Technologies for rechargeable batteries and chargers



SMBus protocol used in BMS design

[Issued date: May 2014]
The System Management Bus (SMBus) is a two-wire interface through which various system component chips can communicate with each other and with the rest of the system. It is based on the principles of operation of I2C*.With System Management Bus, a device can provide manufacturer information, tell the system what its model/part number is, save its state for a suspend event, report different types of errors, accept control parameters, and return its status...

How to design a battery monitor or battery indicator

[Issued date: Arpil 2012]
How to monitor your battery remain capacity, in other words, how long does my battery keep working normally? There are three algorithms to measure the remain of your battery: “Voltage-Capacity-Curve Lookup”, “Current-Accumulating” and “Impedance-Track” method.......

How to design a smart charger for your battery-pack

[Issued date: Arpil 2012]
Overview of Battery-Charging Techniques Four rechargeable battery chemistries are in practical use today: Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), Gelled Lead-Acid (PbSO4), and Lithium-Ion (Li+). The trade-offs to be made among these chemistries are beyond the scope of this article, but the References section provides access to such information. Caution: consult the battery manufacturer for specific recommendations......
   

Battery and Chargers Essentials

[Issued date: Arpil 2012]
The continually expanding market for portable equipment is creating an increasing demand for improved battery performance and operating life. To meet these criteria the capacity and capability of rechargeable cells has steadily increased, from the introduction of commercial nickel cadmium (NiCd) and sealed lead acid (SLA) batteries in the 1960's to the more recent introduction of nickel metal hydride (NiMH) and lithium ion (Li-I, or Li+) technologies.......
   

Battery charger circuits

[Issued date: Arpil 2012]
Here we provided several schematic drawings of battery charger circuit. These circuits covered 5W~200W NiCd, NIMH, Lead-Acid, and Li-Ion/Polymer ,LiFePo4 battery packs. We hope chargers circuits files can help our users to select correct chargers also can help them to get a good understanding about our products....
