|Battery Management Unit
The Battery Management and Charging unit (BMU) was developed with the functionality of providing a zinc-air battery-‘managing’ device - making use of constant current charging. Therefor this unit is also well-suited for any other battery technology requiring constant current charging.
The main functionality of the ‘managing’ device is the controlling/managing of the amount of ampere-hours that was delivered from the battery, as well as managing the charging of the battery back to the correct level. The BMU software makes use of a menu structure allowing the user to define certain operating conditions for the battery.
The keypad user interface
is quite simple to use. The left and right buttons are used to scroll
through the menu settings, the up and down buttons are then implemented
to adjust the various control settings accordingly.
