Features: TBMS.master
TBMS.master is the base system to protect and manage a 12 volt battery (four lithium cells)
It comes fully assembled and configured for a standard installation. It just needs to be connected to the cells.
TBMS.master includes:
- main unit in a 160 x 114 x 46 cm enclosure with:
- battery wire harness (four cell connectors, a fuse for each cell connection, and a ground)
- six relay outputs
- one connector for the remote indicator panel
- one connector for a current measuring shunt
- one connector for the computer or the TBMS.monitor option
- remote indicator panel (10 meter cable)
- USB cord to connect a PC
- PC application TBMS.config to configure the BMS, monitor cell status and run diagnostics (Windows)
Features
- protects & manages four lithium cells connected in series (12 volt battery)
- for all lithium chemistry from 2 to 5 volt per cell
- only 5 wires to connect to the battery cells and the BMS is operational
- all connections to the battery are protected with a fuse
- deported indicator panel with 5 led, a buzzer and buttons to silence the buzzer, reset the relay outputs and activate emergency protection
- 6 isolated and protected relay outputs (2A)
- three TBMS.slave can be connected in a daisy chain to manage and protect a battery up to 48 volt
- RS485 / ModBus connection to configure the BMS, monitor the battery and run diagnostics from a computer (standard USB connection)
- keeps cells voltage within a few millivolt at all time – activated by a user defined voltage difference between cells (with or without compensation for each cell’s internal resistance*)
- simultaneously discharges the cell with the highest voltage and charges the cell with the lowest voltage (high efficiency energy transfer without any heat dissipation)
- 2 Amps bidirectional current
- voltage of each cell (+/- 0.5 mV)
- temperature of each cell (+/- 0.5 °C)
- current* in or out of the battery (+/- 5 mA)
- battery state of charge*
- battery state of health*
- number of charge cycles* for the battery
- Each trigger’s activation and deactivation is fully programmable:
- based on cell voltage, cell temperature, battery SOC* or current*
- whether a measure is high, low or there is a differential between cells
- independent trigger ON and OFF values (hysteresis)
- Each trigger can activate:
- any of the 4 led on the indicator panel (on, off, blink)
- any of the 6 programmable relays (with a configurable time delay)
- an event that is recorded in TBMS.monitor (option)
- 10 preset triggers:
- warning level for voltage and temperature (high, low, cell differential)
- alarm level for voltage and temperature (high, low)
- 3 preset relay outputs:
- disconnect charge
- disconnect load
- isolate battery
- activation of indicator panel led:
- voltage trigger: led ON / temperature trigger: led BLINK
- warning trigger: yellow led / alarm trigger: red led
- different led for high, low and differential trigger types
- Emergency push button activates the battery disconnection relay
- green heart beat led for operation and balancing status
- combination of 4 led for warning and alarm events (red / yellow)
- 80dB buzzer with “silence” push button
- push button to reset the relays
- emergency push button to activate selected relays (configurable)
- relay outputs are “dry” contacts (no voltage / no polarity)
- each trigger and the “emergency” button can activate zero, one or more relay outputs
- configurable time delay between relays if more than one relay is activated by a trigger / “emergency”
- each relay can handle 2 Amps continuous (7 Amps for 0.5 second) – protected by re-settable fuse
- each relay can be set as Normally Open (NO) or Normally Closed (NC)
- compatible with most equipment to control their operation (chargers, converters….)
- comprehensive self-diagnostics performed at startup and every hour
- cell voltage and temperature simulation mode for system wide testing
- validate trigger settings
- validate relay wiring
- validate proper operation of devices controlled by the relay outputs
* requires the TBMS.shunt option
