Can lithium iron phosphate battery be charged every day?
Lithium iron phosphate battery and ternary lithium battery belong to lithium battery, but there are some differences in daily maintenance. The charging skills of lithium iron phosphate battery are as follows:
1. In terms of charging frequency, it is possible to charge lithium iron phosphate battery every day, which can realize that the battery is in a shallow cycle state and is conducive to extending the service life of the battery. However, slow charging is recommended.
2. Ensure that the battery is not over discharged. It is better to recharge when the remaining 30% of the battery power is low, which is not conducive to battery maintenance. If the vehicle is not used for a long time, in order to extend the service life of the power battery, it is recommended to charge it every 3 months to avoid the risk of over discharge of the battery.
3. The lithium iron phosphate battery can be charged to 90% or fully charged, and the ternary lithium battery is better charged to 90%. However, lithium iron phosphate needs to be fully charged at least once a week to correct the value of SOC (residual power). The voltage of lithium iron phosphate battery is relatively stable in the range of 15% - 95%. The open circuit voltage method is not accurate enough to measure SOC. If it is not fully charged for a long time, the error of SOC is getting bigger and bigger, and there is a problem of virtual mileage.
