Every EV owner wonders, "How much battery do I have left?" Here is how Dr.EV answers.

Below are two Tesla charging examples. Both show cell voltage behavior during charging. The difference becomes clear near the upper SOC range. One case shows balancing recovery.The other shows a condition where balancing can no longer recover the imbalance. Case 1: Balancing Recovers In the first graph, look at the circled area near high SOC. As charging progresses, the thickness of the cell voltage band becomes thinner. The spread between the highest and lowest cells gradual

Model 3 and Model Y remain the efficiency leaders, while Model X and Cybertruck show higher Wh/mile as expected.

One of our Dr.EV users recently asked us a common question: “Why is CB-R bad? And what can I actually do about it?” CB-R is a Dr.EV indicator designed to detect cell imbalance. Why cell imbalance is not good for your Tesla. When cells are imbalanced, the usable energy of the entire battery pack is limited by the weakest cell. In this case, we guide slow charging help passive cell balancing working well. Here is real graph. As SOC goes up, cell voltage differences usually get
