* Reducere ladestrømmen til et tilstrækkeligt lavt niveau så de mest opladede celler ikke tager skade, mens de mindre ladede celler fortsat lades på (det må ikke gøres med Lithium-ion-celler)
* Modulær ladning<ref>http://www.metricmind.com/audi/14-battery.htm</ref>
=== Automatisk udkobling eller indkobling af celler ===
Automatisk udkobling eller indkobling af enkelt(e) celler i en akkumulatorpakke:<ref>[http://www.sciencedaily.com/releases/2015/12/151204094510.htm Fraunhofer-Gesellschaft. (2015, December 4). Electric cars: Batteries with brains. ScienceDaily] Citat: "...If a cell is empty, but the others still have energy stored, the car does not have to stop, like it did before. Rather, the empty battery cell simply decouples from the cluster, acting like a current by-pass. The others continue to deliver energy. "Depending on the cell quality, we can therefore increase the range by at least four percent," explains Pfeiffer." Over time, this effect is amplified: in the case of an old battery, and if the empty cells are replaced, it is conceivable that a range up to ten percent higher can be achieved."...The researchers have already developed a prototype of the battery cell. The challenge is now to miniaturize the electronics and embed them into cells. "We want it to cost less than a euro," Pfeiffer says. Part of the development process is being conducted in the EU project "3Ccar."..."</ref>
* Under opladning kan udkobling af enkelt næsten fuld opladte celler udføres løbende, for hurtigere at oplade de resterende delvis opladede celler.
* Under afladning kan udkobling af enkelt mindre opladede/fuldt afladte celler udføres løbende, for at de resterende delvis opladede celler stadig kan levere energi.
* Under opladning og afladning kan enkelt defekte celler udkobles, så akkumulatorpakke fint fungere på trods af de defekte celler.
