Electric machines vs. diesel: How Do Operating Hours Compare?

When it comes to calculating the working hours of an electric machine, it’s time to throw out the rulebook and start again. Because one of the big benefits of electric machines is that there is no idling time. Unlike diesel machines, if you stop working, the machine stops working too, saving you valuable battery time. 
And idling hours can really add up. From warming up diesel engines so that they are ready to work, waiting while another machine does its part of the job, through to keeping the machine running over break times – it’s not unusual for a machine to be idle 25 to 40% of the time.

In practical terms, this means that if you are used to running a diesel machine for 8 hours a day, an electric machine will only be needed for between 4.8 and 6 hours, taking into account idling of 25 to 40% - that’s a significant difference.

The impact of zero idling time 

Electric machines are designed to provide instant power while you’re working the controls but when you let go, the machine shuts off. This is because they’re fitted with auto electric motor shutdown. How long before the machine shuts down is in the hands of the operator and can be set from three to 20 seconds. Press the controls, and the electric motor turns back on, ready to go again.

No idling time also means less wear and tear on the machine, reducing the need to repair or service parts, which in turn ensures greater uptime and reduced maintenance costs.

So, how can you calculate working hours for electric equipment?

At Volvo CE, we provide estimated ranges for our machines but just like for electric cars, there’s no definitive answer for how long an electric machine will operate on a full charge. It depends on many different factors. Like the type of work you are doing, if the machine is being used constantly or is going on and off, whether the heater or air conditioning is on in the cab, or if the lights are on because it’s dark outside. The outside temperature also has an impact.

Our runtime calculator

Using the hours logged on an equivalent diesel model is not the right way to estimate hours for an electric machine. To help, we’ve developed a Runtime Calculator. It’s simple to use and will help you calculate what a typical working day might look, including machine operating time and if and when you’ll need to charge during the day, so you can plan accordingly.

Can electric machines perform well in cold weather?

That’s right, extreme cold weather can impact how long electric equipment is used in certain applications. There are some top tips to maximise the use of your machine in extreme cold conditions. And if you do operate in colder regions, your local Volvo CE dealer can work with you to ensure you get the productivity and uptime you need from your machine.
