The global adoption of new energy vehicles (NEVs) is accelerating, making the maintenance of their core component—the battery—particularly critical. As the “heart” of an NEV, the battery directly impacts the vehicle’s performance and lifespan. Therefore, understanding how to effectively maintain the battery and the equipment required for maintenance is essential for every NEV owner.
Importance of NEV Battery Maintenance and Common Issues
The performance of an NEV battery directly affects the vehicle’s range and overall driving experience. However, as usage time increases, battery performance often declines, which not only reduces the driving range but may also lead to higher repair costs.
Common Causes of Battery Performance Degradation
The degradation of NEV battery performance is typically caused by multiple factors, including improper charging/discharging, temperature fluctuations, overuse, and more. Additionally, electrolyte depletion and internal short circuits are significant contributors to reduced battery capacity. If left unaddressed, these issues can accelerate battery aging.
Differences in Maintenance Needs Across Battery Types
Different types of NEV batteries, such as lithium-ion and nickel-metal hydride batteries, have distinct maintenance requirements. Lithium-ion batteries are sensitive to temperature changes and must operate within specific temperature ranges, while nickel-metal hydride batteries require periodic deep discharges to maintain capacity. Therefore, understanding the characteristics of different battery types and performing targeted maintenance is crucial.
The Role of Regular Maintenance in Extending Battery Lifespan
Regular professional maintenance for NEVs can effectively extend battery life and enhance overall vehicle performance. Routine inspections help identify potential issues early, preventing more significant losses. Additionally, using charging/discharging equipment properly can minimize adverse effects on the battery.
Analysis of Mainstream NEV Battery Maintenance Equipment and Guheng Product Recommendations
To ensure the smooth operation of NEVs, the market offers various high-efficiency battery maintenance devices. These tools not only help detect and repair common faults but also provide data support for informed decision-making. Below are Guheng’s recommended products for different maintenance needs:
Functions and Applications of Battery Balancers
A battery balancer is a critical device for equalizing the charging/discharging states of individual cells. It effectively addresses issues caused by overcharging or undercharging specific cells, improving overall battery consistency and stability. In daily use, it is primarily suited for professional repair shops rather than outdoor emergencies due to its non-portable nature.
Applications of Battery Testers in Fault Recovery
When an NEV exhibits a significant drop in range, a repair device can play a vital role. Using specialized pulse technology, it deeply activates and restores damaged cells, bringing them back to optimal working conditions. Such devices are mainly used by professional repair services due to their complex operation and need for technical expertise.

Comparative Analysis of Efficient Battery Maintenance Equipment Parameters and Guheng Solutions
When selecting maintenance equipment, it is important to consider not only functionality but also technical parameters to ensure compatibility with the vehicle and optimal performance.
Voltage Support Range and Vehicle Compatibility
Different vehicle models use varying power systems, so it is essential to ensure that balancers or testers support the corresponding voltage ranges. This affects both the device’s functionality and the final maintenance results.
Discharge Current and Charging/Discharging Efficiency Comparison
Discharge current impacts system efficiency during operation. Therefore, selecting devices with high discharge current capacity and efficiency is crucial. Some advanced products feature intelligent discharge current adjustment to adapt to different working conditions, maximizing cell protection.
Operating Systems and Data Management Capabilities
Modern testing and repair devices often come with intelligent operating systems that automatically record and analyze data. This is highly beneficial for long-term tracking of vehicle health. Additionally, such data serves as a valuable reference for future maintenance, making products with robust data management capabilities a wise choice.
Equipment Selection Recommendations for Different Scenarios and Guheng Product Matching
In NEV maintenance, different scenarios require different equipment to ensure efficient and precise battery maintenance.
Recommended Models for 4S Shops and Repair Centers
4S shops and professional repair centers typically handle battery issues for multiple vehicle models, making multi-functional, integrated devices an ideal choice. These devices combine balancing, testing, and repair functions, quickly adapting to various battery maintenance needs. They often feature powerful data analysis capabilities and user-friendly interfaces, enabling technicians to diagnose and resolve issues swiftly. Additionally, their design prioritizes durability for high-frequency use, ensuring consistent performance over time.
Solutions for Individual Users or Small Repair Shops
Individual users and small repair shops often have limited budgets, so balancing performance and price is key. Simple, easy-to-use small testers or portable balancers are excellent options. These devices typically feature intuitive interfaces and automated workflows, making them accessible even to non-professionals. They also include basic data recording functions to help users track battery status and perform simple analyses.
How to Use and Maintain Battery Maintenance Equipment Scientifically
Proper use and maintenance of battery maintenance equipment can extend its lifespan and ensure optimal performance, providing reliable support for NEVs.
Correct Operating Procedures and Precautions
Correct operation is essential for device functionality. Before use, carefully read the product manual and follow the instructions strictly. When connecting the battery, ensure correct polarity to avoid short circuits or damage. Additionally, confirm that the vehicle’s power is disconnected before any testing or repair work to ensure safety. If abnormalities occur during operation, stop immediately and investigate the cause to prevent further damage.
Daily Maintenance Methods to Enhance Device Stability
Daily maintenance is crucial for device stability. Regularly clean the casing and vents to prevent dust buildup that could affect heat dissipation. For devices with moving parts, such as cables and plugs, inspect them periodically for wear and replace damaged components promptly. When not in use, store the device in a dry, ventilated area away from direct sunlight to prevent aging.
Troubleshooting Common Issues and Solutions
Even high-quality maintenance equipment may encounter issues. Therefore, knowing how to troubleshoot common problems is essential. For example, if test results are abnormal, first check for loose or poor connections. If the device fails to power on, verify the power cord and socket. If self-troubleshooting fails, contact professionals for repairs to avoid further damage from improper handling.
