A kind of battery management method and system suitable for echelon battery

The invention discloses a kind of battery management method and system suitable for echelon battery, method includes：It is monitored processing by one group of slave pair single battery group in parallel, the monitoring processing includes the voltage for monitoring battery, monitors the temperature of battery, monitors the current distribution of every parallel branch and to one group of single battery group progress dissipation type equilibrium in parallel；According to the monitoring handling result of single battery group, the state of entire battery pack is determined by host；System includes memory and processor.The present invention realizes the management to each single battery in battery pack, and each slave only manages one group of single battery group in parallel, when being needed replacing there are one cell damage, it is only necessary to and corresponding slave is handled, greatly reduces and safeguards complexity, it is efficient；In addition, the battery types in the battery pack of the present invention are various, it is applicable to echelon battery, practicability is high, can be widely applied to monitoring and the control field of battery.
