Abstract:
The present invention discloses a method and device for monitoring state of charge and state of health of a battery, and relates to the technical field of battery. The method comprises: firstly, passing ultrasonic waves through a lithium-ion battery in different SOCs at different charging and discharging currents to obtain acoustic parameters, and then establishing respective corresponding relationships between the acoustic parameters and the lithium-ion battery SOC and SOH; and secondly, monitoring the acoustic parameters of a lithium-ion battery, and then estimating SOC and SOH of the lithium-ion battery by combining the monitored acoustic parameters with the respective corresponding relationships between the acoustic parameters and the lithium-ion battery SOC and SOH. The invention further provides a device implementing the above method. The method and device can monitor the battery SOC and SOH in a brand new way different from the electricity parameter measurement. The method can effectively monitor SOC and SOH of lithium-ion batteries of various types and shapes and thus has a good application prospect.

Claim (Index 5):
The method for monitoring SOC and SOH of a lithium-ion battery of  claim 1 , comprising:\n firstly, passing ultrasonic waves through a healthy lithium-ion battery in different SOCs at different charging and discharging currents to obtain respective flight times of a specific wave peak in the ultrasonic waves, and then to obtain respective flight times of the specific wave peak passing through the healthy lithium-ion battery at different charging and discharging currents; and secondly, passing ultrasonic waves through a lithium-ion battery in different SOCs at different charging and discharging currents to monitor respective flight times of the specific wave peak passing through the lithium-ion battery, so that if the monitored flight times increase abnormally compared to that of the healthy lithium-ion battery, it is determined that the lithium-ion battery SOH is poor.
