Wireless Bluetooth COBOX Watt meter 36V/48V Power Analyzer for Android Smart-phones

◀ ▶

Wireless Bluetooth COBOX Wattmeter is an electric bike computer that streams measured and calculated electrical parameters right to your Android smartphone via wireless Bluetooth protocol at operating distance of up to 80 meters.

A cyclist can instantly get live electrical parameters to their Android smartphone, together with a GPS location on the map, trip and velocity data. Or, alternatively, one can simply use it with other DC electrical devices, such as RC toys, solar panels, Quadrocoper, electric vehicle, battery testing, etc.

The Android smartphone samples the values once per second and records them to the log file for post-processing and further analysis.

To be able to present the data on an Android smart phone, one has to install the COBOXWmeter application on that smartphone (Android version 4.3 and above).

The COBOXWmeter application features three different screens:

The Dashboard screen displays:

Main data (Speed, Distance, Ah, V, Vmin, A and Amax)
State of GPS signal, wireless Bluetooth COBOXWmeter connection state and trace log state
Speed gauge

The Indicators screen displays:

All electrical data from COBOXWmeter
Distance, speed and maximum speed data
COBOXWmeter power up time (Trip Time)
Power Time. Duration of battery discharging – running time on electric power
Regeneration – NEW model of COBOXWmeter – COMING SOON
Two different temperatures
Two different cadences
GPS Fix – The number of GPS satellites fixed versus satellites available

The Map screen:

Displays your ride on a Google map

Features of Wireless Bluetooth COBOX Wattmeter – Power Analyzer for Android smart phones:

COBOX Wattmeter/36V handles: maximal Voltage Vmax=55V, maximal Current Imax=60A
COBOX Wattmeter/36V starts to work at Vmin= 6,5 V
COBOX Wattmeter/48V handles: maximal Voltage Vmax=60V, maximal Current Imax= 60A
COBOX Wattmeter/48V starts to work at Vmin= 30 V
Output for smart phone USB charging
· Powerful 8 bit microcontroller

COBOX Wattmeter – Power Analyzer measures Current, Voltage, Temperature, Cadence and uses these parameters to calculate the Power, maximum Power, minimum Voltage, maximum Current and Battery consumption in Ah and Wh.
Android smartphone displays all real-time electrical data, GPS position, GPS Speed and shows your trip on a map.
Real time calculating of maximum power, minimal voltage, maximal Current and battery capacity used
Records all data to the Android smartphone with 1 second granularity- that is all the data are sampled and recorded once every second in to the data log located on the smartphone’s internal memory.
Trace logs not older than 24 hours can be appended when the COBOX Wmeter Android application is powered on.
Factory calibration is stored in EPROM on COBOX Wattmeter – Power Analyzer device
COBOX Wattmeter can easily be manually calibrated (Voltage and Current) in order to display accurate measurements.
When the battery drains out and COBOX Wattmeter stops working, the last electrical data on Android smartphone can be recalled, provided it was connected to the device and COBOXWmeter application is running on the smartphone.
Regeneration Current (new version of COBOXWmeter – SOON AVAILABLE) - Indicates the current value of electrical current generated by means of regeneration (e.g. at breaking of the vehicle).

Wireless Bluetooth COBOX Wattmeter can be used in difference ways:

Trip information record
Display real-time all electrical data
Display real-time temperature and Cadence
Logging of all data for post processing and further analysis
Battery discharging and charging health monitor
Power system diagnostic tool (to find faults or errors in the power system)

BENEFITS of Wireless Bluetooth COBOX Wattmeter:

Wireless Bluetooth COBOX Wattmeter – Power Analyzer provides all information about electrical powered devices such as electric bike, eBike, EV, Solar panels, RC toys, Quadrocopter, Battery monitoring…

This information helps:
