• Cell, modules, and packs – Hybrid and electric vehicles have a high voltage battery pack that consists of individual modules and cells organized in series and parallel. A cell is the smallest, packaged form a battery can take and is generally on the order of one to six ... A secondary battery is one that is rechargeable. Battery Condition
However, the battery pack capacity in a series-connected module is also charged/discharged in the limitation of each single cell''s terminal voltage for the safety issue of a single cell [26]. Thus, each cell capacity has great influence on battery pack capacity. As shown in Fig. 1(a), cell . Equalization strategy
Due to almost no influence on the voltage drift (Fig. 7 f), caused by low intrinsic aging differences and low absolute value of the self-discharge, the battery pack without balancing performs almost as well as the one with dissipative balancing.

The experimental results show that for an initial battery pack temperature of −10 °C, overall charge time is minimized by starting to charge after the battery pack has been heated to 1 °C, and the battery coolant heater energy consumption is reduced by 15 %.
The primary components of a battery pack are the battery modules. The battery modules contain the lithium-ion cells and are usually designed in such a way that their module terminal voltage is below 60 V, and hence they can be handled without additional and expensive safety precautions (see Section 10.2.1).The individual modules …
