The UK\u2019s electric vehicle (EV) market is growing and, although their benefits for everyday motorists are well-documented, these vehicles have lots of untapped potential in harsh industrial environments, such as ATEX.\u00a0Steve Hughes explores the evolving role of EVs in extreme environments<\/strong><\/p>\n\n\n\n

Although electric vehicle (EV) technology is ever-evolving, placing these vehicles in harsh, unforgiving environments might seem counterintuitive. High temperatures can affect the functioning of chargers and reduce the lifetime of vehicles, while environmental conditions, like dust and debris, can have a negative impact on the power electronics of batteries and chargers. However, we are now seeing a shift in mindset and, as designs and components become more sophisticated, it\u2019s reasonable to expect EVs to eventually replace internal combustion engine (ICE) vehicles in hazardous environments, as well as the domestic market.\u00a0<\/p>\n\n\n\n

The importance of cooling<\/strong><\/p>\n\n\n\n

As the domestic EV market has grown, more EVs are being used in harsh and hazardous industrial environments. Recently, there has been a rise in the number of electrified and battery-powered explosion-proof vehicles. Unlike ICE counterparts, these avoid ignition risks in the surrounding atmosphere, reducing the likelihood of explosions. Therefore, there is now a growing gap in the market for explosion-proof trucks and vehicles in ATEX environments like oil and gas processing plants, mining facilities and chemical plants. <\/p>\n\n\n\n

Every electric car battery needs a cooling system, they operate optimally at certain temperatures and are designed to only withstand certain temperature fluctuations. Generally, lithium-ion batteries operate best between 20-40\u02daC, so operating outside this range requires an appropriate cooling system to facilitate heat dissipation. Generally, most electric vehicles use a cooling loop containing an ethylene glycol coolant, which is circulated through the batteries via an electric pump.<\/p>\n\n\n\n

As demand for EVs grows in ATEX and other extreme environments, design engineers and vehicle manufacturers can expand their applications by incorporating liquid cooling systems from the beginning. When relying on air cooling and fans, vehicles are at risk of dust and other debris entering through the vents and causing damage. Every vehicle is designed for a bit of wear and tear, but if EVs are being driven in extreme conditions on a regular basis the lifespan of the car could reduce significantly. <\/p>\n\n\n\n

On the other hand, transferring heat from the engine components using liquids such as water can provide effective heat dissipation without potentially harmful particles entering the system. Meanwhile, an internal thermal switch can be used to execute a safe and controlled shutdown of the system if the coolant runs out or the cooling system fails. <\/p>\n\n\n\n

Braking resistors<\/strong><\/p>\n\n\n\n

As EVs are more widely used in unforgiving environments, another area of importance is braking resistors, which protect the electric motors from voltage rises in the DC link. No resistor is the same, and heavy vehicles and trucks need high-wattage braking power and effective heat dissipation to maintain driver safety when they brake sharply.\u00a0<\/p>\n\n\n\n

Installing water-cooled braking resistors is a vital step before bringing these vehicles into more arduous settings, whether these are processing plants or oil and gas facilities. To help meet this demand, we recently began supplying the BWD 158 standard range<\/a>, <\/strong>which is rated for continuous power of up to 5,000 W. It has a high overload capacity \u2014 up to 33 kW \u2014 and a low surface temperature, which can be lower than the ambient temperature in certain environments. Therefore, this new product lends itself to operation in ATEX environments, where a high possibility of explosion necessitates low surface temperatures.\u00a0<\/p>\n\n\n\n

As EVs overtake traditional ICE vehicles, their role in ATEX and other potentially hazardous environments will only increase. Preparing these vehicles for challenging surroundings like processing plants means starting at the design phase and specifying a liquid cooling system to shield the battery and other electrical components from the effects of extreme heat and debris. Integrating water-cooled braking resistors can also help ensure driver safety is the most difficult of terrains.  <\/p>\n\n\n\n
