In recent years, with the rapid popularization of new energy vehicles, battery degradation has gradually become a major pain point for car owners and after-sales service centers. Even for the same model, the battery range performance of different vehicles varies significantly, and one of the key factors is “individual battery balance.” Imbalance in individual batteries not only accelerates battery degradation but may also pose safety hazards. As a provider of new energy service technology solutions, Guheng Energy has developed a portable individual battery maintenance device (hereinafter referred to as “maintenance device”) that enables rapid and accurate charge and discharge maintenance, providing reliable support for adjusting the voltage difference between individual battery strings, thus safeguarding battery life and safety.
The Dangers of Imbalance in Individual Batteries
Accelerated Battery Degradation
New energy vehicle battery packs consist of multiple individual batteries. When the capacity of some batteries decreases rapidly, it leads to a significant acceleration in the overall battery pack capacity degradation rate. Taking an electric vehicle battery pack as an example, if the voltage deviation between cells (or individual cells) exceeds 0.05V, even if other batteries remain in good condition, the overall battery pack’s range will be significantly affected. For after-sales service centers, this means an increased need for frequent battery testing and replacement.
Increased Safety Hazards
Imbalanced individual battery cells not only affect performance but can also lead to safety issues. Overcharged or over-discharged batteries are prone to abnormal temperatures, even thermal runaway, posing a risk of combustion or explosion. Guheng Energy’s portable individual battery maintenance device can monitor individual cell voltage and temperature in real time, identifying abnormal cells early and reducing safety risks.
Increased Maintenance Costs
Neglecting individual cell balancing over a long period accelerates the overall aging of the battery pack, increasing maintenance costs. For fleets or large after-sales service centers, replacing an entire battery pack will place a significant financial burden. Regularly using an individual battery maintenance device for balancing maintenance can effectively extend battery life and reduce replacement frequency.

Single-Unit Battery Testing and Balancing Operation Guide
Preparation
- Confirm battery pack status and charging status.
- Check power supply and connection cables are intact.
- Wear necessary safety protective equipment, such as high-voltage insulating gloves and goggles.
Testing Steps
- Connect the wiring harness of the portable single-cell battery maintainer to the positive and negative terminals of the individual cells in the correct order.
- Start the testing program and read the individual cell voltage.
Balancing Operation
- Charge and discharge the individual cells.
- Start the device until the voltage difference is within a safe range.
- After completion, confirm that the individual cell voltage has reached the set value.
Data Interpretation and Judgment
- A voltage deviation between cells of less than 0.02V and an internal resistance difference of less than 5mΩ indicates good balancing.
- A voltage deviation between cells of greater than 0.05V requires close monitoring or battery replacement.
Operating Advantages of the Portable Maintainer
Fast Testing, Saving Time
Guheng Energy’s portable single-cell battery maintainer uses a single-channel output design, allowing one technician to quickly complete individual cell testing, with efficiency far exceeding traditional manual testing methods.
Preventative Maintenance, Extended Lifespan
Regular single-cell balancing slows down the overall battery degradation rate, resulting in more stable battery life. Compared to traditional methods that only focus on the total battery voltage, single-cell balancing is more scientific and effective, reducing sudden failures.
Safety and Reliability The device features multiple protection
mechanisms and supports air cooling to ensure stability. Combined with accessories included with the portable single-cell battery maintenance instrument, operational safety and reliability are further enhanced, making it suitable for various new energy battery maintenance scenarios.
Conclusion
The rapid degradation of new energy vehicle batteries is often not accidental, but rather the result of the long-term neglect of “uneven distribution of individual cells.” Scientific testing and equalization maintenance can effectively slow down battery degradation, reduce safety risks, and save maintenance costs. As a professional provider of new energy service technology solutions, Guheng Energy’s series of equalization maintenance instruments, with their advantages of convenient operation, accurate data, and safety and reliability, help after-sales service points, fleets, and individual car owners achieve efficient daily maintenance. Regularly using a portable maintenance instrument for single-cell equalization not only keeps the battery in optimal condition but also provides strong support for the range stability and lifespan of new energy vehicles. Choosing Guheng Energy products means choosing a scientific, professional, and reliable battery maintenance solution.
FAQ
