Features

TAO Monitor

touchscreen

TAO Monitor is a 3.5″ touchscreen that provides additional features:

displays battery and cell data as well as the state of relay outputs
displays historical data and event logs
provides access to all BMS data and functions via wifi (access point or station)
comprises a tool that generates graphs, analyzes measurements, and creates log histories
visualizes instantaneous and historical data on the internet over the life of the system (cloud)
CAN interface to control external equipment (standard and custom sentences)
integrated uninterruptible power supply (UPS) function with external battery (supplied)

Battery Data

battery voltage and temperature
battery input and output current (A/W)
state of charge (%, Ah used/Ah remaining)
state of health (%/actual capacity/internal resistance)
number of charge cycles
relay output state
last event

Cell Data

cell voltage and range
cell temperature and range
cell resistance and range
battery’s total internal resistance
battery’s average voltage and temperature

Measurement History

all battery and cells measurements are recorded
displays history over the preceding 30-day period
full lifetime measurement history can be displayed and analyzed using 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 output change of state
- SOC reset
- change of state (inside and outside defined ranges) is triggered
- cell resistance update
- CAN status
100 most recent events on the monitor
lifetime event history, analysis via connected device (phone, tablet, PC)

WiFi access to all measurements and EMS functions

any device with a browser can be connected to the EMS (no app to download)
battery and cell measurements
set all BMS parameters, ranges, and triggers
diagnostics and simulations
connects to an existing wifi network or creates its own access point and wifi network

Data and Event History Analysis (local and internet cloud access)

access data over local wifi or remotely via the internet* (* the monitor must be linked to a wifi network with an internet connection)
- instantaneous battery and cell measurements
- historical data and event log
standard graphs
flexible analysis capabilities to suit a wide array of needs

Flexible CAN Interface

CAN standard J1939
fully configurable CAN messages for connecting to most CAN-enabled equipment
sends data including battery voltage, temperature, state of charge, and state of health
sends charge and discharge parameters based on trigger state (voltage, temperature, or SOC range)
