC分配的电流是相同的。相关技术的并联充电方案，充电电流的分配都是按照固定的比例分配，开机过程中一次性写入，系统运行过程中不能动态的调整，不能实现不同负载的需求，图1是根据本发明相关技术中电路连接的示意图，如图1所示， DC/USB为两种不同的输入，分别是直流和USB供电，Vsys为系统电。这样现存的技术无法动态的实现电流调整，系统稳定性以及电池寿命不能得到更好的体现。
针对相关技术中存在的上述问题，目前尚未发现有效的解决方案。

可选地，在所述IC包括多个充电IC时，调整所述多个IC中一个或多个IC的充电功率占总充电功率的比例包括：判断所述多个充电IC中是否存在第二输出电流大于预设电流的指定充电IC；在判断结果为是时，降低所述指定充电IC的充电功率。
根据本发明的另一个实施例，提供了一种充电装置，包括：检测模块，设置为检测多个集成电路IC在给设备的电池进行充电；调整模块，设置为调整所述多个IC中一个或多个IC的充电功率占总充电功率的比例。
可选地，所述IC包括：集成充电IC，和/或，充电IC。

实施例3
本实施例用于结合具体的场景对本发明的方案进行详细说明，解决不 同场景中的各个具体的问题，如在相关技术的并行充电方案中，有一个是集成的充电IC，这颗IC不仅负责充电，而且负责系统的一部分供电。在系统启动过程以及重负载运行的情况下，集成IC是需要消耗很大的功率，当功率不够的时候，会从另一个IC或者电池抽电流，如果集成的IC提供的电流能满足重负载的话，对于电池寿命以及电路的稳定性都有提高。
本实施例通过根据终端的应用场景以及整机的发热情况，实时的进行并行电流的分配调节，使得重负载以及轻负载下都能满足需求。
图6是根据本发明实施例的电路方块示意图，如图6所示，
本实施例的方案包括电池、主芯片和多个电源管理芯片以及一些单纯充电功能电路(充电IC和集成充电IC)。
可选的，电池可为一节或者多节电池用各种串并联方式组合起来。电池可以包括锂电池、锂聚合物电池以及其他各种可以存储电量的电池。
充电IC：具有单纯充电功能的芯片，可以是一个简单的降压电路或者是一个直流源。
集成充电IC：提供充电功能的同时对外供电，或者集成其他管理类的功能。
电流检测(模块)：对个充电IC充电电流进行检测。其中如果集成IC自身有通讯接口和电流检测功能，则不需要使用电流检测模块。对于独立的单纯模块，无通讯功能和检测功能，需要电流检测模块上报给主芯片。
主芯片：接收设备整体传输过来的有效信息，如各充电IC的工作情况，各模块的功耗需求情况，统筹根据预先设好的优先级进行调整。
可选的，本实施例的应用场景可以但不限于为以下：
1.设备拥有两个充电芯片，对一块电池进行充电，实现快速充电。
2.设备拥有两个以上的充电芯片，对一块电池进行充电，实现快速充电。
3.设备拥有两个以及以上的充电芯片，对一个电池组进行充电。
本实施例的实施场景包括一切多个充电IC或者是多个模块供电的场景状况。
下面对第一种实施案例进行详细说明，对于第二种和第三种类似。
本实施例中使用的两颗充电管芯片，一颗为只进行充电的芯片，设为IC1，另一颗为集成充电功能的管理芯片，集成功能的芯片，同时也会系统供电，设为IC2。原始的电流分配为2分的关系，比如充电器输入电流最大为2A，设为I。
在最初的设置中，两颗芯片的输入电流均为1A，充电电流也相同。后面调试发现，对于IC2来说，1A的输入电流不满足系统的需求，最后调整为1.5A，IC1调整为0.5A。但这写设置都是开机时刻一次性设置完成，在系统运行过程中无法进行动态调整。
设IC1的输出电流采样于R1，IC2输出电流采样于电阻R2，在输入电流满足需求的情况下，流过R1和R2的电流为正值，分别设为I1、I2。即R1*I1＝U1,R2*I2＝U2。U1、U2均为正值。如果两者均为正值，则系统供电正常，如果发现其中U2小于0，进行调整对应的I2，使用增量为0.1A(可以任意)即ΔI。优先调整I1电流大大小，使用I1(new)＝I1-N*ΔI,调节I2(new)＝I2+N*ΔI一直到U2大于0，其中，N为1.2.3…。
如果发现U2一直为正，如果比较接近U2max(预设阈值)。则使用与上面相反的方法，调整其电流大小，设IC1的输出电流采样于R1，IC2输出电流采样于电阻R2，在输入电流满足需求的情况下，流过R1和R2的电流为正值，分别设为I1、I2。即R1*I1＝U1,R2*I2＝U2。U1、U2均为正值。如果两者均为正值，则系统供电正常，但是如果发现其中U2大于0，并且超过了U2max，进行调整对应的I2，使用增量为0.1A(可以任意)即ΔI。优先调整I1电流大大小，使用I1(new)＝I1+N*ΔI,调节I2(new)＝I2-N*ΔI一直到U2小于U2max，其中，N为1.2.3…。
对于上述三种实施案例，均可以使用其变形技术方案进行实现。
通过本实施例，与现有技术相比，可以根据设备应用场景合理的分配 充电电流和其他模块的电流，更大程度的有利于系统温度和提高电池寿命。
图7是根据本发明实施例的电流调整的基本流程图，如图7所示，包括：
S71：各相关模块上报需求信息，如电流、电量、温度以及功耗情况；
S72：主芯片根据上报过来的信息，对其所辖芯片进行整体调控；
S73：根据信息去调整其中一个芯片的电流情况，然后再去判断结果是否生效以及是否达到预期结果，如果结果满足，则继续进入等待，如果结果不满足，则调整与其相关联的模块；
S74：若调整其相关的模块依然未达到其效果，则说明第一步调整力度不够，加大调整力度，依然进行效果判断。
本实施例在设备具有多个充电芯片的时候，根据应用场景合理的安排负载电流的大小。在设备具有多个电池组的时候，能够合理的根据设备的整体环境(整机功耗。发热情况)合理的分配电流。
