- Battery current measurement
EMUS BMS Mini 3 (MNL034) is a compact, all-in-one BMS device, that autonomously executes all core and utility functions of battery management. It interacts with all other components in the system, monitors cell voltage levels, and controls charging and balancing functions, using various inputs, outputs, and interfaces.
It is designed to use for battery packs consisting of 6 up to 16 cells connected in series and has all key BMS functions integrated into one device. One Mini 3 device can be used for a single battery pack, with the later software release there will be possibility to connect several Mini 3 devices in parallel.
Features:
- Cell voltages and temperatures measurement
- Battery current measurement
- Balancing of the cells
- Protections and warnings adjustable on Control Panel
- Integrated contactor to protect the battery
- Integrated pre-charge circuit to allow soft start of motor controllers
- Connectivity to various types of chargers
- Connectivity to smartphones App
- USB interface that is intended for quick and straightforward connection to a host device (e.g. computer, tablet, smartphone) when configuration, diagnostics, or maintenance is needed
- CAN data interface. Enables to communicate with CAN equipped EMUS devices and third-party devices
- Supports 50, 125, 250, 500, 800 kbit/s and 1 Mbit/s CAN baud rates (default 250kbit/s)
- RS232, a single-ended transmission mode protocol, allows continuously monitor BMS activity using first-party or third-party devices (feature to be active in Q3 2021)
- RS485 is a differential transmission mode protocol, which allows to continuously monitor BMS activity and control chargers (feature to be active in Q3 2021)
- SD card enables to store all sent messages from the EMUS BMS Mini 3 and recover all unexpected situations which occurred in the past (feature to be active in Q3 2021)
- State of Charge (SOC) and State of Health (SOH) allows to monitor cell’s degradation factors. SOC calculations depend on real cell capacity and internal cell parameters
