Battery

Some device types feature an integrated battery (lithium-polymer).

The integrated battery allows it to send logged CAN and position data via the cellular radio interface even if the power supply from the main plug connector is interrupted. The device is not designed for permanent battery operation.

On delivery, the integrated battery is charged by approx. 30%. Before you use the device, charge the battery fully. See Charging the Battery.

A fully charged battery can back up a power failure of approx. 1.5 hours (@ 20°C battery temperature), ensuring active operation of the device.

The following examples provide an overview of the battery runtimes in various application cases.

Example 1:

The rechargeable battery integrated is charged to 100% and the device is permanently switched on and online. The device transmits one file per minute.

The battery runtime is approx. 2 hours.

Example 2:

The integrated battery is charged by 100% and the device is permanently in Sleep mode.
The device switches on cyclically every 24 hours and is online for 5 minutes to transmit the current position and certain internal device parameters. Then the device automatically switches back to Sleep mode.

The battery runtime is approx. 14 days.

Example 3:

The integrated battery is charged by 100% and the device is permanently in Sleep mode.
The device goes online only once, triggered by the acceleration sensor, and transmits the current position (theft monitoring without external power supply).

The battery runtime (operational readiness) is 70 days.

The values stated in the examples can deviate depending on the use purpose, the setup conditions (@ 20°C battery temperature) and the configured device variable GO TO SLEEP VOLTAGE, see Important device variables.

Note on the integrated battery

• The integrated battery is charged using the power supply via terminal 30 and charging is only possible in a limited temperature range of:
  0 °C … +45 °C (+32 °F … +113 °F)

• Battery operation of the device is only possible in a limited temperature range of:
  -20 °C … +60 °C (-4 °F … +140 °F)

Note the following information about use of the integrated battery

• The integrated battery has a limited service life.
  After 500 charging cycles, contact the Proemion service to replace the integrated battery, see Chapter Service and Support.
  The number of charging cycles can be read out via the BATTERY - CYCLE COUNT device variable. See Battery.

• Perform three complete charging and discharging cycles to achieve the full performance capability of the integrated battery.

• During battery operation, it is not possible to use the digital output.
