The most intuitive judgement criterion is the range. If your electric motorbike could travel 80 kilometres on a full charge, and could easily cope with short- and medium-distance trips, then the driving range has dropped significantly after a full charge, and it can only run for 30-40 kilometres or even less, and in the case of no change in charging habits, it means that the capacity of the battery has been seriously degraded. Generally speaking, when the range drops to 60% - 70% of the original, it means that the capacity of the battery has declined significantly, and it is probably time to replace it.
NOTE: It is normal for cold weather to cause a temporary drop in range. However, if the range does not recover when it warms up, it is a battery problem.
Reasons for the decrease in range: It may be that the active substance inside the battery decreases, resulting in a lower ability to store power. For example, the sulfation of the pole plate in lead-acid batteries will hinder the normal charging and discharging of the battery, so that the power can not be fully released; the aging of the core of lithium batteries will also lead to a continuous decline in capacity.
Under normal circumstances, a 60V lithium battery takes about 6 hours to fully charge. If you find that charging only takes 3 hours to show full, and the power consumption is extremely fast when riding, it means that the battery's power storage capacity has seriously decreased, and the battery's internal charging protection, cell capacity, or BMS system may have developed a problem.
On the contrary, if the charging time is significantly longer, or even more than 10 hours is not yet full, the charger does not change the green light for a long time, and the battery heating is serious, this may be the battery internal short circuit, pole plate deformation and other faults. Whether charging too fast or too slow, is the battery issued a ‘distress signal’, need to check in time to determine whether to replace. Abnormal heat when charging: It is obvious that the battery pack temperature is very high (hot), there is a potential safety hazard!
Even if the battery is fully charged, the lack of power when starting is obvious, and it becomes hard to climb the slope and accelerate slowly, which is also an important manifestation of the aging of the battery. 60V battery can provide stable and strong power support for the motor when it is working normally to ensure that the vehicle has plenty of power. However, when the battery performance declines and the output voltage is unstable, the motor will not be able to obtain enough power, resulting in a weakening of power.
When we are in need of a quick start to overtake, the electric motorbike can't boost its speed, which not only affects the driving experience, but also may bring about potential safety hazards. If you find that the power of your electric motorbike is not as strong as it used to be, you should consider whether the battery has reached the limit of its use.
A close look at the appearance of the electric motorbike battery can also reveal signs that it needs to be replaced. If the battery shell appears obvious bulging, deformation, this may be due to the battery internal short circuit, overheating, resulting in gas accumulation can not be discharged caused by. The bulging battery not only performance is impaired, there is also a great security risks, at any time may trigger spontaneous combustion, explosion and other serious consequences, once found must be replaced immediately.
In addition, check whether there is corrosion and rust on the battery connection parts. If the battery poles and connecting wires are seriously oxidised, it will lead to poor contact, increase resistance and affect the charging and discharging efficiency of the battery. Although this situation can be temporarily improved by cleaning and maintenance, if the corrosion problem recurs, it also indicates that the overall performance of the battery is declining, and replacing the battery may be a more thorough solution.
The service life of 60V electric motorbike battery is closely related to the type. Lead-acid batteries generally have a service life of 2-3 years, with a cycle charge/discharge number of about 300-500 times; lithium batteries have a relatively long service life of 5-8 years, with a cycle charge/discharge number of about 800-1800 times. However, in actual use, the life of the battery is also affected by the use of the environment, charging habits and other factors.
For example, frequent use in high or low temperatures, frequent deep discharging, and unregulated charging methods (e.g., overcharging, using mismatched chargers) will accelerate battery aging. If your battery's usage time is close to or exceeds its theoretical lifespan, even if its current performance is still good, it is recommended to prepare for replacement in advance to avoid unexpected situations such as sudden power cuts while driving.
If you are still unable to determine whether the battery should be replaced by the above methods, you may wish to test it with the help of professional equipment. You can send the battery to an electric motorbike repair shop or after-sales service, and use tools such as battery capacity tester and internal resistance tester to accurately measure the battery's actual capacity, internal resistance and other parameters. Professionals will give scientific recommendations for replacement based on the test data, combined with the use of the battery.
In addition, some high-end electric motorbikes are equipped with a battery health monitoring system, which allows you to view the status information of the battery in real time on the dashboard of the vehicle or on the mobile phone APP, such as the remaining capacity and the health score, etc., and provides more intuitive data support for users to judge whether the battery needs to be replaced.
To judge whether a 60V electric motorbike battery should be replaced, it is necessary to integrate various factors such as range, charging time, power performance, appearance and service life. Timely replacement of aging batteries not only improves the riding experience, but also ensures travelling safety.
