Lithium batteries have been extensively employed in electric vehicles and energy storage power stations due of their high power and energy density, long service life, and low associated pollution , order to fulfill the power requirements of electric vehicles, multiple battery cells need to be connected, in series and parallel, to form a battery pack .
The BMS will also control the recharging of the battery by redirecting the recovered energy (i.e., from regenerative braking) back into the battery pack (typically composed of a number of battery modules, each composed of a number of cells).; Battery thermal management systems can be either passive or active, and the cooling medium can either be air, liquid, or some form of

Moreover, in conventional Battery Management Systems (BMS), the cell balancing, charging strategy and thermal regulation are treated separately at the expense of faster cell deterioration. Hence, this
The term battery is often used to describe both a single battery cell and a multi-cell battery pack. Battery cells are defined as the smallest individual electrochemical unit, and deliver a voltage dependent on a specific cell chemistry. Battery packs are assembled from groups of cells organized into modules in series and parallel configurations.

Protection boards for lithium batteries offer monitoring protection. Low-voltage lithium batteries require a protection board. When using high-voltage lithium batteries, a battery management system (BMS) is typically chosen since these systems contain more functions for monitoring the state of the battery pack.
We suggest that you should never use lithium ion/polymer batteries without protection cells. Without the protection, a slight mistake in their use could destroy the battery and they have a much higher risk of exploding or catching on fire. Text editor powered by tinymce. If you want to take your project portable you'll need a battery pack!
You can also obtain custom-built protection boards with your custom battery packs. This arrangement is ideal since the battery manufacturer will have a greater understanding of the protection needs of the custom pack that they design for the customer. So, the protection board would cater to these design requirements.
The battery cells can now receive a charge from a charger. Some devices may pull out too much of a charge in too fast of a short time span. To protect the battery cell and MOS tube, the protection board enacts discharge protection to the cell, turning off the pins and disconnecting the switch tubes.
It will protect Lithium battery pack from overcharging, over-discharging and over-drain, therefore it is the must to have to avoid Lithium battery pack from explosion, fire and damage. For low voltage lithium battery packs (<20 cells), you shall choose PCM with equilibrium function to keep each cell in balance and good service life.
Therefore the pack current, cell temperature, and each cell voltage should be monitored timely in case of some unusual situations. The battery pack must be protected against all these situations. Good measurement accuracy is always required, especially the cell voltage, pack current, and cell temperature.
