The correct way to charge lithium iron phosphate battery pack

The correct way to charge the lithium iron phosphate battery pack is to use the CCCV battery charging method to charge the lithium iron phosphate battery positive ion lithium battery pack battery. The battery charging method is the constant current source after the constant current source. Constant liquidity. Constant working pressure suggestion. That is to carry out the current battery charging in the whole process of the constant current power supply. When the battery voltage reaches V, select the V working voltage constant current source battery to charge, when the current is less than/or do not continue to charge the battery, namely rechargeable battery Filled up now. When using a constant voltage switching power supply battery to charge, it also depends on whether the current is too large. It is recommended not to charge with a too high working voltage. After adjusting the working voltage, make sure that the current does not exceed the capacity of the rechargeable battery. Generally speaking, ammonium sulphate lithium iron battery charging limit working voltage, charging and discharging lower limit working voltage 2~, combing into consideration the charge and discharge volume, charge and discharge median working voltage, battery charging time, constant current power supply volume percentage, safety factor Wait for five levels. For lithium iron phosphate battery positive-ion lithium battery packs, the battery charging limit working voltage is set to ~ more effective, the recommended value is ~V, and the charging and discharging lower limit working voltage is 2.2V~. The battery charger for lithium iron phosphate batteries is different from ordinary lithium batteries. The working voltage of the lithium battery is ampere when the battery is charged, while the lithium iron phosphate rechargeable battery is ampere. When charging the lithium iron phosphate battery lithium battery pack battery, it is the route that the balanced battery charging board is tightly connected. Generally, all batteries are charged in series immediately on both sides. The battery charging working voltage is higher than the lithium battery pack working voltage. When the single-chip microcomputer design verifies that the working voltage of each single-chip microcomputer is designed to design the lithium battery cell, it is equivalent to the parallel-type zener tube. The single-chip microcomputer design battery charging working voltage does not exceed the zener tube value, and other single-chip microcomputer designs are again based on the zener tube Charge the battery through. Since every single power project is now close to being filled up, only balancing each single, so the current is not large, in order to compensate and balance each key. The battery charger only maintains the DC voltage of all lithium battery packs, while the balanced battery charging board ensures that every single quantity is filled after the battery is charged. It is not easy to be filled with a lithium battery cell. Intermittent charging of all lithium battery packs appears. Correct charging method for lithium iron phosphate battery packs. Constant current source battery charging method: During the whole process of battery charging, the output voltage of the battery charging switch power supply is maintained for a long time from beginning to end. According to the change of the concentration and polarization of the positive ion lithium battery pack of lithium iron phosphate battery, actively adjust the current, assuming that all normal working voltages are stable and suitable, you can ensure that the power lithium battery is fully charged, and try to guard against vapor dissolution and moisture damage. The battery charging method only fully considers the change of the single condition of battery voltage, and cannot reasonably reflect the battery charging condition of all rechargeable batteries. The original current is too large, and the power lithium battery is often destroyed. Regarding this defect, there are very few options for charging superheated steam batteries. The second is the constant current power battery charging method: according to the output voltage of the whole process of adjusting the battery charging, the current is maintained for a long time from beginning to end. Sticking to the current will not change, the battery charging speed is relatively low. Constant current battery charging control measures are simple, but because the acceptable current capacity of the lithium battery pack gradually decreases with the battery charging process, in the middle and late stages of battery charging, the power lithium battery's receiving capacity is reduced, and the current usage rate is greatly reduced. The advantages of this product are that the actual operation is simple, convenient, and easy to complete, and the battery charging power consumption is easy to carry over. Constant current source battery charging method: this battery charging method is a simple composition of the two battery charging methods. The first is to use the constant current power battery charging method, and beware of excessive current at the beginning of a constant current source battery charge; use the constant current source battery charging method, and the constant current power battery charging method is used in the second stage to guard against the overcharge condition; The lithium iron phosphate battery lithium battery pack is the same as all other sealed rechargeable lithium batteries. The charging of the battery must be strictly controlled, and charging is not allowed, otherwise the rechargeable battery will be easily destroyed. Lithium iron phosphate batteries generally use the current limiter battery charging method after setting the current. Inverter battery charging method: select the inverter battery charging method to carry out battery charging. In this method, the current amount of the DC power supply remains unchanged, and the switch tube is controlled so that it will be turned off after a period of application for registration, and then the circulation system will be turned off. The benefit of that depends on: When the rechargeable battery is When the battery is charged, the positive ion cycle time inside the rechargeable battery has to be set against a certain time. Assuming that the battery is continuously charged, it is likely to reduce the volume of the rechargeable battery. When the battery is charged for a period of time, adding a break time will allow the positive ions in the rechargeable battery to have a dispersive whole process when the north and south poles erupt, so that the rechargeable battery has a digestible time, and then Further increase the utilization rate of rechargeable batteries and improve the actual effect of battery charging.
