Cell failure and imbalance are critical problems in battery storage systems, especially in series-connected battery strings. The reconfiguration function and the balancing function are both of great importance, but it is very challenging and problematic to own both functions simultaneously. This paper attempts to make contributions on realizing both
IEEE standards recommend that parallel strings be not just of the same capacity but of about the same age, and that circuit resistances for the strings be ''as similar as possible'' to prevent
IEEE standards recommend that parallel strings be not just of the same capacity but of about the same age, and that circuit resistances for the strings be ''as similar as possible'' to prevent imbalances. Yet two recent Intelec papers have clearly debunked these and other myths surrounding parallel strings.

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:
Experienced battery applications engineers speak darkly of ‘circulating currents.’ IEEE standards recommend that parallel strings be not just of the same capacity but of about the same age, and that circuit resistances for the strings be ‘as similar as possible’ to prevent imbalances.
The absence of any theoretical limitation to the number of parallel strings is borne out by the experience of telecom operators, and at least one battery manufacturer allows up to 16 parallel strings, depending on system voltage.3
However, for most of today’s stationary batteries it is better to make parallel connections at the string level. One suggestion is to limit the number of strings in accordance with the system voltage, allowing more parallel strings at lower voltages.
Many telecom operators have a policy of installing adequate capacity to support the system load (i.e. no redundancy), but using a minimum of two parallel strings. This is prudent system design for VRLA batteries, in which cells sometimes fail open or near-open, thus disabling a complete string.
Since the charging is handled and controlled by the charger on each string, each battery pack is only responsible for providing discharge current to the common DC bus. This completely eliminates the possibility of eddy currents and of damage to the charge equipment since each charger is controlled individually by each string's BMS.
