Get To Know About Some Negative Aspects Of An Electric Motor

December 15, 2022

Concerns regarding electric motors are still prevalent. We wish to dispel stereotypes and demonstrate the benefits. For many years, internal combustion engines have been reliable. Electric motors, on the other hand, are theoretically far more efficient, and the only major drawback right now is the energy source. A rechargeable battery typically provides the voltage needed for an electric motor on a boat.

Below are some negative aspects that impact the working of an electric motor.

  • Energy range and density
  • Electric boat motor acquisition costs
  • Environmental effects of battery production
  • Boat battery weight
  • Charging time

1. Energy Range And Density

Compared to a 12v lithium ion battery, gasoline has 100 times more energy density. E-motor efficiency is ten times greater. The greatest range is harmed and the energy density is effectively ten times worse.

Therefore, a Marine battery‘s weight and acquisition costs are crucial factors, particularly for larger motors or long-term gliding. Therefore, it makes sense to calculate the battery capacity in the best possible way for the intended driving time and power.

This drawback is easily avoidable by carefully organizing your routes and excursions. Electricity is normally accessible at every jetty or port. If you use your boat during the day, it can be powered up at the dock overnight and be completely functional by morning.

While it is a drawback because you either need more space in your boat for batteries or have a restricted range, fortunately, an electric motor takes up substantially less space than the main engine with a combustion engine. In our experience, most conversions to electric motors have not resulted in a range of issues.

2. Electric Boat Motor Acquisition Costs

The battery’s procurement costs rise when its capacity is increased. They account for a sizable amount of an electric motor system’s overall cost. When it comes to tiny and medium-sized engines, an electric motor makes sense. In comparison to the combustion engine, the costs are comparable.

The energy density of batteries has already increased significantly in recent decades, at a rate of 5 to 8% annually. Every year, investments of many billions of euros are made to advance development. The main automakers are the key stakeholders, and the majority of them have clean energy transition plans by 2030.

It will primarily benefit boat owners, and the idea of electric motors and batteries will grow increasingly appealing. At the moment, batteries cost €500 instead of €1,000 per kilowatt hour. This development will be cheaper and substantially more profitable in the next several years!

There is a great deal of research being done on using hydrogen as an energy source in addition to new kinds of batteries. Similar to ordinary fuel, hydrogen promises a great range and quick refueling. But at the moment, fuel cell costs are not yet competitive. We’re still thrilled and will lead the way! And even more crucial: We’ll keep you abreast of the most recent technological developments with our newsletter!

4. Environmental Effects Of Battery Production

Manufacturing and shipping 12 volt battery systems and electric motors to Germany is required. In addition to the consumption of resources, production results in CO2 emissions. The vast majority of the engines will likewise be made in Asia before being imported.

We place a high value on highlighting this fact and favor suppliers who have a smaller carbon impact. You can use the special CO2 calculator we’ve created on our website to thoroughly compute the CO2 balance and determine when an electric motor is more environmentally friendly.

The media frequently reports on the manufacture of batteries and the environmental harm that results, primarily as a result of e-cars. Soon, there will be a thorough article about the show and its emissions.

For each kWh of battery, around 125 kg of CO2 is produced. This is equivalent to emitting about 60 liters of gasoline. You can easily determine the consumption, after which it is worthwhile to switch to a battery-electric vehicle, depending on the size of the storm. Within the first year, typically!

4. Boat Battery Weight

Larger lead battery systems are inconvenient or expensive when using lithium. Only those who drive a lot should invest in lithium batteries. You drive frequently, making about 40 trips annually, each of which fully drains the battery. However, even if you only drive sometimes, you may still benefit from all the positive aspects of an electric motor that cannot be compared to the value of money.

AGM batteries are typically roughly three times heavier. The tank typically flies out of the boat after conversion, providing the ship with greater room and a specific frame for weight. Specifically for sailing ships, which occasionally require additional weight in the keel, it is crucial to construct the batteries as efficiently as possible. Only then, it is advantageous to have a little bit more weight in the boat.

5. Charging Time

The battery and inverter charger affect how long it takes to fully charge. Hydrogen, diesel, or gasoline all provide substantially faster refueling times for boats. This appears to be yet another drawback of an electric boat drive. Boaters, however, only move after stopping for a while.

The flexibility of e-mobility is developing as is the rate at which battery systems charge. Tesla’s Supercharger, which charges a car battery up to 80% in just 30 minutes, exemplifies how it’s done. Longer voyages will be hassle-free thanks to an increase in the number of charging stations on the water.

We will be pleased to locate a suitable charging method or an electric drive with the proper range for your boat based on your demands. However, not every application or piece of material warrants the use of an electric motor.

Conclusion: Evaluation Of Combustion And Electric Engines

Each variation has a distinct advantage. An electric engine is exactly what you need if you want to paddle your boat around the lake quietly, preserve the ecology and your local waters, or simply adore advancement. Almost Everything supports electromobility, particularly small and medium-sized engines.

You could currently be better suited with a traditional nitro engine if you own a boat that needs a powerful planning engine, primarily due to the battery system.

The sometimes reduced acquisition costs for larger drive systems and the longer range and driving time offered by large engines are reasons in favor of combustion engines. Because everything is feasible, electric motors are in the last premium sector in this field. Particularly pricey are planning boat battery systems. However, electric motors are just as powerful and are perfect for gliding! There is no other option, particularly on lakes where e-boats are the only permitted vessels.

An electric motor has the benefits of being clean, quiet, emission-free, and mostly maintenance-free. Additionally, the operational costs are considerably reduced, which might be advantageous financially for drivers who travel frequently. For many years, tiny boats, inflatable boats, and fishermen have all been big fans of electric engines.

A battery typically costs even less than an internal combustion engine, if not the same. The myriad other advantages of the electric motor outweigh the negatives here. We’re interested in hearing from you about your opinions and e-motor experiences as we wait to see how the e-mobility debate plays out in Germany and throughout Europe.
