ABOUT
Battery Management System is generally a protective system for monitoring the battery ( most often used for Li-ion batteries), and to ensure the safe operation of the battery under various environmental conditions.
BMS :
The BMS is mostly employed along with Lithium-ion batteries as Li-ion batteries have an immense applications in a vast variety of areas including automobiles such as e-Vehicles. This system controls the recharging the batteries of e-Vehicles by redirecting the energy that has been recovered from regenerative braking. The main advantage of this protection system is that more than one number of batteries can be connected easily and monitored with the same efficiency.
INTELLIGENT BATTERIES AND PROTECTION:
» Apart from the normal Li-ion batteries the life of rechargeable Nickel Metal Hybrid batteries can also be extended by the use of the intelligent charging system which facilitates the intermediate communication between the battery and the charger.
» The BMS obtains the collective specification about the battery and the input current and voltage information.
» In order to understand in deep about the Battery Management System, we can take the normal mobile phone chargers into account.
» In the world of fast-moving Mobile phones production, the manufacturers and designers are keeping a keen vision on the batteries, the charging time of the batteries is minimized to a greater extend. The adapters of these chargers are rated with certain current and voltage rating by which the The rate of power in watts supplied to the batteries can be calculated.
Laptop Charger :
A typical specification of laptop charger at output is: 20V DC and 2.25 A
P (in watts) = 20* 2.25 = 45 watts (approx.).
