Product introduction
This series of battery management system mainly used in lithium battery powered electric vehicles, electric boats, and electric equipment. Real time monitoring of the cells voltage, the total voltage of the battery pack, the temperature of the cells, the charge and discharge current. Provide the cells balance management, charge and discharge control, heating and cooling management, and fault information alarm.The system can be connected to the computer through the rs485 interface, and the operating parameters of the system can be monitored and configured by the matching computer software.
The basic control strategy
(1) after power on by the switch, in the case of the battery system is operating normally, both the charge and discharge relays will be closed.
(2) when the battery pack and cell over charge protect voltage occurs, disconnect the charging relay, until reached the release voltage.
(3) when the battery pack and cell over discharge protect voltage occurs, disconnect the discharge relay, until reached the release voltage.
(4) when the charge over and under temperature protect occurs, disconnect the charging relay, until reached the release temperatur
(5) when the discharge over and under temperature protect occurs, disconnect the discharge relay, until reached the release temperature.
(6) when the charging over current protect occurs, disconnect the charging relay, it will not be released until next powered on.
(7) when the discharge over current protect occurs, disconnect the discharge relay, it will not be released until next powered on.
