Accordingly, for a coherent comprehension of the state-of-the-art of battery charging techniques for the lithium-ion battery systems, this paper provides a comprehensive review of the existing charging methods by proposing a new classification as non-feedback-based, feedback-based, and intelligent charging methods, applied to the lithium-ion.
However, a battery pack with such a design typically encounter charge imbalance among its cells, which restricts the charging and discharging process . Positively, a lithium-ion pack can be outfitted with a battery management system (BMS) that supervises the batteries' smooth work and optimizes their operation .
In their study, following a multi-module charger, a user-involved methodology with the leader-followers structure is developed to control the charging of a series-connected lithium-ion battery pack. In other words, they are exploiting a nominal model of battery cells.
In general, the available lithium-ion battery non-feedback-based charging strategies can be divided into four model-free methodology classes, including traditional, fast, optimized, and electrochemical-parameter-based (EP-based) charging approaches as shown in Figure 3 [36 - 40].
In this costs of the EM-based charging techniques. ing charging. Consequently, compared to non-feedback-based more cycle life, and higher charging capacity. Furthermore, they charging time. These charging techniques, ho wever, hav e high trol structure. ing methods for lithium-ion battery packs. Different charging extending the battery life.
A typical feedback-based battery charging management design includes battery model, state estimator, and model-based controller. A model-based charging method calculates the optimal charging rate of a battery based on its empirical or EM model aiming to optimize the charging process by controlling the polarization voltage [65, 88 - 93].
For a battery pack with multiple connected cells, the intelligent charging method offers a multi-layer control structure with great flexibility that balances complexity and efficiency. This approach allows for multi-objective battery charging to be achieved simultaneously.

The Kazakhstan-China Pipeline (KCP) was main non-Russian route for Kazakh oil exports in 2022. – KCP remains substantially underutilized, as it tends to yield relatively unattractive netbacks given fixed China border price at discount to an international benchmark and provides access to one market (and buyer).
Diesel is the single largest component (product) in Kazakhstan's refinery slate and in its domestic consumption balance; widely consumed within Kazakhstan, diesel is used across many economic sectors, while transportation (trucking) is the single largest consumer. Kazakhstan remained a (small) net importer of diesel each year during 2016-22.
Kazakh authorities remain officially committed to a gradual transition to market-based refined product prices, in keeping with the Eurasian Economic Union (EAEU) goal of launching a common market in oil and refined products in 2025 (e.g. raising the ceiling on gasoline and diesel prices).
