The demand for lithium-ion batteries is growing at an exponential rate. The reason being the rise in the variety and number of IoT-based devices, battery-oriented material handling, and automation equipment. From high-capacity batteries to small smartphones, the high energy density of the cells costs less than other battery technologies. But there are some risks to using Li-ion batteries.
What Are Those?
As there are different requirements for batteries like Li-ion cells for smartphones, 3-12 Li-ion cells for laptops, and hundreds of them for airplanes and cars. They are produced in myriads of forms like a pouch, cylindrical, and prismatic. Cell cases can be soft and hard and electrodes can be stacked and wound. Some of the other problems include-
· Over-voltage
· Overcharge
· Charging outside of the accepted
· Over-discharging
· Fast-charging of the over-discharged cells
· Deep discharging
1. Internal Short Circuits
Overcharging and rough handling can lead to internal short circuits. When the battery becomes stuffed with the ions then it expands which can mechanically stress out the battery. Hence, electron-conducting metallic deposits can be the result.
2. Charging Problems
When the battery is not charged between the temperature +5 to +45 Celsius degrees it could suffer severe damages like cell rupture and runaway. It will end the decomposition and oxidation of the electrolyte.
3. Voltage Limits
Lithium-ion batteries have a high vulnerability to stress when voltage ranges outside the safe voltage. When the battery exceeds this range, then premature aging happens.
Battery Safety Is Must
Nothing to worry about the issues. Solutions come along with the problems. Many battery manufacturers are striving to come up with solutions to the problems commonly faced. Battery Management System is the answer to all the battery-related issues. It acts as a watchtower inside the battery. It can-
· Detect potential threats
· Give protection to the battery from severe damages
· Enhance the reliability, safety, and longevity of the batteries
But what really is BMS (Battery Management System)? It is a controller and a sensor that computes and measures data for ensuring the operation of the battery safely.
It also works to avoid the distribution of power and safeguards the battery pack from any kinds of loss and damage. The critical information and services that BMS provides are-
· Over-cutting protection
· Cell balancing
· SoC and SoH Calculation
· Data analysis and acquisition
· Thermal protection
· Over & Under Voltage Protection
· Avoid thermal runaway with pre-emption
· Warning of potential failure with detection
· Stop thermal runaway with intervention
· Minimize damage with containment
At the vehicle level as well, BMS can help you with offering information about safe driving, preventive protection, secure and rescue, and adaptive protection.
