Electric vehicles (EVs) are all the rage these days. With their promise of lower emissions and smooth, quiet rides, it’s no wonder that the global demand for EVs has been soaring. However, if you live near the coast — or anywhere prone to flooding — there’s a less-talked-about risk that could make you rethink that shiny new electric car parked in your driveway: saltwater-induced fires from flooded EV batteries.<br /><h2>Saltwater and EV batteries</h2>When it comes to EVs, the heart of the vehicle’s power lies in its battery, usually a lithium-ion (Li-ion) pack. These batteries are highly efficient, but they’re also sensitive to water, especially the salty kind. In September and October 2024, the Southeast U.S. was hit by hurricanes Helene and Milton, which caused catastrophic flooding. Thousands of homes were damaged, and in a particularly frightening twist, 11 electric cars and 48 lithium-ion batteries caught fire after being exposed to salty floodwaters.<br /><br />Saltwater is a conductor of electricity, which means it can get into the EV battery packs, triggering a dangerous reaction. When water seeps into the battery, it can cause a short-circuit between the battery's terminals, which may lead to overheating, violent fires, and even explosions. In many cases, the fire doesn’t start right away — it can take hours or even days after the exposure before a thermal runaway event occurs, causing a dangerous blaze. Once the fire starts, it’s nearly impossible to put out with regular fire-fighting methods. Firefighters often have no choice but to let the battery burn itself out.<br />    <div type="Article" hostid="261" msid="113906136" title="Planning to purchase an EV? Here&amp;#39;s how to ensure it never catches on fire" mstype="2" mssubtype="0"></div>In 2022, during Hurricane Ian in Florida, 36 EVs that had been flooded reportedly caught fire, even some that were being towed on flatbed trucks. The problem lies in how lithium-ion batteries react to saltwater. The metal terminals in these batteries, when exposed to salty water, can corrode and build short-circuiting paths that lead to fires days later. The fire hazard remains even in fully discharged batteries, meaning even seemingly "safe" vehicles after flooding could still pose a serious threat.<br /><h2>The risk to coastal cities</h2>This issue is especially concerning for coastal cities where rising sea levels and hurricanes are becoming more frequent. According to a 2023 report by the International Energy Agency (IEA), <keyword id="381751" type="General" weightage="20" keywordseo="electric-vehicle" source="Orion">electric vehicle</keyword> adoption is growing rapidly in many parts of the world, including India, where EV sales increased by around 50% in the first quarter of 2024 alone. Cities like Mumbai, Chennai, and Kochi are embracing EVs due to their environmental benefits and growing infrastructure support. However, these coastal cities are also at higher risk for flooding, making the combination of increased EV adoption and rising sea levels a perfect storm for potential disaster.<br /><br />In fact, areas prone to heavy rains and floods, like India’s coastal cities, are facing unique challenges. The combination of frequent monsoon floods and rising sea levels presents a scenario where more and more EVs could end up submerged in salty floodwaters, increasing the risk of battery fires in the region.<br /><h2>What does this mean for you?</h2>While electric cars are generally safe under normal conditions, the growing risk of battery fires due to flooding is an important factor to consider if you live in flood-prone areas, especially near the sea. The key takeaway here is that EV owners should take extra precautions when natural disasters loom, particularly hurricanes and floods. Here's what you can do to protect your EV:<br /><br /><ul><li>Move your EV to higher ground: If you're in a flood zone, take your EV to higher ground or evacuate it if possible. This will help prevent it from being submerged in salty water.</li><li>Evacuate early: Be proactive and evacuate before the floodwaters hit. Don't wait for the last minute to move your vehicle to safety.</li><li>After the flood, treat submerged EVs with caution: If your EV has been submerged in water, especially saltwater, it’s essential to avoid using it, charging it, or even moving it until it’s been inspected by professionals. Contact the manufacturer for a thorough inspection of the battery.</li><li>Do not attempt DIY fixes: If your vehicle has been exposed to saltwater, do not try to start it, charge it, or fix the battery yourself. The risks of fire are too high, and professionals are trained to handle such situations safely.</li></ul>

Buying an EV may be a somewhat dangerous move if you live near the sea

