BeSol+ (B4-MIOT-MR BSP) Solar-Powered Device

BeSol+ is an upmarket device offering based on one of our most popular low-power 5G asset trackers, the BeSol. It comes with a larger rechargeable battery and solar panel to provide higher frequency updates for use-cases that demand it.​

The BeSol+ maintains our existing suite of sensors and further incorporates indoor location using Wi-Fi/BLE 5.2. 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​ 7000mAh@ 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 ~500 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.

Notes

- *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
