Protecting against depletion of external battery

Protecting against depletion of external battery
Rechargeable Wildeye devices can be charged from an external battery pack, like our ACC-BP-LIION-15V77WH. You may wish to protect against depletion of the external battery system as per the following examples:
Lithium Battery - The external battery system is a Lithium battery pack that will not be damaged at low voltage but you wish to extend the operating life of the system to allow for more time to swap or charge the battery.
Strategies:
Use Window Charging to extend the life of the external lithium battery
Use General Battery saving Strategy using an Alarm to notify when battery is low.
SLA Battery - The external battery system is a sealed lead acid battery that can be damaged when the voltage falls below normal operating voltage.
Strategies:
Use Window Charging to extend the life of the external lithium battery
Wildeye’s built before 2025 will stop drawing power from the external battery if voltage drops below 10.8V, to save the SLA battery
Use General Battery saving Strategy using an Alarm to notify when battery is low.
Window Charging
Introduced in 2025, Wildeye’s contain a feature called Window Charging, which is designed to optimise the charging sequence when using an external battery pack. Normal charging keeps the internal battery continuously topped up, but this is not efficient when attached to an external battery. Window Charging allows the internal battery to nearly deplete over the course of weeks before charging from the external battery. The effect is less power draw over time from the external battery.
To switch a Wildeye into Window Charging mode, please contact Wildeye Support.
General Battery-saving Strategy using an Alarm
The Wildeye device manages its power usage and automatically enters sleep mode when it is not logging or uploading data. The vast majority of power is used when uploading data through the cellular IoT network.
A strategy to protect the power draw on the external battery system is to reduce the upload frequency of the Wildeye device when the voltage of the external battery system falls below a threshold.
All rechargeable Wildeye devices have a system input that can monitor external battery voltage. Alarms can be set on the external battery voltage input to alert a user to poor external battery condition, and the user can take action to reduce the upload frequency of the Wildeye device.
Where the user manages a fleet of Wildeye devices, they may wish to automate this process. This can be achieved by selecting an "Action" on the alarm. An alarm action can include changing the upload frequency of a Wildeye device. On the next upload after the alarm is triggered, the Wildeye device will be automatically sent a command to reduce its upload frequency, and therefore extend the last-remaining battery capacity.
