Milbay Australia offer a range of scalable battery management systems compatible with our range of Lithium Phosphate (LiFePO4) cells in system voltages from 12V DC to 900V DC.
Whether you’re looking for an intelligent battery management system or complete battery system for large scale fixed energy storage, public transport or a personal electric vehicle conversion Milbay can supply a solution to meet your project requirements.
The E-Pow™ BMS platform is suitable for a wide range of electric vehicle battery systems for commercial vehicles, passenger cars, bus and special vehicles, and is compatible with lithium manganate, ternary, LiFePO4 (Lithium iron phosphate) and Lithium titanate battery cells. The E-Pow EV05 flexible modular platform allows battery designers to locate the battery cells in seperate environmentally controlled battery enclosures connected in series with centralised battery system management.
Topology: BCU (Battery Control Unit / main controller) plus one or more BMU (Basic Management Unit / slave controller)
Cell Balancing: Passive (dissipated) equilibrium:100mA
CAN communication Vehicle CAN (500K), charging CAN (250K), internal CAN (500K)
Country of manufacture China (mainland)
A working system design requires a minimum of 1 x BCU main controller unit plus a minimum of 1 x BMU slave controller as each unit performs different tasks within the battery management system.
The master BCU communicates with the slave BMUs over a dedicated internal CAN communication channel to create a total Battery Management System (BMS).
Configurations up to 300 cells in series (900VDC)
Multiple Temperature sensor
Fan and heater control
CAN communication integration
Configuration software (PC based)
Suitable for modular battery systems
Suitable for slow or FAST charging
BCU, BMU and cell connection cables customised on request
Master BCU modules communicate accross CAN network channels with slave BMC modules and other CAN nodes such as the vehicle controller and battery charging system to undertake intelligent actions and adjustments to the battery system in real time.
BCU (Battery Control Unit) module manages
Overal battery system discharge and charge
Battery system performance.
Calculating SOH and SOC values
Performing battery system OBD malfunction analysis
CAN battery system messages and alarm alerts.
BMU (Basic Management Unit) slave modules manage
Individual battery cell voltage detection
Single cell temperature detection
Cell balance management
Balanced failure self-diagnosis functions
Battery enclosure thermal management (heating + cooling).
