The difference between power lithium battery and capacity lithium battery

Dynamic lithium ion batteries need more considering reliability and consistency. After all, It need to be used for a long period of time (at least 5 ~ 10 years) under severe environment (low temperature in winter, summer blazing sun, rain and snow). A large number of batteries are connected in series and parallel with group. Considering the reliability and consistency, it is assumed that a car uses only 1000 power battery. Ideally, manufacturers hope that model cars don't have the problem under the scale of 100000. It is the ideal requirements on power battery problems (safety, storage, circulation, etc.) It is more likely to be below the one over one hundred million (for the most high-end consumer battery, of course, Apple also has this level requirement to supplier).Considering the reliability, more general design class batteries which power the redundancy, use thicker diaphragm, foil and shell, so the energy density is probably half consumer batteries.

Consumer lithium ion battery don't need long time reliability (circulation also need not do so well, because it would be in a year or two anyway), generally do not need to match group used alone, so no too big to consistency requirements, but because of consumer's mobile phone, pad space is limited and very precious, so consumer lithium ion battery for strict size, capacity and energy density is very demanding.

For safety, more external power battery protection circuit, heat dissipation layout and so on, of course also faces more harsh conditions (higher external voltage, the bigger current, more complex external environment), consumer battery less protection, want to be in a higher energy density by battery materials and design on the basis of resistance to live of the security risks.

Personally, I think the high-end consumer battery USES the most advanced technologies and materials, and power battery is the need for more advanced process control and consistency control and quality management.

1. Capacity is not the same, the power of large mobile phones and other electronic products capacity is small,

2. The cycle life of power will be high

3. The temperature control point for the power will be a protection of the temperature of the battery pack.

Power lithium battery: What is the difference between type and capacity lithium battery?

Are many types of lithium batteries, like power type lithium battery type and capacity lithium battery, so what is the difference between this two kinds of lithium battery? May be a lot of people are not very clear

What is the difference between power lithium battery and lithium battery capacity.

1, the voltage in different sizes

In the battery industry, the increase of voltage, the corresponding output voltage also increases, so as to make the dynamic type lithium battery pack can meet some of the high power devices; And parallel way to directly affect the result, make the whole battery current increases, the capacity is affected by the output current, so the parallel direct action is making lithium battery capacity increases, the connection of the capacity of the battery pack in this way tend to be larger, known as the capacity of the lithium-ion battery pack.

2, the application of different products

Some large equipment need voltage value is higher, because of the low power battery doesn't work, so be about to choose type power lithium-ion battery pack. We usually used in the electric bicycle, for example, it is required by the voltage value tend to be 48 v, relative to some things in our life, 48 v is not small. So we must use power type lithium battery pack to ensure electric bicycle. And we usually go to a few large supermarkets or shopping malls, some marker light and standby power, because of these devices and power consumption is not very big, so commonly used type capacity lithium battery pack, between the two is different on the application of the product.

3, internal resistance of different

Power type lithium battery internal resistance to specific storage type of lithium battery is small, in 18650, for example, 3 discharge of good manufacturer with PDC commonly, internal resistance around 40;5 discharge generally don't take the PDC resistance around 20.
