Battery Cell balancing is the process of managing the states of charge for each battery cell in a battery pack. It’s typically done by monitoring individual cells and transferring charge between cells to ensure that they’re all at the same level. This helps to prevent any one cell from reaching 100% charged, which can cause it to heat up, short circuit or even explode. The better your battery cell balancing strategy is, the less likely these things will happen.
why Cell balancing matters to our battery life?
Because lithium-ion batteries charge and discharge unevenly, cells can get out of balance. The simple act of charging and discharging a battery cell changes the resistance in the cell. When one cell becomes out of balance with the others, it means that it’s either loosing or gaining more energy than the rest of them. This causes the voltage to fluctuate at different parts of its charge cycle, which can be dangerous if not corrected quickly.
To keep this from happening, you need to use battery balancing techniques. These are small circuits that monitor voltages between cells during use. They then communicate back to your charger when they detect an imbalance in order for it to stop charging or discharge cells until they’re balanced again.
What happens in case of cells imbalance
There are a couple of risks associated with misbalancing your cells. The first risk is that the battery’s performance will be weakened. This is because a poorly balanced pack will not be able to store a high enough charge to power your car. The second risk is that it will cause permanent damage to the battery. Misbalancing the cells can lead to an overcapacity of electrons on one side, which can then continue to distribute themselves unevenly and reduce the life span of the battery.
How does battery cell balancing improve battery life?
Battery cell balancing is a process of regulating the battery voltage to equalize all cells. This ensures that each battery cell, no matter how deeply it’s discharged, will receive the same charge. Cell balancing also prevents any one cell from receiving more charge than another, which can drastically reduce the lifespan of your batteries.
Battery cell balancing has been shown to increase the lifespan of a battery by up to 20% in testing. The process is able to monitor the voltage level of each individual cell and can balance them accordingly. This ensures that all cells are at the same voltage level, allowing for even discharging. Battery cell balancing can be used with any type of battery – lead acid, nickel-cadmium, nickel metal-hydride, or lithium ion.
What are the design considerations for a cell balancing system?
Cell balancing is a type of battery management system that enables an electric vehicle to run on a single charge for a considerably longer period of time. It is a control system that balances the voltage across all cells in a series so as to keep the voltage from decreasing due to one cell being empty. This optimizes runtime and extends the life of the battery pack. With leading analytics solutions provider such as iRasus & others, you can remotely analyze and balance the cells in your battery pack, that have gone out of balance.
In short, battery cell balancing is necessary because as lithium-ion batteries are charged and discharged they can become unbalanced. If they are allowed to continue like this they will result in uneven wear and degradation of the battery. A slight imbalance happens over time anyway, but if the cells are properly balanced the problem can be corrected without harm by using the appropriate technologies. Essentially, battery cell balancing is the way to prolong a battery’s life so you don’t have to replace it prematurely.
