Design of the Voltage Detecting System for Electric Cars Lithium-ion Batteries
The lithium-ion battery is required accurate voltage measurements to determine the state-of-charge and equalization management by open-circuit voltage method in the battery management system.Existing voltage measurements have some deficiencies.In this paper,a measurement the voltage of electric vehicle lithium-ion battery system is presented which using light coupling control switch array.The principle of circuit is analyzed in detail and gives the experimental data.The experiments show that the circuit can be reliably and accurately on the series battery voltage measurement,which has advantages of good consistency anti-electromagnetic interference,actual value etc.
