Battery Fuel Gauge


The fuel gauge is an advanced warning system for the device’s batteries.It can report the data of each cell voltage,total battery pack voltage, 

battery temperature, battery SOC,battery cycle,and also can communicate with the computer through the SmBus design,CanBus design,etc

 


In battery charging and conditioning systems, discharge circuits may be used to completely discharge a battery before beginning a charging cycle. 
In battery calibration systems, discharge circuits may be used to determine the characteristics of batteries. For battery types such as lithium ion (Li-ion),
determining the characteristics of the battery under load conditions may assist in determining battery condition as it ages. Additionally, calibration systems 
produce information that allows predicting performance of the battery over its service life.
 
E&J has a patented design for a discharge circuit that addresses the challenges of battery calibration in environments where consistent power is often unavailable, such as in military vehicles and ambulances, creating a fresh approach to the issue of controls attached to the interfaces of battery chargers.
Fuel gauging is a critical function of lithium ion battery pack design. Proper, accurate fuel gauging not only provides a clear input to the end-user regarding the available Relative State of Charge (RoC) but can also extend the cell cycle life in conjunction with methods to control depth of discharge and charge. In addition, advanced fuel gauging and data acquisition circuits can determine the battery characteristics under load and assist in determining the overall impact of aging.
 
In order to develop and implement a fuel gauge properly, accurate calibration methods must be employed. E&J has a patented design for a discharge 
circuit that addressed the challenges of battery calibration in environments where consistent power is often unavailable, such as in military vehicles and ambulances.


E&J also has the ability to develop a customized fuel gauge that can take into account specific customers needs and facilitate integrated 
authentication protocols, App with smartphone, Battery Fuel Gauge with Bluetooth function,etc..
