Battery Charger Functioning

Conventional Battery Charger

Charging Scheme

Problem to be Addressed

• Each battery has different voltage level after it usage
• The voltage shared by different cells is different while current is same
• Efficiency and self life of battery diminished due to overcharging
• Battery get exploded due to over charging
• Sometime due to one faulty battery whole set of battery unable to charge properly
• Reduce the wastage of electricity

Design of low cost add-on module to existing battery charger

Socio Economic Impact

• Protection from any accident due to overcharge
• Increasing the self life of the Battery
• Enhancing the efficiency of Charging
• Economical uplifting of the Supplier
• Beneficial for other battery charging shops- Car Battery shop etc.
• Technology can be given to charger designer

​

​

Objective

• Design and development of low cost battery charging level management system
• Estimation of average battery charging time
• User interactions for system validation

Methodology

Conventional Charger
