An IPT-Based Voltage Equalizer with Voltage-Doublers for Battery-String
Existing multiple-receiver-IPT-based equalizers targeting individual batteries are not suitable for balancing multiple battery cells, because one receiving coil can be only used to charge one battery cell, resulting in lots of component consumption and complicated systems. Thus, a IPT-Based voltage equalizer with voltage-doublers is proposed in this paper to address this

Even if a cell in one string is shorted, its effect on the overall string will be compensated for by a higher charge current through that string. The only time that some strings may discharge into others is when left standing on open circuit. If one string contains a cell that is short-circuited, that cell will depress the inherent string voltage.

6 FAQs about [Battery string charging source]
Can a battery energy storage system provide a fast charging station?
This paper introduces a novel design of an electric vehicle (EV) fast charging station, consisting of a battery energy storage system (BESS) with reconfigurable cell topology. The BESS comprises two battery strings that decouple the power flow between EV and grid, to enable charging powers above the grid capacity.
What is string cell battery technology?
String cell battery technology allows the depleted cells to be swapped for fully charged cells in a process called cell swapping. Cell swapping differs from traditional battery pack swapping technologies in that only the cells are swapped. Swapping cells in a string battery typically takes less time than traditional petrol cars take to fill up.
What is a string battery?
Tanktwo also provides design and simulation tools to aid in the development process. The string battery solution is based on a distributed and modular design that consists of automatically self-organizing cells, which are called string cells. The string cell is a modular and independent unit inside the string battery.
How does a battery charger work?
This approach uses one battery charger per string. The BMS in each string directly controls the charger for that string, meaning that the charge can be controlled very precisely. 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.
What are the advantages of a string cell battery?
An additional advantage of the string cell battery is the flexibility allowed in shaping the battery enclosure. Compared to batteries with a fixed architecture, the string cell battery allows EV designers to easily configure the string battery’s enclosure so that it conforms to the size and shape of different vehicle platforms.
