Hence, the introduction of lithium batteries was seen and perceived as a major breakthrough in this industry. The reality of using them was a far cry from what many had expected. Before their advent, rechargeable batteries have struggled to meet the expectations of those who use them. Lithium ion batteries have brought about some remarkable changes in the world of rechargeable batteries today. That partial charging and discharging is what is assumed to create the perceived memory effect in the battery. Consequently, the batteries will be charged at that instance. The effect has been attributed to the several cycles of discharging and charging during the lifetime of the battery.Īccording to the report, during every braking session of a hybrid car, the engine switches to generator mode at that time. It is even said the memory effect thing is more pronounced in hybrid cars than it is in any other industry. There is also the belief in the electric vehicle industry that lithium ion batteries have performed below expectations due to their memory defects. The voltage changes they talk about is actually negligible. That is what is wrongly interpreted by many as depletion in voltage levels, ultimately leading them to believe that memory effect is normal in lithium batteries. But while many people think of this as a memory defect, the voltage at the cathode of those lithium ion batteries is believed to remain steady after going through so many charging cycles over an extended period. According to them, a certain level of memory effect has been discovered in the cathode of some lithium ion batteries. Researchers and scientists in some quarters still believe that lithium ion batteries do exhibit memory effect issues like their counterparts. Though there is still a whole lot of debate going on in that arena. The introduction of lithium ion battery was one thing that changed the trend in memory effect. Since, the trend has been like this for decades, some people think that this feature is also found in lithium ion batteries. It has equally been a negative trend in some other rechargeable batteries in this category. Memory effect has been an age-long effect on Nickel Cadmium as well as Nickel Metal Hydride batteries. That way, it will become difficult to ascertain the true charging status of the battery. Second, the relationship between the charge status and voltage will be altered. First, as you would naturally guess, the capacity of the battery is drastically reduced by this effect. Let us take a look at some of the consequences of memory effect in rechargeable batteries.īattery experts have been able of identify two negative consequences that come with memory effect in batteries. As such, scientists and researchers have been doing what they can to upend this ugly trend. This may look like a simple effect, but it has some serious adverse negative effects on the battery. The voltage will be inadequate to power the device efficiently. In other words, even when the battery has been discharged, it still ends up supplying a voltage that is lower than what you would have expected. Memory effect is known to occur when the usual voltage of the battery continues to drop with time due to incomplete discharging and charging.
