A crucial component of a Battery Management System (BMS) that guarantees timely and effective communication with other systems or components in a specific application is the communication protocol. A communication protocol, in its simplest form, is a collection of guidelines that specify how two or more entities (in this example, electronic devices), interact with one another.

Conventional telecommunication rooms use lead-acid batteries for power backup. The normal operating temperature of lead-acid batteries ranges from 20°C to 25°C, while the operating temperature range of telecom equipment, power supply, diesel generator and air conditioner is wide. Lead-acid batteries become the key heat sensitive source.
Possible applications of models are the optimization of battery management, i.a. cell scheduling al-gorithms and the shaping of the discharge profile of the bat-tery under performance constraints. This enables the maxi-mization of the battery life time by trading off performance using information about the State of Charge (SoC).
In the context of electrical engineering and for the spe-cial purpose of battery management and monitoring, abstract models taking the form of equivalent circuits are a popular and valid choice. Also, a trade-off between the complexity of the equivalent circuit (mainly the number of RC elements) and its accuracy should be accepted.
