Custom lithium ion batteries for electric cars and the need for a BMS

A battery management system or BMS is included in most battery packs to assess the reliability and functionality of the battery. When considering lithium ion batteries, most people may wonder how necessary the BMS really is and whether it is really needed.

Lithium-ion batteries don’t really need the management system to function or operate. It is quite easy to connect several battery cells within a series and create a pack without including a battery management system. It is possible to power things and charge such batteries without any incidence. However, in terms of lifespan and safety, a BMS proves to be very important and useful.

Battery management
Lithium battery management systems are meant to make sure that the cells can operate within safe limits. The system needs to take action if any cell within the pack starts moving outside the set limits.

The kind of action taken by the BMS usually depends on its design and how it works. In most cases, the load is disconnected when the voltage is too low. It also involves disconnecting chargers should the voltage be heading towards too high.

A BMS also checks cell voltage individually for all the cells in a pack. If any of the cells happen to be a bit higher than others, then it is corrected. In this way, the cells do not get too low or dangerously high voltages that could cause issues. The high voltages are what cause battery fires. The temperature of batteries has to be monitored at all times. It is not wise to rely on a charger or using the battery as instructed. Things could go wrong, and when the BMS is intact, then a lot of bad things are prevented.

BMS functionality
Being aware of the functionality of BMS is important. There are so many interpretations of BMS which determine the kind of functions that are performed. Most of them rely on the intervention of users. It is important to find a good manufacturer who uses the right system in the right battery pack.

Lead-acid batteries don’t need a battery management system. This is because the likelihood of the lead-acid battery bursting into flames is very low. This means it is a lot safer to charge and discharge this type of battery. This is due to the ingredients used. The reason is also how cells usually behave when fully charged. The lead-acid batteries are often made of cells that are within a series. When one cell is more charged than others and reaches full charger faster than others, the current is passed very simply through the cell but remains within the reasonable voltage limit. This is self-equalizing.

For lithium-ion batteries, the behavior is different. After a full charge, the voltage can rise to very dangerous levels. This is what there is a need to monitor and control, the voltage within a pack. The BMS is, therefore, an important part of this type of battery.

JB Battery creates some of the most reliable battery options available in the market today.
