Technology OverviewThe evolution of battery technologies has had a great affect on' people's life styles.In general, we classify batteries by types, capacity ranges, applications etc. Our technologies serve the following applications: 1) Backup batteries for mission critical systems; 2) High power batteries for electric vehicles, locomotives and marine applications. 3) Start-up batteries for emergency power generators. Almost all of today's portable devices come with batteries. ( cell phones, iPods, laptops, video cameras etc.) Most of them have fuel gauges, which while often not accurate, indicate the remaining energy in the battery. As you charge the battery, the fuel gauge goes up until indicating fully charged. As the discharge goes on, the remaining hour or percentage is estimated by taking account of capacity, current and voltage etc. (BATTERYDAQ PRODUCTS DO NOT SERVE THIS MARKET.) With regard to backup batteries, they are usually at a fully charged state. In the event of a power loss, the batteries supply the energy to support the continuous running of critical systems. But just like an exhausted battery pack in a laptop,which while still showing 100% full at charge condition, the backup battery may last for a very short time after when called upon to supply power. The whole set of functional looking batteries may disappoint you when you need them the most. One compromised battery may lead to the failure of the whole battery system. These types of unexpected failures are often expensive. (Click to see some extreme examples.) Monitoring a battery's state-of-health will help to weed out the compromised battery at an early stage. We have invented and improved the core technology - online internal resistance measurement. Combined with our many other proprietary technologies and expertise, our products provide comprehensive battery monitoring and management. The main measurement parameters are:
Based on the above measurements, the state-of-health is reliably estimated by data trending.
Our IR online measurement technology provides unsurpassed resolution and accuracy when compared to other online technologies available on the market. No need for discharge. * Ref to IEEE Std. 1491-2005 IEEE Guide for Selection and Use of Battery Monitoring Equipment in Stationary Application Volume, Issue, 2005 Page(s):0_1 - 33 3. Definitions 3.3 internal ohmic value: Any value of resistance, conductance, or impedance derived from the relationships between changes in voltages and currents in a stationary battery under various conditions and used as an indicator of a battery's state of health. |
