Why is the state of battery health important?

The battery is the heart of an electric car. Its state of health largely determines the performance and range of the vehicle. A well-maintained battery means a longer service life and consistent performance.

When selling an electric car privately, the condition of the battery is a decisive factor in the value of the vehicle. Prospective buyers want to make sure that the battery still has sufficient capacity and works the right way.

Assessing EV and Hybrid Battery Health: Cardino's SoH Evaluation Tool

Common Battery Issues in EVs and Hybrids Over Time

Battery health can decline due to a variety of factors, leading to reduced performance and possibly increased maintenance needs. Here are some common issues that can occur with batteries after prolonged use:

1. Capacity Fade: Battery capacity fade is one of the most common issues. Over time, the battery loses its ability to hold a full charge. This degradation results in decreased range and more frequent charges needed, impacting the vehicle’s practicality and efficiency.

2. Power Fade: Along with losing capacity, batteries can also experience a reduction in the power they can deliver. This leads to slower acceleration and can affect the overall drivability of the vehicle.

3. Increased Internal Resistance: As a battery ages, its internal resistance increases, which can cause it to heat up more during charging and discharging. This additional heat can accelerate the degradation process and reduce the efficiency of the battery.

4. Cell Imbalance: Battery cells in an EV or hybrid should charge and discharge at similar rates. Over time, cells can become imbalanced, with some cells deteriorating faster than others. This imbalance can affect the performance and longevity of the battery pack as a whole.

5. Premature Voltage Cutoff: Increased resistance and cell imbalance can lead to a situation where the battery's management system perceives the battery as fully discharged at a higher voltage than usual, leading to unexpectedly reduced vehicle range.


As the demand for electric vehicles and hybrids continues to grow, the need for reliable battery health assessments becomes ever more critical. Cardino's SoH evaluation tool offers a detailed and dependable method for determining the state of health of EV and hybrid batteries, ensuring both buyers and sellers can make informed decisions based on accurate data. By incorporating advanced diagnostics and standardized testing procedures, Cardino not only identifies current battery conditions but also helps predict future performance.
