Information @ a Glance

General

  • A battery pack is a set of any number of (preferably) identical batteries or individual battery cells.
  • Components of battery packs include the individual batteries or cells, and the interconnects which provide electrical conductivity between them.
  • Packs are often simpler for end users to repair or tamper with than a sealed non-serviceable battery or cell.
  • It is common for battery pack vendors to use cells from a variety of manufacturers.
  • It is a Portable power packs that snap into various cordless tools, ranging in voltages from 3.6V to 36V.

Operating Process

  • Cells and batteries are tested at multiple stages of the development and productions process: cells are qualified for a particular battery design; then each battery is tested after being assembled and, prior to shipment, is retested in-system.
  • Customized batteries meet size, weight, and performance needs, and can include safety features, and tailored functions such as runtime indicators, authentication functions, and data logging, if the user chooses.
  • A battery's recoverable capacity decreases slightly depending on the depth of the discharge. As the battery cycles, it can no longer deliver 100% of its rated capacity.
  • The most common battery type used in today’s electronic products are Lithium “button cell” batteries.
  • Batteries or battery packs must show no signs of leakage or corrosion.

Applications

  • Smart battery systems, or battery systems that can communicate back to the host, are the preferred choice in mission-critical applications, as it has the ability to monitor its status, accurately predict its remaining run time, and communicate its operational status to the host device.
  • Lithium-Ion batteries, with several critical advantages over their traditional competitors by being much lower weight, higher efficiency, and less leakage, are playing more important role in industrial applications.
  • Lithium batteries are often preferred for high current-pulse marine applications due to their inherent long life and high energy density.
  • Every notebook PC platform has its own battery pack design to meet the specific platform design requirements. This approach incurs redundant time, effort, and expense to the platform design and integration.

Technology

  • The battery pack is capable of supporting future battery technologies like Prismatic cells.
  • The most common technique used today for battery capacity monitoring is coulomb counting, tracking the current into and out of the battery.
  • A novel divide and conquer technique is developed to efficiently apply pulse-charging method in high-capacity battery pack applications.
  • “Galvanostatic” technique involves driving a constant current into the battery. This method can be used to charge the battery quickly and is simple to implement.

Market

  • A Company will manufacture smart battery packs on new production lines at the Company's manufacturing facility in Korea.
    The worldwide battery pack market is highly fragmented, It is believed that substantial opportunity exists for a well-funded operation done by one company.
  • World Battery & Fuel Cell Chemicals and Materials market is projected to maintain a strong CAGR of 6.7% over 2001-2010 to reach US$21.2 billion by 2010.
  • Japan, with a share estimated at 29.04% in 2006, constitutes the largest market, while Asia-Pacific, with a CAGR of 9.39% over 2001-2010, represents the fastest growing market for battery & fuel cell chemicals and materials.
  • Many battery manufacturers are turning towards high performance rechargeable batteries and adapting them according to the demand. As the market for these batteries is growing, the demand for chemicals and materials used in the production of these batteries is also growing by leaps and bounds.
