UPS System for Rugged Embedded Computers
temperatures from -40°C to +60°C (*+75°C)
is a Brown Out and Load Dump protection for Extended Reliability Operation. It is designed
to protect the rugged MPL embedded computer (PIP Family) from various input voltage failures. This includes reverse
polarity, over-voltage, load dump effects, and brown out (under voltage and power loss) failures.
The BOLERO system consists of the BOLERO-1 and the BOLERO-BATT-1.
The BOLERO-1 is responsible for detecting input voltage failures and switching to the battery, charging the battery,
and communicate with the host system. It consist of a load dump and polarity protection, a battery charger and a CPU
which controls the charger, the heater, and the state of the battery pack. To adapt the behavior of the BOLERO to the
environment and power requirements of the system, a small set of configurable non-volatile parameters are implemented.
The BOLERO-BATT-1 is the battery pack, designed with a fuel gauge, and a balancing and protecting circuit. The battery
is equipped with a heat foil to extend the operating temperature down to -40°C.
Since it is designed as plug-in module, the replacement of the battery pack does not require opening the PIP housing,
which makes maintenance easy. Included in the BOLERO-BATT-1 is a fuel gauge, giving accurate information about the
battery's state of charge. This information is not only available to the operating system, it is also visible via LEDs
on the battery pack front. A protective circuit prevents the battery pack from overcharging, deep discharge, over
current on charge and discharge, and short circuit. It also incorporates a cell balancing device which controls and
equalizes the voltage of each cell.
The driver for the BOLERO runs on different operating system and allows remote monitoring of the system power state via Ethernet.
The output power of the compact standard BOLERO solution is 10Wh, which is sufficient for 30 min. autonomy with an
average PIP power consumption of 20Watt, or 15 min. with 40Watt. The perfect solution for any PIP currently available.
