Benefits of using Lithium-Ion batteries have made them the best choice for medical equipments like portable ECG Machines. Operating the machine on a battery can help rule out glitches that could arise in the event of power fluctuation. bqSWITCHER which is a Lithium-Ion charge management IC is used in the charger design circuit. A Lithium-Ion battery of two cells is selected. We have designed a jig to charge 12 Lithium-Ion batteries to 8.4V each. By using this battery which is charged to 8.4V the portable ECG machines can complete 500 three-channel or 250 one-channel ECGs. This paper introduces high speed charging of battery for fast assembly of portable ECG machines, which in turn will increase the production of portable ECG machines.