<keyword id="19895037" type="General" weightage="20" keywordseo="bengaluru" source="keywords">Bengaluru</keyword> has been suffering from a pretty nasty streak of flooding every time the rains come rolling around, leaving residents struggling with power outages, flooded streets, and impassable roads. With this scenario in mind, let’s dive into how you can protect your vehicle during such conditions and how to care for it afterward. Driving through waterlogged roads can be intimidating, but with the right precautions, you can minimise damage to your vehicle.<br /><h4>1. Assess the <keyword id="23569146" type="General" weightage="20" keywordseo="water-depth" source="keywords">Water Depth</keyword></h4>Before attempting to cross a flooded road, take a moment to gauge how deep the water is. This isn’t just about looking at how far the water reaches on your tires, but also how other cars are handling it. Water deeper than 6 inches (about ankle height) can pose significant risks. For moving water, the danger is even greater. In fact, as little as 4 inches of fast-flowing water can sweep away a vehicle, leading to potentially life-threatening situations. Be cautious — if you're uncertain about the depth, turn around and take a different route.<br /><h4>2. Enter the Water Slowly and Steadily</h4>If there’s no way around the flooded street, approach it slowly. When you enter too fast, your car may aquaplane, which is when the tires lose contact with the road, making it easy to lose control. Aim for a slow and steady speed. as this allows your tires to maintain traction while reducing the chances of creating waves that could send water into the engine. Once in, keep your car moving at a steady pace without stopping.<br /><h4>3. Keep Your Engine Revved Up</h4>One of the major risks when driving through water is <keyword id="22589183" type="General" weightage="20" keywordseo="engine-damage" source="keywords">engine damage</keyword>. If water enters the exhaust pipe, it can cause the engine to seize, potentially leading to a costly repair. To avoid this, keep your engine’s revs high as you navigate through the water. In manual cars, slipping the clutch slightly while staying in a low gear helps maintain higher revs without speeding up too much. For automatic cars, switching to the lowest possible gear before entering the water is a smart move.<br /><div type="Article" hostid="261" msid="114274586" title="Bengaluru rains bring life to a standstill; relief likely after October 18" mstype="2" mssubtype="0"></div><h4>4. Beware of Large Vehicles</h4>If you’re driving near trucks or buses, be mindful of the large waves they create as they plow through floodwaters. These waves can wash over your car, increasing the likelihood of water entering your engine bay or cabin. It’s best to wait for larger vehicles to clear the flooded area before attempting to drive through yourself. Keeping a safe distance ensures you’re not caught in their wake.<br /><h4>5. Know What to Do if You Stall</h4>If your vehicle stalls while driving through water, the immediate response is crucial. Try to restart the car as quickly as possible because the longer the car remains stationary, the greater the chance of water entering critical parts like the exhaust system. However, if the water is too deep or you're unsure, it’s best to avoid restarting to prevent further damage. Instead, push the car to safety if possible, or call for help.<br /><div type="Article" hostid="261" msid="114136105" title="Heavy rains to lash across the country between Oct 12-16, here&amp;#39;s how you can insure your home from rain&amp;#39;s fury" mstype="2" mssubtype="0"></div><h2>Flood-aftercare for your vehicle</h2>Once you've navigated through the floodwaters, your car still requires attention to minimise long-term damage.<br /><h5>1. Dry Your Brakes</h5>Driving through water can leave your brakes wet and less effective, increasing your stopping distance. To dry them out, gently tap the brake pedal once you’re back on dry land. This friction helps evaporate any water that may have settled on the brake discs, allowing them to return to full function. Testing the brakes in a safe spot ensures they’re responsive when needed.<br /><h5>2. Inspect the Air Filter</h5>After driving through a flood, one of the first things to check is the air filter. If water has entered the air intake system, it can damage the engine. A soggy or dirty air filter should be replaced immediately to avoid contaminants entering the engine and causing performance issues later on.<br /><h5>3. Look for Signs of Water in the Engine</h5>If you suspect that water has entered the engine, especially if your vehicle stalled, resist the urge to restart the car. Instead, have the vehicle towed to a mechanic. Starting the engine with water inside can lead to hydrolock, where water in the cylinders causes the engine to seize, potentially requiring a costly engine replacement.<br /><h5>4. Thoroughly Clean the Undercarriage</h5>Floodwater is often filled with debris, dirt, and contaminants that can settle on your car’s undercarriage, leading to rust or corrosion over time. Once the water recedes, give your car a thorough wash, paying special attention to the underside. This will help prevent rust and other issues that could develop due to prolonged exposure to dirty water.<br /><h5>5. Monitor Electrical Components</h5>Flooding can wreak havoc on your car’s electrical systems. After driving through water, test all your vehicle's electronics — lights, indicators, power windows, and infotainment system. Water intrusion can cause malfunctions or short circuits, so if you notice any irregularities, have them inspected by a professional to prevent further issues.<br /><div type="Article" hostid="261" msid="114242444" title="Severe cyclone threat looms large near Chennai as IMD GFS predict landfall by Thursday!" mstype="2" mssubtype="0"></div>By staying cautious during floods and following these post-care steps, you can keep your vehicle in good shape and avoid the worst of water damage.<br />

