1. Use original or matching brand battery charger
First of all, because the design of the original charger and the corresponding battery specifications are perfectly matched, so the original charger can more accurately charge your battery, reduce the current or voltage mismatch in the circuit to affect the normal chemical reaction of the battery, thus reducing the problem of battery expansion, and the quality of the original charger is strictly controlled to ensure its safety, so choosing the original charger can minimize the risk of battery expansion. The quality of the original charger is strictly controlled to ensure its safety, so choosing the original charger can minimize the risk of battery expansion.
Secondly, if your original charger is lost, you’d better use the charger that matches your battery, take lithium iron phosphate battery as an example, assuming that your lithium iron phosphate battery can accept voltage of 12V, current of 2A, then if you use the battery charger with current of 5A to charge your lithium iron phosphate battery, then it will lead to your lithium iron phosphate battery to generate a lot of heat and accumulate in the battery, and the risk of battery swelling will be minimized. The risk of battery expansion increases.
In addition to considering the battery charger to match your battery, in order to protect the quality of your battery charger, you can choose some branded battery chargers, compared to ordinary battery chargers, branded chargers have international certifications of quality assurance, such as UL certification. Common battery charger brands are Anker, Eneloop, etc. These battery charger brands in the world
2. Reasonable arrangement of charging and discharging the battery
Because overcharging the battery will lead to the accumulation of too much heat inside, resulting in higher internal pressure, which in turn triggers the expansion of the battery, while over-discharging the battery will lead to the over-consumption of chemicals inside the battery, which in turn destroys the structure of the battery, which leads to a higher risk of battery expansion. Therefore, reasonable amperage electromagnetic charging and discharging can effectively reduce the risk triggered by battery expansion.
Regarding charging, it is recommended that you use the float charging method, i.e., when the battery power has reached about 90% of its capacity, you should take a smaller battery to charge the battery and turn off the battery charger in time after it is fully charged, which can minimize the risk of battery expansion.
About discharge, you should not use the battery more than its depth of discharge, assuming a capacity of 100Ah lithium iron phosphate battery depth of discharge of 80%, you should be in the consumption of this lithium iron phosphate battery 80Ah after the battery charge your lithium iron phosphate battery in a timely manner, which can be reduced to a certain extent to reduce the risk of battery expansion caused by the battery.
3. Ensure a good heat dissipation environment for the battery
Because the battery will generate a lot of heat when working, and a large accumulation of heat will cause the risk of battery expansion increases, so to ensure that the battery good heat dissipation environment is an important measure to reduce the risk of battery expansion. First of all, you can place your battery in a ventilated area that is protected from light, which will help the heat to dissipate from the battery quickly, thus reducing the risk of battery expansion.
4. Install a Battery Management System (BMS)
You can install a Battery Management System (BMS) for your battery, which can monitor the status of the battery at any time, including the temperature, current and voltage of the battery, to avoid internal short-circuiting, over-charging and over-discharging, etc., and at the same time, take appropriate measures to address these issues, so that the battery can work safely and stably, which will naturally reduce the risk of battery expansion.
Conclusion
Through the in-depth understanding of the prevention of battery expansion risk related content, you can make corresponding measures to reduce the probability of battery expansion risk, which is very important for your life and property safety, if you want to choose a safer battery, then lithium iron phosphate batteries will be a good choice.
FAQ
A swollen battery is a sign that the performance and safety of the battery have greatly decreased. Generally speaking, for your safety, it is recommended to replace swollen batteries. However, sometimes a slightly swollen battery can be restored by balancing charging and discharging, but you need to know that this kind of restoration method not only requires professional instruments, but also has a very low success rate.
For your battery to try to recover, you can ask a professional to evaluate the condition of your battery, and they will decide whether your battery can try to recover or not based on the evaluation result of your battery. Overall, it is still recommended that you replace your swollen battery in a timely manner.
This is not true, not all batteries will expand, this is closely related to the battery materials, battery technology and external factors, etc. Moreover, the probability of expansion risk is different for different batteries, for example, in lithium batteries, the probability of expansion risk of lithium iron phosphate batteries is lower than that of lithium ternary batteries and lithium manganese-acid batteries. Therefore, you need to pay attention to the specific material of the battery when choosing the battery.
