Victron Energy VE.Bus bms

The vE.Bus bms from victron Energy (mpn) is a battery management system perfectly designed for victrons lithium batteries with vE.Bus connection, but can also work with equivalent batteries from other manufacturers. Each individual cell of a LiFePO4 battery must be protected against overvoltage, undervoltage and overtemperature. This is exactly the task performed by the ve.bus bms. The product is suitable for protecting 12v, 24v and 48v battery banks and operates over an operating voltage range of 9 - 70 vDC. vE-BUS bms in interaction with victrons LiFePO4 batteries victron LiFePO4 batteries have built-in cell balancing, temperature and voltage control (English abbreviation: btv) They are connected to the vE.Bus bms via two m8 circular connector cable sets. The BTvs of several batteries can be daisy-chained together. Up to five batteries can be connected in parallel and up to four batteries in series (BTvs are simply daisy-chained), so that a 48 v battery bank with up to 1500 Ah can be assembled. For more details, please refer to the technical documentation of our LiFePO4 battery. Core tasks of the victron vE.Bus bms Switching off or disconnecting loads in the event of imminent undervoltage Reduce charge current in case of imminent cell overvoltage or overtemperature (only for vE.Bus products) Switching off or disconnecting battery chargers in the event of an imminent cell overvoltage or excess temperature communicates with all vE.Bus products The vE.Bus bms can be connected to a MultiPlus, Quattro or Phoenix inverter device. The connection is made via a standard rj45 UTP cable. The vE.Bus bms in interaction with other batteries LiFePO4 batteries from other manufacturers can be controlled with the device as follows: "Load Disconnect" The Load Disconnect output is normally high and is set to free floating when cell undervoltage is imminent. Maximum current: 2A. The Load Disconnect output can be used to control the following functions: remote on/off switching of a load and/or remote on/off switching of an electronic load switch (BatteryProtect) ) "Charge Disconnect" (charge disconnect) The Charge Disconnect output is normally high and will free float when a cell overvoltage or overtemperature is imminent. Maximum current: 10 mA. The Charge Disconnect output can be used to control the following functions: remote on/off switching of a charger and/or a Cyrix-Li charger relay and/or a Cyrix-Li-ct battery coupler Scope of delivery: 1x victron Energy bms300200000 vE.Bus bms Battery Management System 1x user manual

The minibms from Victron Energy (mpn bms400100000) is a simple and cost-effective alternative to the VE.Bus bms and can replace the VE.Bus bms in several applications. Important exceptions here are VE.Bus devices such as the Multiplus and Quattro series, because the minibms does not have its own VE.Bus port, unlike the VE.Bus bms. The minibms is designed for use with Victron Smart liFePo4 batteries with m8 round connector and has two outputs similar to the ve.bus bms. The operating voltage range is 9 - 70 VDC. Core tasks of the Victron minibms Switching off or disconnecting loads in the event of imminent undervoltage Switching off or disconnecting battery chargers in the event of imminent cell overvoltage or overtemperature "load Disconnect" (disconnect load) The "load Disconnect" output is normally high and is set to "free floating" when a cell undervoltage is imminent. Maximum current: 2A. The load Disconnect output can be used to control the following functions: remote on/off switching of a load and/or remote on/off switching of an electronic load switch (BatteryProtect) ) "Charge Disconnect" (charge disconnect) The Charge Disconnect output is normally high and will free float when a cell overvoltage or overtemperature is imminent. Maximum current: 10 mA. The Charge Disconnect output can be used to control the following functions: remote on/off switching of a charger and/or a Cyrix-li charger relay and/or a Cyrix-li-ct battery coupler The "System on/off" input The input "System on/off" controls both outputs. If it is off, both outputs are switched to "free floating". The loads and chargers are therefore switched off. The "System on/off" input has two connections: Remote l and Remote h. Between l and h, a remote on/off switch or a relay contact can be connected. Alternatively, terminal h can be connected to a battery positive terminal or l to a battery negative terminal scope of delivery: 1x Victron Energy bms400100000 minibms 1x instruction manual

The Smart bms 12/200 from Victron Energy (mpn bms210055000) for smart Victron lithium iron phosphate (LiFePO4) batteries is specifically designed for 12v systems with a 12v alternator. It combines a current limiter, battery coupler and battery monitor in a robust and compact solution. The Smart bms 12/200 monitors and protects each battery cell individually within the battery (or battery bank) and disconnects from the alternator, charging sources or DC loads in the event of low/high battery voltage or over temperature. The dedicated alternator connection provides current limiting and one-way traffic from the alternator to the battery, allowing alternators of any size (and starter batteries) to be safely connected to the Smart Lithium battery and protecting the starter battery from excessive discharge. The bms is equipped with Bluetooth for monitoring and configuration, a remote on / off port to turn off the bms (and the system) via a switch and a pre-alarm contact and give a warning signal u before the bms disconnects the connection between the battery and the system. Features Protection of the starter battery Alternator and battery protection Load / battery charger output / input (power supply socket SYSTEM+) Lithium-ion battery protection Load disconnect, pre-alarm and charge disconnect output Remote on/off output, also configurable as system on/off Alternator and battery protection The input current is electronically limited to approx. 90% of the fuse value. A 100a fuse, for example, therefore limits the input current to about 90a. Choosing the right fuse will help protect the LFP battery from excessive charging current (important in the case of a low capacity LFP battery). It also protects the alternator from overloading in the case of a high capacity LFP battery bank (most 12v alternators will overheat and fail if left running at maximum output power for more than 5 minutes). Load/Battery Charger Output/Input (SYSTEM+ Power Supply Bay) this power supply jack can be used to either charge or discharge the LFP battery (i.e., via a charger or inverter) with a maximum continuous current of 200a in either direction. Can also be used as a load output, allowing DC loads to be connected directly to this connector. The connection is short circuit proof with a peak discharge current of 400a. The smart bms ensures that battery discharge is disabled when cell undervoltage is imminent. It allows charging via this port, but no charging algorithm can be applied internally. Lithium-ion battery protection excessive input voltages and transients are regulated down to a safe level. The smart bms stops charging in case of cell overvoltage or overtemperature. It has three outputs: /p> Load disconnect output: The load output can be used to control the remote on/off of a battery protector, inverter, DC/DC converter or other loads. Pre-alarm output: The pre-alarm output can be used as a warning when the battery voltage is low and it will trip just before the load disconnect output is deactivated due to cell undervoltage. It can be used to control a relay, led or buzzer. It can be configured as a continuous or intermittent signal. Charger disconnect output: The charger output is normally high and will free float if there is a threat of cell overvoltage or overtemperature. The Charger output can be used for control to remotely turn on/off a charger, a Cyrix-Li charger relay, or a Cyrix-Li-Ct battery coupler. A non-inverting or inverting on/off cable may be required. Remote on/off, also configurable as system on/off The remote on/off output controls charging via the alternator, while the bms functionality remains active regardless of the remote on/off state. The remote can also be used as a system on/off switch. This can be configured with VictronConnect. Technical data Max. Charging current, alternator connection: 100a (with 125A fuse) Max.
