Welcome to the Smart Engine Controller ® user manual.
This document describes the features and capabilities of the Smart Engine Controller, as well as gives examples of the use cases that reap the most benefits from the Smart Engine Controller.

Smart Engine Controller intelligently turns controllable engines on and off.
To put it simply, it tries to find the optimal state of the engines that:
• won't completely deplete the battery
• meets requested acceleration and speed
• is safe for engines
• has best fuel economy and battery charge rate

Smart Engine Controller only supports engines that are controlled by electronics, such as combustion and electric engines.
When enabled, Smart Engine Controller will immediately take control over all compatible engines and will start and shut them down as needed.
Smart Engine Controller supports between two and five controllable engines.
Smart Engine Controller allows the user to tune its settings for the usage of the electric motors.
This setting comes in the form of two sliders: "LO" and "HI" battery level, %.
• when battery level < LO, electric motor won't engage
• when battery level > HI, electric motor is preferred (but not guaranteed to be used)
• between LOW and HI, electric motor usage is determined by battery charge rate and other factors
Note: Smart Engine Controller will strive to keep battery level at or above "HI", utilizing the engines with attached alternators.

Intended use cases of the Smart Engine Controller:
Hybrid car with gas and electric engines
When battery level is "HI" or above, a more efficient electric engine will be used.
When accelerating, gas engine may be started to provide the best acceleration.
When battery level is below "HI", the gas engine with the alternator will be used to recharge the battery.
Car with two or more gas engines
When cruising, only one engine will be used.
When accelerating, more engines will be started to provide the best acceleration.
Car with a small and large engine
Depending on the speed, a single engine will be chosen to provide the best acceleration and fuel economy.
Stationary generator
When the battery reaches "HI" level, the gas engine will be turned off to save fuel.

Enjoy your optimal ride with the Smart Engine Controller!
