System Profiles
Charger Profiles Tab–all fields on this tab are editable
Charger ID – This field is factory-set to be blank. You can change or set it on the “System Profile” and “Dashboard” screens.
Vehicle ID – Displays the ID of the vehicle that you pair with the charger (if applicable). The Vehicle ID is factory-set to be blank. You can set or change the Vehicle ID on the “System Profile” and “Dashboard” screens.
DC Cable Gauge (AWG) – The gauge of the DC cable in American Wire Gauge (AWG). This field helps user correctly compensate for the voltage drop of the DC cable.
DC Cable Length (feet) – The length of the DC cable in feet [one direction only, not the sum of the length of both the positive (+) and negative (-) wires]. Use this field to correctly compensate for the voltage drop of the DC cable.
On Board check box – Features a “check” for On-Board and a “unchecked” box for Off-Board.
On-Board chargers are made to mount on electric vehicles/equipment. When you connect the DC output to a battery pack, a charge cycle automatically starts after you connect the plug to AC power. Remember to wait for a safe period of time to elapse after the successful completion of the previous charge cycle.
NOTE: Disconnecting the DC output from the battery pack IS NOT A REQUIREMENT to automatically start a new charge cycle.
Off-Board chargers are for shelf or portable applications. As you connect the AC input plug to live AC power, a new charge cycle automatically starts after you connect the DC output to a battery pack. Disconnecting and reconnecting AC power while the DC output remains connected to a battery pack WILL NOT automatically start a new charge cycle.
NOTE: Disconnecting the DC output from the battery pack IS NOT A REQUIREMENT to automatically start a new charge cycle.
On-board configuration- you can use it in a shelf or portable application where the DC output connector/plug connects and disconnects from the vehicle. But when configuring a charger as Off-Board, you should mount it on a vehicle with the DC output permanently connecting to the battery pack. This is because the charger will not automatically start a new charge cycle when you apply AC power to the charger.
Auto Voltage Profile – Only present on charger models that support Auto Voltage Mode. See the “Auto Voltage Mode” section below for details.
Cloud Profiles Tab
System profiles available for download from the ChargerConnect Cloud.
Download system profiles from the Cloud to your smart phone or tablet via the green arrow buttons.
Blue question mark buttons provide detailed list of the system profiles.
Device Profiles Tab
Lists of all system profiles available on your smart phone or tablet (device).
Upload a system profile that resides on your smart phone or tablet to the connected charger via the green arrow button.
Details of the system profiles can be found under the blue question mark buttons.
Delete system profiles that reside on your smart phone or tablet (device) via the red trash can button.
Auto Voltage Mode
Some Summit Series II charger models support automatic multi-voltage DC charging (Auto Voltage Mode). Auto Voltage Mode provides automatic DC output voltage detection and adjustment so that battery packs of nominal 48V and 36V (650W 48V, 36V, and 48-36V models) or nominal 48V, 36V, and 24V (all 1050W models) will charge with a single charger. No configuration changes are necessary when switching between battery packs of different nominal voltages.
When the connected charger model supports Auto Voltage Mode, the “System Profile” screen will include an “Auto Profile” selection box, which provides the following three (3) options:
OFF: Single voltage mode – you MUST ensure that the nominal DC voltage of the “Active Battery Profile” for the charger matches the nominal DC voltage of the connected battery pack.
PER VOLTAGE PROFILES
650W 48V, 36V, and 48-36V models: You can assign different battery profiles for 48V and 36V. The charger will automatically select the proper battery profile per the battery pack that you connect. You can use this mode when the charger will be charging 48V and 36V nominal battery packs where the battery packs are of different types and/or capacities so using the “Scalable Profile” mode is not appropriate.
All 1050W models: You can assign a battery profile for 48V, and a different battery profile for 36V and 24V. The charger automatically selects the proper battery profile contingent on the battery pack you connect. You can use this mode primarily when the charger will be charging 48V, 36V, and 24V nominal battery packs [or any combination of two (2) of these voltages] where the battery packs are of different types and/or capacities so using the “Scalable Profile” mode is not appropriate.
SCALABLE PROFILE
650W 48V, 36V, and 48-36V models: the nominal DC voltage of the “Active Battery Profile” will automatically scale to 48V or 36V based on the connected battery pack.
All 1050W models: the nominal DC voltage of the “Active Battery Profile” will automatically scale to 48V, 36V, or 24V based on the connected battery pack.
NOTE: Under “Per Voltage Profiles” or “Scalable Profile” mode, if you set the “Auto Profile” selection box to “Off”, you MUST ensure that the nominal DC voltage of the “Active Battery Profile” for the charger matches the nominal DC voltage of the connected battery pack via the “Battery Profiles” screen.
When Auto Voltage Mode is active (either “Per Voltage Profiles” or “Scalable Profile”) the “Dashboard” screen shows “Auto Battery Voltage Detection” as a status percentage and the “Detected Battery Pack Voltage” (see the “Dashboard” section).
Battery Profile
Charger Profiles Tab
Battery profiles that are available on the connected charger.
Click green check mark to set the “Active Battery Profile”.
Descriptions of the battery profiles (blue question mark).
See the “Battery Profile Quick Reference” section below for info about the most common profiles.
Cloud Profiles Tab
Profiles available for download from the ChargerConnect Cloud.
Download profiles to smart phone or tablet via the green arrow buttons.
Device Profiles Tab
Battery profiles available on your smart phone or tablet.
Upload battery profiles that reside on your smart phone or tablet (device) to the connected charger via the green arrow buttons
Select a “Profile Slot Number”. Summit Series II chargers can store up to 20 battery profiles locally in slots which are numbered 0-19. You can store a profile in an empty slot or a used slot. If you select a used slot, the battery profile will overwrite the existing profile.
Please note that when you upload a battery profile to the connected charger, it automatically becomes the Active profile on the charger. Delete battery profiles that reside on your smart phone or tablet (device) via the red trash can button.
