The charging and discharging currents and C-rates are usually defined by the manufacturer in the data sheet of the cell. Voltages in lithium-ion cells correspond to the state of the charge of the cell. Voltages of <2.5 V in a lithium-ion cell increase the probability of the cell being dead.
This paper presents a transformative methodology that harnesses the power of digital twin (DT) technology for the advanced condition monitoring of lithium-ion batteries (LIBs) in electric vehicles (EVs). In contrast to conventional solutions, our approach eliminates the need to calibrate sensors or add additional hardware circuits.
The temperature on the surface of batteries can typically be monitored by various temperature sensors and infrared thermal imaging equipment. The internal temperature of LIBs increases during its operating cycle in direct proportion to the generated heat amount .
This paper proposes to create a lithium-ion battery pack (12 V, 60Ah) monitoring system using IoT-based. The parameter of a lithium-ion battery can be monitored, such as battery capacity, voltage, current, and power. Real-time data is updated automatically per minute and is visible on the LCD in the battery case and smartphone.
Monitoring data helps to optimize battery operation and charging strategies, extend battery life, enable early diagnosis of faults and improve battery efficiency. Effective monitoring systems offer data support for the evaluation of LIBs health and the management of smart LIBs.
As discussed earlier, temperature, current and voltage are parameters that determine whether the cell can perform efficiently or not. Lithium-ion cells have high energy density, which means that they are volatile and can be dangerous to their surroundings in the case of thermal breakdown. Therefore, constant monitoring is required [ 23–25 ].
Current Sensing Considerations in Li-ion Battery Management
Battery management requires bi-directional current sensing to monitor both charge and discharge current. It is important to check this specification on current sense amplifiers since some of them are intended for unidirectional use only. It is also useful to note that a bi-directional current sense amplifier can always be used for ...

Debunking Lithium-Ion Battery Charging Myths: Best Practices …
The charging process reduces the current as the battery reaches its full capacity to prevent overcharging. For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the charger switches to a regular voltage mode, tapering the current down until the charge is complete. This method ensures the battery is not …
