BeWired+ (B4-MIOT-MR BTW) Externally-Powered

BeWired+ is the 4th generation of the BeWired powered (wired) version of BeWhere's low-power 5G asset tracking device family. It comes with a wiring harness to connect to external power and/or external sensors. It has an ignition wire (power sense) option for capturing engine runtime.​

The BeWired+ maintains our existing suite of sensors and further incorporates a Wi-Fi feature for location service when indoors. It also includes a Bluetooth transceiver that functions as a BLE Gateway reader, enabling the integration of BLE Beacon Tags and Sensors. Furthermore, the device is housed in a ruggedized enclosure, enhanced to IP69K standards.

Battery Insights

This document describes the product specifications of rechargeable Li-polymer battery used with BeWhere’s BeSol+ asset tracker.

Characteristics

Item Spec Remark
Nominal Capacity​ 2700mAh@ 0.2 C5A Discharge​ Nominal capacity refers to the capacity of 0.2C5A​ discharge with 3.0V cut-off voltage, application cut-off voltage at 3.5V​
Cycle Life ~700 Times One cycle refer to one charge period and then one​ discharge period.​ The cycle life is the cycle times when the discharge capacity is about 70% of the rated capacity.​
Standard Charge 0.2C5A 0.2C5A CC (constant current) charge to Max Charge voltage 4.2V,then CV(constant voltage 4.2V) charge current decline to ≤0.01C.
Standard Discharge 0.2C5A 0.2C5A CC (constant current discharge to discharge cut-off)
Operating Temperature Charge*: 0 ℃~ +45℃
Discharge**: -20℃~ +60℃
Over Charge/Discharge Protection The battery pack has a protective circuit module to prevent over-charge/discharge for safety.

⚡ Charging Current by Input Voltage

Input Voltage Max Charging Current
12V 250 mA
24V 125 mA
40V 75 mA

⏱️ Estimated Charge Time (Assuming 85% Efficiency)

Input Voltage Effective Charge Current Estimated Charge Time
12V ~210 mA ~13 hours
24V ~106 mA ~25 hours
40V ~64 mA ~42 hours

These are approximate values and can vary based on: - Ambient temperature (charging disabled < 0°C or > 45°C) - Device usage during charging - Battery wear or health

Notes

- The actual charge current to the battery is regulated by internal circuitry and may be lower due to safety and thermal constraints.
- *Recharging circuit has charge-protection above 45℃ for safety compliance and recharge current declines 
when below freezing point.
- **Based on bench test/field test data and device has performed outside specifications 
up to -35 ℃ without reducing operating performance

🔒 Safety Notes

  • Charging is disabled below 0°C or above 45°C.
  • Battery is protected by overcharge and discharge safety circuits.
  • Charge time is managed by an internal smart controller to optimize battery life and safety.

Color Type Application Features/Functionality
Pink Input Power Input Supplies primary DC power to the device from a vehicle battery or external source (e.g., 12V/24V up to 120VDC systems). Supports wide voltage range from 7.5v to 120V for automotive/industrial use; device enters sleep mode if voltage drops below threshold.Voltage is continuously monitored via internal ADC and reported in real-time or periodic logs as external battery voltage source for remote diagnostics, low-battery alerts, and fleet management insights.
Black Common Ground GND Provides common reference ground for all circuits. Essential for stable operation; connects to vehicle chassis or battery negative to complete power circuits and prevent electrical noise. (Not an input, but foundational for all features.)
Grey Input IGNITION Detects vehicle ignition status (ON/OFF) by monitoring switched power from the ignition key or accessory circuit. Triggers "engine on" events for real-time tracking activation, engine hour logging, geofencing alerts, and power-saving modes (e.g., deep sleep when OFF to conserve battery).
White Input ONE WIRE Interfaces with 1-Wire protocol devices (e.g., Dallas DS18B20 temperature sensors). Enables remote temperature monitoring (e.g., cargo/refrigerated loads), driver authentication (via iButton touch), or asset ID reading. Supports multi-device daisy-chaining for expanded sensing.
Blue Input 12V ANALOG Reads variable analog voltage signals (0-12V) from sensors like fuel gauges, battery monitors, or pressure transducers. Provides proportional data for metrics such as fuel level percentage, voltage trends, or custom analog inputs; often used for fleet management dashboards and predictive maintenance alerts.
Yellow Input SWITCH SENSOR 2 Acts as a digital switch input (positive or negative trigger configurable). Monitors binary states like door/trunk open/close, cargo tamper, or auxiliary alarms. Triggers immediate events, location reports, or immobilization commands upon state change.
Red Input SWITCH SENSOR 1 Similar to Yellow
