BMS Easy - Module for thermal protection of LiFePO4 cells

BMS Easy Module for thermal protection of LiFePO4 cells Module for protecting a battery cell or cell block from overheating. EasyT modules can be functionally connected together with EasyV modules to create basic protection for 12V, 24V, 48V etc. batteries. Up to two thermal sensors can be connected to one EasyT module. Function: If the temperature of the monitored cell or cell block is lower than the specified operating maximum, the module output relay is connected to the COM - NO position and the signaling LED flashes at an interval of approximately 3 s. If the temperature rises above the permissible limit, the relay switches to the COM - NC position and the LED does not flash. Simple, durable and reliable electrical design (without SW) Easy module connection and installation Output galvanic isolation (bistable relay) Galvanically isolated inputs for common module reset (optocoupler) Application: Basic protection for simple systems (backup power supply, caravans, chalets, etc.) Double (backup) protection for advanced BMS systems Double warning system for control systems Meets the condition of automatic shutdown in the event of a fault In combination with the BMS Easy module, it meets the basic requirements of the IEC 62619 standard for the protection of battery systems. Basic connection of Easy and Easy T modules for voltage and temperature protection If a cell goes out of the permitted voltage range or the temperature of the cell block exceeds the permitted temperature, the relay on the relevant Easy module switches to the NC position, the KM1 contactor loses voltage on the coil and disconnects the power supply. Basic battery protection according to IEC 62619 with external control circuit power supply For more advanced systems, an independent 24 V DC backup power supply is available for the control circuits. This can be used to power the EasyT module, the power contactor and its auxiliary relay.
