URS Products & Testing PVT.LIMITED Batteries Testing ▪ Battery/cell is one of the most critical source of power in most of the electronics products use widely. These play a very important role in product designing and also on product life. These are very useful and in the same way very dangerous if not use as per technical requirements and instruction. +91-9971300904 , [email protected], www.urs-labs.com , F-3, Sector 6, Noida (INDIA) PURPOSE OF A BATTERY ▪ The primary purpose of an battery is to provide a source of electrical power for starting and for electrical demands that exceed generator output. The battery is a voltage stabilizer because it acts as a reservoir where large amounts of current (amperes) can be removed quickly during starting and replaced gradually by the generator during charging. ▪ The battery must be in good (serviceable) condition before the charging system and the cranking system can be tested Battery / Cell Standards ▪ IS 16046-1 ▪ IS 16046-2 ▪ IEC 62133-1 ▪ IEC 62133-2 ▪ UN38.3 ▪ IEC 60896 ▪ IS 16047 ▪ IS 16270 Main Tests ▪ Charging / Discharging Test ▪ Crushing Test ▪ Insulation Resistance Test ▪ External short circuit Test ▪ Continuous charging Test ▪ Free fall Test ▪ Vibration Test ▪ Mechanical Shock Test ▪ Moulded case stress at high ▪ Thermal abuse Test ambient temperature Test ▪ Low-pressure Test ▪ Temperature Cycling Test ▪ Over-charging Test ▪ Incorrect installation Test ▪ Forced discharge Test 6 How Battery Works ▪ A fully charged lead-acid battery has a positive plate of lead dioxide (peroxide) and a negative plate of lead surrounded by a sulphuric acid solution (electrolyte). Difference in potential (voltage) between lead peroxide and lead in acid is approximately 2.1 volts. During Discharging The positive-plate lead dioxide ( PbO 2 ) combines with the SO 4 from the electrolyte and releases its O 2 into the electrolyte, forming H 2 O . The negative plate also combines with the SO 4 from the electrolyte and becomes lead sulphate ( PbSO 4 ). Why Test Battery System There are two main reasons to test a battery: 1- To insure the supported equipment is adequately backed up. 2- To prevent unexpected failures. Why Choose US ▪ URS Lab is NABL Accredited as per ISO 17025 for Electrical (Household, Luminaries, Batteries & Environmental, etc.), Electronics (IT, Audio Video, UPS & EMI/EMC, etc.) and Mechanical (Automotive & Toys) Testing. +91-9971300904 , [email protected], www.urs-labs.com , F-3, Sector 6, Noida (INDIA) Reach Us +91-9971300904 , +91 (120) 4516264, 65 [email protected] www.urs-labs.com F-3, Sector 6, Noida (INDIA)
