Features: TAO Monitor
TAO Monitor is a 3.5″ touchscreen that extends the features of the TAO BMS:
- display battery and cell measures + state of relays outputs
- display historical measures and events log
- access to all BMS data and functions via WiFi (access point or station)
- graph and analysis tool to exploit measure and log history
- view live and historical data on Internet for the full life of the system (Cloud)
- CAN interface to command external equipment (standard and custom sentences)
- integrated UPS (Uninterruptible Power Supply) function with external battery (supplied)
Battery measures
- battery voltage and temperature
- current in and out of the battery (A / W)
- state of charge (%, Ah used / Ah left)
- state of health (% / actual capacity / internal resistance)
- number of charge cycles
- relays output state
- last event
Cell measures
- cells voltage and range
- cells temperature and range
- cells resistance and range
- battery total internal resistance
- battery average voltage and temperature
Measures history
- all battery and cells measures are recorded
- display the last 30 days of history
- full lifetime measure history can be displayed and analysed with a browser (phone, tablet or PC connected by WiFi)
Events history
- battery, BMS and monitor events are recorded:
- BMS power-up, diagnostics fault…
- monitor power-up, connection to BMS, backup battery, shutdown…
- balancing activity
- relay outputs change of state
- SOC reset
- triggers change of state (in and out of defined ranges)
- cell resistance update
- CAN status
- last 100 events on the monitor
- lifetime events history and analysis on connected device (phone, tablet, PC)
WiFi access to all measures and BMS functions
- any device with a browser can connect to the BMS (no need to download an App)
- battery and cells measures
- set all BMS parameters, ranges and triggers
- diagnostics and simulations
- connects to existing WiFi network or creates it’s own access point and WiFi network
Measures and events history analysis (local and Internet Cloud access)
- access data on local WiFi or remotely via Internet* (* the monitor must be connected to a WiFi network with Internet connection)
- live battery and cells measures
- historical data and events log
- standard graphs
- flexible analysis capabilities to suit a wide array of needs

Flexible CAN interface
- CAN standard J1939
- fully configurable CAN messages to connect to most CAN enabled equipment
- sends battery voltage, temperature, state of charge, state of health…
- sends charge and discharge parameters based on trigger state (voltage, temperature or SOC range)
