BYD Blade Battery. Source: BYD LFP or LifePo4 batteries are gaining alot of momentum in recent times due to the robustness of its chemistry. This chemistry is capable of sustaining extreme temperatures + other climatic conditions without having much impact on its health. The only thing that can affect LFP battery is the imbalance which exists in the battery pack. What is Imbalance in LifePo4 batteries? Battery pack of any electric car is made up of multiple cells. All these cells are supposed to perform together at equal potential for EV to run smoothly. When one or more cells are not at same SOC (State of Charge) as other cells then it is termed as an imbalanced battery pack. This can cause the cells of the battery pack to degrade non-uniformly, causing the rapid reduction of SOH (state of health) of the whole battery pack. Factors affecting battery to get imbalance 1. Fast charging the battery frequently. 2. Not performing 100% charge regularly on a level 2 charger. Normally car manu...

Source: BYD We all know that all the BYD cars are equipped with LFP batteries nowadays. These battery chemistry has become quite popular in today's time due to its evident advantages over NMC battery cells. We can see lots of other manufacturer's also using lfp battery chemistry nowadays for their Electric vehicles.  LFP batteries are required to have constantly balanced cells at all times. This will help the battery pack to perform at their optimum levels at all times. For this, companies suggests to charge the car all the way up to 100% on regular basis. Doing this will ensure that the battery of your car is at optimum top balanced level at all times. What is happening with MG and BYD Batteries? As we all know, in case of LFP batteries it is very difficult to judge the actual SOC of the battery unless it is charged upto 100% on dropped below 10%, So BMS calculates the SOC based on columb count method. Now when the battery pack has degraded or is imbalanced, it is likely that ...
