Scotty DC DC 12-48V 24-48V 12-36V
SCOTTY AI 3kW 24-48V CANbus Bi-directional DC to DC
Scotty AI is a bi-directional DC DC 12V to 48V and 24V to 48V that uses AI for auto-tuning. It is supported by a smartphone app and has over the air updates.
Scotty AI, developed by Safiery, is an advanced bi-directional DC-DC converter designed to optimize power management in vehicles and marine applications. It facilitates efficient charging and discharging between different voltage systems, such as 12V, 24V, 36V, and 48V, enhancing energy utilization and system flexibility. An international patent applies to the AI process.
Key Features:
- Artificial Intelligence (AI) Integration:
Scotty AI employs AI algorithms to automatically tune to the specific power curve of the connected alternator. This auto-tuning process occurs during an initial two-minute setup, allowing Scotty AI to adapt to various alternator types without manual configuration.
- Three Operating set points
When the auto-tuning process is initiated, Scotty AI uses AI to select 3 different voltage setpoints and auto-tunes at each one. These 3 setpoints are called “Soft” “Medium” and “Hard” modes of operation. “Soft” is the highest voltage with less load on the alternator, “Hard” is the lowest voltage setpoint. This is visible when observing the app and running the auto-tuning process. These modes are particularly useful when running at idle as solar back-up charging the high voltage lithium battery. The differences between these settings is unique to the vehicle engine but generally around 15% between the modes at idle.
- Alternator Protection:
Equipped with an accurate temperature sensor attached to the alternator housing, Scotty AI monitors temperature changes in real-time. The AI system analyzes the rate of temperature change alongside current and voltage parameters to detect out-of-range conditions. If such conditions are identified, Scotty AI adjusts its operating mode by shifting automatically from “Hard” to “Medium” to “Soft” thus preventing alternator overheating. The result is extending the alternator's lifespan.
- Bi-Directional Power Flow:
Scotty AI supports bi-directional power transfer, enabling it to charge a higher voltage battery (e.g., 48V) from a lower voltage source (e.g., 12V alternator) and supply power back to lower voltage loads when needed. This functionality is particularly beneficial for applications requiring multiple voltage levels, such as powering 12V accessories from a 48V battery bank.
- User-Friendly Interface:
The system is compatible with a smartphone app and an optional touch display, allowing users to monitor performance, adjust settings, and perform over-the-air firmware updates. This ensures the system remains up-to-date with the latest features and improvements.
By integrating AI-driven auto-tuning, real-time alternator protection, and versatile bi-directional power capabilities, Scotty AI enhances energy efficiency and reliability in various off-grid and mobile power scenarios.
Pros and Cons of connecting Scotty AI to CAN BMS battery?
- Firstly, the charge rate does not change whether CAN connected or not. It makes zero difference to the maximum charge rate whether on CAN or not.
- Scotty AI will read the Charge Current Limit (CCL) on a Victron compatible CAN BMS and stop charging when this goes to zero.
- It will also go to zero if the maximum voltage is met and stay at zero until the float voltage value is met. Its very simple.
- There is also a stop charge input wire that if connected to Victron Lynx BMS will stop charge when the input is open.
- For some brands of BMS with relay out for stop charge, this input wire can also be inverted.
In Summary, there is no advantage of CAN connection from a single Scotty AI with CAN BMS. However, if two are installed in parallel then they have to have a CAN connection to each other. Connecting to Battery CAN is optional.
Protects your Alternator
- Scotty AI DC DC uses the internal regulator of an alternator. Factory Supplied.
- Scotty AI DC DC does NOT modify or add to the alternator in any way.
- Scotty AI DC DC has an accurate temperature sensor that is placed on the alternator housing.
- When Scotty AI is running, the machine learning logs the alternator temperature operating range.
- AI monitors rate of change of temperature with current, time and voltage to identify out of range conditions.
- When out of range occurs, Scotty AI sets the mode back a level: Hard to Medium, Medium to Soft and Soft to Off.
Auto-tunes Alternator
No Programming Required
- Scotty AI DC DC does not need to know alternator or engine speed.
- The patented SCOTTY AI program maps the voltage and current with current rate of change to determine the optimal operating curve.
- The result is plug-n-play that your son or daughter can auto-tune from the Smartphone App.
Auto-tunes to Load Changes
- When an alternator gets hot, its efficiency and output level changes. External Alternator regulators find this hard to control.
- Scotty AI DC DC auto-tunes to the changing load and changing efficiency of the alternator.
Maximum Power At Idle
Solar Backup
- When the solar yield is poor and you need maximum DC DC power at Idle, just dial up "HARD" on the optional Touch Display or the Smartphone App.
- Your alternator is protected by AI. Should the temperature goes out of bounds then the setting will be automatically adjust back to medium.
- You just sit back and relax.
Scotty AI is on VE.CAN
Charges to CAN BMS
- Scotty AI runs on the 250 baud VE.CAN port together with compatible lithium batteries.
- It charges to the Charge Current Limit Set by the BMS
- If no BMS, then it charges to Max Voltage set on Smartphone App and storps charge either when voltage is reached or the "Stop Charge" wire nput is activated or deactivated.
Scotty AI is Bi-directional
Switches to supply 12V or 24V Loads
- Scotty AI will switch to supply 12V or 24V loads in 25ms.
- If there is a big winch or other 12V or 24V load, it will also switch even when the alternator is running. Simply turn "off" on the Smartphone App or Optional Touch Display. The full additional power is delivered to the starter battery in addition to the alternator power,
Scotty AI Meteor is Bi-Plug-n-play
12V - 24V or 36V or 48V Meteor Lithium
- Scotty Meteor AI will Plugs to front of Meteor train
- The CAN connection, Voltage and power bus connection are all internal.
- The Positive Plug that attaches to front of Scotty AI meteor has two Megafuses. One at 12V and the other at the Meteor Battery Power Supply.
