What\u2019s less discussed, however, are the off-road applications that can also benefit from electrification. That includes agricultural equipment. Simone Bruckner explains how the agricultural sector can electrify, and technologies that can help.<\/strong><\/p>\n\n\n\n<p>According to the UK Government\u2019s Department for Environment, Food, &amp; Rural Affairs\u2019 <a href=\"https:\/\/www.gov.uk\/government\/statistics\/agri-climate-report-2021\/agri-climate-report-2021#:~:text=In%25202019%252C%2520when%2520compared%2520to,47%2525%2520of%2520total%2520methane%2520emissions\">Agri-climate report 2021<\/a>, in 2019, agriculture was the source of 10% of total greenhouse gas emissions in the UK. The sector was also responsible for 68% of total nitrous oxide emissions, 47% of total methane emissions and 1.7% of total carbon dioxide emissions.<\/p>\n\n\n\n<p>However, despite these figures, it seems the farming community is seeking change. The 2021 <a href=\"https:\/\/www.gov.uk\/government\/statistics\/farm-practices-survey-february-2021-greenhouse-gas-mitigation-practices\">Farm Practices Survey<\/a> indicated that 67% of farmers consider recognising greenhouse gases to be either fairly or very important when taking decisions about their land, crops and livestock. One method of reducing emissions is to electrify equipment that traditionally runs on fossil fuels, such as tractors.&nbsp;<\/p>\n\n\n\n<p><strong>A necessary change<\/strong><\/p>\n\n\n\n<p>Modern agriculture depends on a fleet of heavy-duty vehicles, from pickup trucks and small utility vehicles to massive tractors and combines that can weigh several tonnes, plus attachments. This machinery is commonly powered by diesel engines, mostly due to their higher torque and dependability. And here is where an electrification challenge may lie.<\/p>\n\n\n\n<p>The electric sceptics of the agricultural industry claim that the largest problem with electrifying tractors and other heavy vehicles is that battery-powered options don\u2019t have the energy density of a diesel model required to do long, hard work in the field. As load impacts on battery life, pulling a piece of heavy equipment would drain power fast. Using diesel, therefore, means a farmer will not have to worry about filling the tank for 10 to 12 hours while out on the job.<\/p>\n\n\n\n<p>Battery technology, therefore, needs to be developed in order to withstand the heavy loads of agricultural vehicles and supply a lasting and reliable source of power. Some manufacturers have produced compact, swappable batteries to extend the length of operation. Another option, developed by John Deer in 2019, features a long power cable that\u2019s only available for farmers who are able to produce their own electricity via the use of solar panels, manure digesters or windmills.<\/p>\n\n\n\n<p>Right now, despite its challenges, attempts to electrify farming vehicles are well underway. The work is being done, and given the mounting pressure to decarbonise all areas of industry, it won\u2019t be too long before electrification becomes more accessible to the masses. In addition to the battery itself, manufacturers must consider the other components that make electrifying possible. &nbsp;<\/p>\n\n\n\n<p><strong>Dynamic braking<\/strong><\/p>\n\n\n\n<p>Resistors will play a role in electrification, to support the process of regenerative braking. As part of regenerative braking, excess kinetic energy is used to recharge an EV\u2019s battery. It is able to do this because the electric motor in an EV can run in two directions: one, using the electrical energy, to drive the wheels and move the vehicle, and the other, using the excess kinetic energy, to recharge the battery.&nbsp;<\/p>\n\n\n\n<p>When the driver lifts their foot off the accelerator pedal and steps on the brake, the motor starts to resist the vehicle\u2019s motion, \u2018swapping direction\u2019, and begins putting energy back into the battery. As a result, regenerative braking uses the EV\u2019s motor as a generator to convert lost kinetic energy into stored energy in the battery.&nbsp;<\/p>\n\n\n\n<p>Regenerative braking can support the ongoing dilemma of electric tractor battery range. However, to work effectively, other technologies are needed to make the process safe and effective. If the vehicle\u2019s battery is already full or there is a failure, regenerative braking cannot happen as the excess energy has nowhere to go and must be dispelled safely. If not dissipated, it won\u2019t be possible to slow down the vehicle, resulting in braking failure. To make electrifying agriculture safe, resistors are used to collect excess energy and dissipate it safely.&nbsp;<\/p>\n\n\n\n<p>Cressall\u2019s<strong> <a href=\"https:\/\/bit.ly\/3xaq1hw\" target=\"_blank\" rel=\"noreferrer noopener\">EV2 dynamic braking resistor<\/a><\/strong> converts excess kinetic energy during the braking process into heat that can be dissipated or used in other parts of the vehicle, like to heat the tractor\u2019s cabin. It is a high-power density, lightweight and compact resistor that has proven to meet all major shock and vibration standards, suitable for all automotive applications, not just on-road vehicles.<\/p>\n\n\n\n<p>While electrifying on-road vehicles has become well recognised, the same attention must be paid to other areas of the automotive industry. The agricultural sector is beginning to wake up to the prospects of decarbonising, and positive steps are being taken towards electrification. To make it happen, agricultural vehicle manufacturers need to consider the technology that can make agricultural EVs more efficient, and safer.&nbsp;<\/p>\n\n\n\n<p>Simone Bruckner is managing director of resistor manufacturer <strong><a href=\"https:\/\/www.cressall.com\/ev-advanced-water-cooled-resistors\/\" target=\"_blank\" rel=\"noreferrer noopener\">Cressall<\/a><\/strong>. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>The electrification of the on-road transportation sector is well documented.
