  TIP: Power management and battery cell technology for mobile devices

by Ryan Hyde, VP of Engineering, Code Corporation

Our world is now full of mobile devices.  A user can now frequent almost any coffee shop or restaurants and connect to a wireless network.  Being able to set aside the cables and roam freely offer users increased freedom and improved productivity.  To obtain these increases in productivity and freedom, hardware manufacturers must develop and improve power management and hardware solutions.  Power management and design must be considered for each device if it is to operate effectively.  Sometimes a very small configuration change or a seemingly insignificant choice in battery can make the difference between a good and bad user experience. 

Code uses state of the art battery cell technology.  Our latest devices use Lithium ion (LiCoO2) and deliver approximately 2000 mAh storage capacity in a very small package.  It is important to understand the different parameters that distinguish one battery cell from another.  These include, storage capacity, size, cycle life and others. 

  • Storage capacity is critical and is the main parameter used to characterize most batteries.  Let’s suppose that a particular application requires that a device functions throughout an entire 10 hour workday.  If the device pulls power at a rate of 100mA (duty cycle), then over a ten hour period it would need 1000mAh capacity.   
  • Size is another obvious limitation that every industrial designer faces when creating an ergonomically pleasing design.  A battery must be contain a big punch in a small, lightweight package if it is to meet the demands of today’s mobile devices. 
  • Cycle life is a less obvious parameter.  This characteristic of every battery cell eventually becomes important to every consumer but it may be months after the sale.  It becomes important when the device will only function for a few minutes on a fully charged battery. This occurs because the capacity of the battery diminishes with each charge and discharge cycle.  Code batteries are specified and manufactured to retain greater than 70% of their charge capacity after 300 charge and discharge cycles.   This means that a battery charged and discharged every day will last long well into the life of the product.

 One other important parameter that must be considered when using a mobile device is the configuration.  Many users may not realize the significant role that power management play in any electronic device and the effects it has on the user experience and battery life.  Consider a cell phone or a laptop.  Most of these devices are never truly off.  They are only in a low power state waiting for a button press or a wake-up call.  When the user flips the screen or pushes a button the screen is activated.  If the screen was always on, the usable time from one battery charge to another would be significantly shortened.  Like your computer and cell phone, most hardware devices also have levels of sleep.  The first time you place a battery in your cell phone you may be prompted to push a particular button to "turn on” the device.  The time to "wake up” from this state may be significantly longer than the normal "place a call sleep” because the device is booting from a deeper sleep state.

The Code Corporation application team is well trained to understand customer requirements and optimize each unit we sell to take full advantage of the available power.  Generally the application engineering team will consider how our device is being used and what user requirements are necessary.  They then configure the device to take full advantage of available sleep states to optimize every ounce of power available yet meet the requirements set by each user for quick "at the ready” responsiveness.  If you aren’t getting the battery life you think you should then ask us to give you a recommendation regarding your configuration.  Code stands ready to help you succeed in any situation.
