Blog Article

Using temperature as the main state basis for sorting the LiFePO4 battery can solve the problem of insufficient response to the internal working state of Coaster Set the cell.By tracking and monitoring the status of each cell inside the module, which can reflect the consistency of the complex system after large-capacity grouping.Here, the dynamic temperature change of the LiFePO4 battery is detected, the temperature rise and the temperature rise rate are compared.The corresponding temperature rise rate of the old cell were significantly higher than the new cell.

The temperature difference can be used to Drinks judge the consistency of the single cells in the battery module.
