Battery management in a device with multiple batteries

Techniques for battery management of a device having multiple batteries are described herein. In one or more implementations, management for increased battery reliability involves assessing a combination of factors that influence a control policy for multiple batteries in a battery system. Based on the assessment, values of control parameters for power management of the battery system are set to reflect a tradeoff between performance and reliability. Then, at least one of battery utilization or charge current distribution is controlled in dependence upon the values that are set. Control of thebattery system can be based in part upon differences in cycle counts for multiple batteries of a battery system for a device, such that cycle counts of the multiple batteries are managed for improvedreliability. 本文中描述了用于具有多个电池的设备的电池管理的技术。在个或多个实现中，用于实现增加的电池可靠性的管理涉及评估影响针对电池系统中的多个电池的控制策略的因素的组合。基于该评估来设置用于电池系统的功率管理的控制参数的值，以反映性能和可靠性之间的折衷。随后，取决于被设置的值来控制电池利用或充电电流分配中的至少者。电池系统的控制可至少部分地基于设备的电池系统中的多个电池的循环计数方面的差异，以使得此多个电池的循环计数被管理以实现改
