EPS emergency power supply 12V55AH lithium battery type introduction

EPS emergency power supply 12V55AH lithium battery type introductionEPS topology design is not a simple combination

Some people think: EPS (electronic part) = rectified / charger + inverter + output conversion switch (kit) + control unit and other components can constitute a emergency power supply. Nice, the basic unit of the EPS is composed of the above part, but in order to meet the whole machine reliability (MTBF), how the reliability of each basic unit is * reasonable? The following formula tells us: EPSMTBF = (Rectifier / Charger) MTBF + (inverter) MTBF + (Conversion Switch) MTBF + (Control Unit) MTBF
As can be seen from the above formula, the MTBF of the EPS machine is superimposed by MTBF of most parts, so the overall design of the EPS requires detailed research, analysis, calculating MTBF of most parts, improves the MTBF of weak components, and the overall safety life from EPS The needs of the cycle are configured to configure the safety life cycle of the major components.

A faucet project may develop into an industry and achieve "fusion" of the industry. Beiqi New Energy Industry Qingdao Base has created a new record of intensive intensiveness and development speed: In May 2016, Beiqi New Energy Industry Qingdao Base received a national first new energy vehicle production qualification license; June this year, Beiqi New Energy Industry Qingdao Base passed the technical transformation, production capacity increased from 50,000 to 100,000, and became a industrial base that was prepared from three major advanced technology. At present, the second phase of the Beiqi New Energy Industry, the investment of 4 billion yuan is accelerating, and the main project of the total installation workshop will be completed in November this year. At the end of August 2018, the new energy vehicle production will exceed 200,000, 2020 Reach 300,000.

Introduction to the emergency power supply valve controlled lead-acid battery life

Depth discharge, periodically depth discharge is the main measures for the necessary maintenance of the battery, although the lead-acid battery does not have memory, the battery is maintenance, but it is not to maintain, this is a misunderstanding, depth discharge can increase the activity of the battery. It is a great role in improving the capacity of the battery.

The reason for physical damage, physical damage is generally not known by consumers, and its severity is very terrible. Physical damage is necrosis of polar corrosion, falling off, and breakage caused battery cells, not repaired. This situation is generally liquid There are many types of battery, due to the precursor of charging, the concentration of liquid is increased, and the plates of the top end of the plate do not have a liquid circulation, and the phenomenon of corrosion falling off. If it is not added, it will break, so There are many phenomena, and the dryness will happen.
