Exploring Electric Superchargers: Energy Storage & Performance Concerns

In summary, the conversation discusses the potential use and challenges of electric superchargers in automotive vehicles. The main issue is energy storage, as electric superchargers require their own power source and motor to drive the compressor. This can make them less efficient compared to other options such as mechanically coupling to the engine or using electric-assist turbos. Some prototypes and trucks have used electric superchargers, but their best use may be to quickly spool up a larger turbo. The conversation also briefly mentions the development of a fuel/O2 gas powered turbo system.

Does anyone here have any experience with electric superchargers? From the limited information I've read on the Internet, it seems energy storage is the biggest issue with them. For one, the average automotive vehicle tends to have a battery with too low of a voltage. Also, the motors that provide enough compression are too heavy/big.

The limiting factor goes back to power requirements- a lot of power is required to compress air at the pressure and flow rate required to run an engine. Paired with the fact that an electric supercharger requires its own energy storage and motor to drive the compressor, it's really a losing proposition compared to mechanically coupling to the engine either through belt drive or exhaust turbine drive (as in a turbocharger).

Audi has prototypes and some volvo trucks run a motor/generator instead of mechanical linking as in a turbo compound engine.

In short bursts, they can function at low boost levels. Probably their best use though would be to quickly spool up a larger turbo. Of course, electric-assist turbos do the same thing. :biggrin:

I am working on a fuel/O2 gas powered turbo system. Any thoughts?

I'm thinking that has nothing to do with this thread's topic...
 

1. What are electric superchargers?

Electric superchargers are devices that use an electric motor to compress air and increase the oxygen intake in an engine. This results in improved engine performance and can increase horsepower and torque.

2. How do electric superchargers work?

Electric superchargers work by using a small electric motor to spin a compressor wheel, which then compresses the air that is being sucked into the engine. This compressed air is then forced into the engine, resulting in better combustion and increased power.

3. What are the benefits of using an electric supercharger?

The main benefit of using an electric supercharger is increased engine performance. It can also improve fuel efficiency by allowing the engine to burn fuel more efficiently. Additionally, electric superchargers are typically more compact and easier to install compared to traditional mechanical superchargers.

4. Are electric superchargers better than traditional mechanical superchargers?

This is a subjective question, as it ultimately depends on personal preference and the specific needs of the vehicle. However, electric superchargers can offer some advantages over mechanical superchargers, such as quicker response time and improved fuel efficiency.

5. Can electric superchargers be used on any type of engine?

Electric superchargers can be used on most types of engines, including gasoline, diesel, and even hybrid engines. However, it is important to ensure that the electric supercharger is compatible with the specific engine and vehicle before installation.
