15.4. Firmware v2.7.0 Enhancements

Firmware v2.7.0 for ATevo brings enhanced new features. Click on each of the toggles below to learn more:

Alarm Triggers

The Evo charger always had the user configurable “Common Alarm”. New alarms named “High Priority Alarm” and “Low Priority Alarm” are now available to a user who wishes to further customize alarm priority. These alarms can be configured to close a relay on an AUX I/O and are also readable over SCADA. Configuration is enhanced to accommodate selecting the triggers for these new alarms in the same menu that the common alarm is configured.

Firmware prior to v2.7.0 navigated directly to common alarm configuration. Firmware v2.7.0 now navigates to a menu that allows a user to select one of the three “aggregate” alarms to configure. The lower right display shown is typical when “Common Alarm” has been selected. “High Priority Alarm” and “Low Priority Alarm” displays are similar. Also new in v2.7.0 is that alarms are listed in alphabetical order. In addition, alarm types that depend on optional hardware are only displayed if the respective option is installed. Examples are “Battery overtemp” and “Battery temp probe fail”; these are visible only if a battery temperature probe is installed and enabled.

Disable Equalize

Disables the EQUALIZE output voltage mode which attempts to equalize the voltage among battery cells. This action can be triggered by either a binary or analog input. An example use-case for this feature would be when an aux input connected to a hydrogen sensor fires a 1% Hydrogen Alarm, this input can disable the EQUALIZE charging. This is presented as a new selection under the AUX INPUTS menu as an “Action” for either a binary input or an analog input, as seen in the figure below.

Menu Changes

For clarification and to accommodate the new features mentioned above.