Rains forcing you to ride through waterlogged areas? Here’s how to safely traverse flooded roads and minimise damage to your vehicles

Over the next week, super heavy showers are set to hit the Indian subcontinent, especially in the states of Tamil Nadu, Kerala, South Interior Karnataka, Konkan and Goa, Madhya Pradesh, Maharashtra, Arunachal Pradesh, and Gujarat, the IMD (<keyword id="19963725" type="General" weightage="20" keywordseo="Indian-Meteorological-Department" source="keywords" meta.keywordsubtype="org" meta.entityname="Indian Meteorological Department" meta.hostid="261" meta.entityid="Indian Meteorological Department">Indian Meteorological Department</keyword>) has predicted. <br /><br /> Yesterday, India's financial capital, Mumbai was hit by a surprise, albeit hefty deluge of rain. Consequently, a yellow alert was issued for Thane, Pune, Palghar and other areas near to Mumbai. <br /><br />Between October 13-16, very heavy rainfalls are also expected in Kerala, Tamil Nadu, Andaman and Nicobar Islands, Gujarat and Andhra Pradesh. It's no secret that incessant rains also bring about significant economic damages. As seen very often in the past, a constant barrage of torrential rains can also quickly create a flood-like situation, which can wipe away houses, vehicles and everything that comes in its way.<br /><br />Per media reports, the average economic impact on India due to <keyword id="19912527" type="General" weightage="20" keywordseo="floods" source="keywords">floods</keyword> between 2011 and 2021 has been a staggering Rs 25,805 crore. <br /><br />Imagine this-your entire se is flooded. Water has seeped into everything—your walls, furniture, and even the plumbing. Without a <keyword id="22058670" type="General" weightage="100" keywordseo="home-insurance" source="keywords">home insurance</keyword>, you'll have to spend a hefty amount towards repairs and to get your life and home back on track. <br /><br /><h2>Getting your home insured</h2>So, if you are wondering how to protect your hard earned material but immovable assets like house, the answer is right in front of you- Home Insurance. <br /><br />Says Dilip Baba, Head of Commercial and Speciality Underwriting, Go Digit General Insurance, "People usually spend their entire life savings on purchasing a home. However, people rarely think about how to protect their investment. By investing in the safety of home insurance, you can enjoy peace of mind knowing that your property is covered in case of unforeseen events.<br /><br />With home insurance, you can opt for three types of coverage-structure, content and comprehensive. <br /><br />While structure simply insures the physical, immovable formation of your house (walls, roofs), content coverage goes a step ahead and takes care of damage caused to your movable items like furniture, electronics and other items due to natural calamities, theft and more, up to a certain limit. This can also include any valuable artwork or antiques, or additional installation like solar panels you might have at your home. <br /><br />A comprehensive home insurance brings together both structure and contents in its insurance ambit. Having a home insurance can not just protect you from natural calamities like floods, but also from unforeseen events like theft, fire and more. The annual premium of a home insurance policy can range between Rs 2,000 to Rs 10,000 depending on the type and extent of coverage taken.<br /><br />Before buying a policy, be sure to clarify whether it offers actual cash value, which considers depreciation, or replacement/reinstatement cost, which covers the full replacement without depreciation deductions.<br /><br />To be on the safe side, you can also choose additional covers like accidental death insurance, or rent coverage, if you lose out on rental income due to damage caused to your property. You can use the carpet area of your house to get a sense of your home insurance requirements. Other covers you can opt for include valuable contents (on agreed value basis under home contents cover), additional living expense cover, tenant liability insurance, among others.<br /><br />Says Amit Bhandari, Chief Technical Officer at Magma HDI General Insurance, "When selecting a policy, it’s crucial to assess the unique risks that your home may face, particularly if you live in an area susceptible to <keyword id="19922196" type="General" weightage="20" keywordseo="natural-disasters" source="keywords">natural disasters</keyword>. You should tailor your coverage to address these risks while considering premium reduction strategies, such as excluding unnecessary coverages".<br />
