Key factors in power efficiency battery topology

<

The chemical battery discharge curve will largely determine the efficiency you can get from your voltage regulation system, in fact, the power of the supply chain is what you should use.

Lithium-ion batteries must exhibit discharge rates at different temperatures, with actual differences from the initial voltage readings.

If you draw the ability to change the voltage change at home, you will get a peak representative of the discharge capacity (50 open) with the ability to represent the slope of the change in the voltage of each cell, the midpoint. For the lithium-ion battery used in mobile phones, for example, the capacity of the peak flow is about 3.6 volts.

However, the higher the peak, the greater the ability to vary the voltage per unit cell. In other words, a larger capacity change will discharge the battery faster. If you squash the slope (and lower peaks), it may only appear if you have lowered your ability to say 3.6 or 3.5

But to reduce the emission rate, you may increase, for example, the energy of the battery is available to you, 2.8, 2.5, or even 2

Why is it important?

For the system, as a battery voltage for the rechargeable battery status indicator, a small battery discharge error during reading may result in a large error estimation capability. In addition, the temperature of the exhaust gas moving downward at the top of the mountain is lowered.

As a result, system runtime will be greatly reduced at lower temperatures, but there is still a large battery capacity available for operation, albeit at lower voltages.

One solution to this problem is to have an adaptive power topology based on the remaining capacity of the lithium-ion battery with low battery cutoff and to allow the discharge voltage to be lower than the typical 3 - or 3.3V fixed cutoff voltage.

With this scheme, the system can be more predictable for the cell's cycle life and different operating temperatures.

For many consumer electronics products, this solution will allow for more consistent action and longevity of the system in a variety of environments. This is especially useful in systems where the battery is less likely to be removed or replaced periodically as a mobile phone or MP3 player.
