BATTERY & MAINTENANCE
Husky A200 is built for rugged, long-term use. Here are some steps that can be taken to
maintain and extend the life of the platform even further:
Charging
The battery shipped with Husky A200 may be charged off-board, or while still inside of Husky. If
charging while installed, you will need to open the access door to the battery area, and
disconnect the battery from its connector in the fuse panel. From there:
1.
Connect the DC output cable from the charger to the battery terminal connector.
2.
Plug the charger power cord into the charger and then into a wall receptacle.
3.
The POWER LED and CHARGING LED lights on the charger will illuminate.
4.
When battery is fully charged, the CHARGING LED light will turn off. Unplug the charger
from the wall, and then disconnect it from the battery.
The battery charger shipped with Clearpath Robotics’ lead-acid battery-powered products uses
a three-state charge cycle:
1.
A fast, high current initial charge, until the battery voltage reaches 29.6V.
2.
A topping charge, during which the battery charges at 29.6V constant voltage until the
current decreases to 500 mA.
3.
A precision float charge, during which the battery voltage is held at 27.6V. This mode
allows the charger to remain connected to the battery during periods of non-use,
keeping it in a state of full charge. When in this mode, the CHARGING LED will be off.
Battery Care
Husky’s power supply is a sealed 24 V lead acid battery pack (VRLA), providing 20 ampere-hours
of charge. To maximize the lifetime of the battery, recharge immediately after use, and keep
charged to prevent loss in capacity. Battery life expectancy is shown in Table 4and shelf charge
retention in Table 5.
