Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
Since lithium cells must be managed on a cell level, parallel lithium strings dramatically increase the complexity and cost of the battery management and introduce many additional points of failure and failure modes not found with a single string.
Lithium batteries are widely applied in new energy vehicles and related energy storage industries due to their superior performance. The application of an equalization circuit can effectively reduce the inconsistency of the energy of the battery pack, thereby extending the service life of the battery pack.
Based on the previous study, in this research a new cell-to-cell balancing circuit for lithium-ion battery strings is proposed to overcome the drawbacks of the conventional cell balancing methods. In the proposed topology, the charge is transferred from a high-voltage cell to a low-voltage cell directly by using a push-pull converter.
A battery string with a large number of cells connected in series and in parallel is necessary for many applications that require high power and high voltage, such as electric vehicles (EVs), hybrid electric vehicles (HEVs), and energy storage systems (ESSs) [ 1 ].
Lithium-ion battery cells are used for energy storage in many industrial sectors, such as consumer electronics or electromobility.
