Intelligent lithium battery - ECG intelligent lithium battery applications:
一, Electrocardiograph machine introduced
1, the use of digital isolation technology, so that the temperature of the device to minimize the effects of drift and time drift, and to ensure the high adaptability of the instrument to the environment.
2, the use of digital signal processing, processor ECG drift suppression, AC filter, EMG filtering and heart rate detection, treatment, to ensure the authenticity and reliability of the signal processing.
3, with automatic adjustment of baseline drift can effectively suppress baseline drift due to interference caused to optimize printing position to obtain high-quality ECG spectrum.
4, with automatic measurement of ECG parameters, automatic analysis function, reducing the burden on clinicians.
5, precision hot phalanx recording ECG waveform, waveform tracings clear and accurate, rich text notes, complete various markers for clinical diagnosis and research.
6, with a width of 63mm high-speed thermal recording paper tracings ECG, 12 lead simultaneous acquisition and real-time recording of three, clinical examination ECG aging high, effective and economical rhythm leads freely choose

The ECG machine intelligent lithium battery protection circuit program are as follows:
A smart electricity meter protection board (PCM): SBS intelligent battery management system, advanced power calculation principle accurately calculate the battery from time to time in power, from time to time through the SMBUS Charge Information reported to the host cell, while the rechargeable smart protection function of the battery pack (generally refers to lithium batteries), due to the chemical characteristics of the lithium battery, it is necessary to provide overcharge, over discharge, short circuit, overcurrent and overtemperature protection features, to avoid causing the combustion, explosion hazard.
2, LED power display board: LED battery indicator light ratio of 20% of the electricity, the smart electricity meter protection board always calculate the battery capacity is visually displayed so efficient and intuitive convenience of customers.
3, over-current protection chip (PTC): mainly designed for secondary protection. PTC resettable fuse overcurrent protection, to restore dual function automatically. PTC battery products can prevent the occurrence of high-current battery of high-temperature discharge and unsafe.
