METHOD TO ESTIMATE THE CHARGING TIME OF LITHIUM-ION BATTERIES AND CHARGING MONITOR |
摘要 |
The present disclosure provides a method to estimate the charging time of a lithium-ion battery comprising: obtaining a temperature (T), a charging current (Ic) and a charging voltage (V) of the lithium-ion battery during a charging procedure, wherein during the charging procedure the lithium-ion battery is firstly charged in a constant-current charging mode (CC Mode) with a constant-current (I) and then charged in a constant-voltage charging mode (CV Mode); when the lithium-ion battery is charged in the constant-current charging mode, obtaining a constant-current charging time (tcc) and obtaining a constant-voltage full charging time (tcv) in the constant-voltage charging mode according to the temperature, so as to obtain a charging remain time of the lithium-ion battery; and when the lithium-ion battery enters the constant-voltage charge mode, obtaining a constant-voltage charging remain time (tcv′) according to the temperature and the charging current. |

1. A method to estimate the charging time of a lithium-ion battery comprising:
obtaining a temperature (T), a charging current (Ic) and a charging voltage (V) of the lithium-ion battery during a charging procedure, wherein during the charging procedure the lithium-ion battery is firstly charged in a constant-current charging mode (CC Mode) with a constant-current (I) and then charged in a constant-voltage charging mode (CV Mode); when the lithium-ion battery is charged in the constant-current charging mode, obtaining a constant-current charging time (tcc) and obtaining a constant-voltage full charging time (tcv) in the constant-voltage charging mode according to the temperature, wherein a charging remain time of the lithium-ion battery is the constant-current charging time added to the constant-voltage full charging time; and when the lithium-ion battery enters the constant-voltage charge mode, obtaining a constant-voltage charging remain time (tcv′) in the constant-voltage mode according to the temperature and the charging current, wherein the charging remain time of the lithium-ion battery is the constant-voltage charging remain time. |
