Ola S1 pro electric scooter catches fire in Pune, company says will take appropriate action, Auto News, ET Auto



This isn’t the primary such occasion of an electrical scooter catching hearth in India. In September final 12 months, two scooters from Pure EV additionally caught hearth adopted by one other from Okinawa in October.
New Delhi: In what could rekindle fears about security in electric vehicles, video of a Ola S1 pro scooter on hearth has emerged from Lohegaon space of Pune on Saturday. Within the 31 second clip, the scooter is seen parked on the roadside of a busy industrial space and is totally engulfed in hearth, presumably affected by a thermal runway. Thermal runaway is an uncontainable exothermic response that may happen inside a lithium-ion battery when it’s broken or short-circuited. As soon as a lithium ion battery is on hearth additionally it is troublesome to extinguish. Instantly upon contact with water it produces hydrogen gasoline and lithium-hydroxide. The hydrogen gasoline is a major impediment because of its excessive flammability.
“We’re conscious of an incident in Pune that occurred with one in all our scooters and are investigating to grasp the basis trigger and can share extra updates within the subsequent few days,” the corporate stated in a press release to ETAuto. “We’re in fixed contact with the client who is completely secure. Car security is of paramount significance at Ola and we’re dedicated to the very best high quality requirements in our merchandise. We take this incident severely and can take applicable motion and share extra within the coming days.”Typically, batteries catch hearth because of poor high quality of lithium ion cells or an inefficient battery administration system. India doesn’t manufacture its personal lithium ion cell–a key part in a lithium ion battery, and corporations supply it from suppliers in South Korea, Taiwan, China and Japan. Ola sources its cells from LG Chem in Korea.There are various kinds of battery chemistries obtainable out there with two distinguished ones for EVs–NMC and LFP. NMC is extra dense in vitality as in comparison with LFP however is taken into account comparatively much less secure. LFP batteries have a considerably larger thermal runaway threshold of 270 levels celsius in opposition to NMC’s 150 levels. Ola makes use of a excessive voltage 56Volt 3.97 kilowatt hour NMC battery. This isn’t the primary such occasion of an electric scooter catching hearth in India. In September final 12 months, two scooters from Pure EV additionally caught hearth adopted by one other from Okinawa in October. In December, one other scooter from Manesar primarily based HCD India caught hearth whereas being charged resulting in the tragic dying of a 60 12 months previous man. But, this is without doubt one of the most excessive profile circumstances given Ola’s stature out there as one of the best funded startup within the trade, which is on the forefront attempting to revolutionize the EV market in India. “That is totally stunning. We had heard stories that Ola was speeding by some protocols in product improvement however we by no means thought they might be negligent in batteries,” stated an trade insider. “This may be very damaging for the trade as an entire. Ola would wish to reply a number of issues.” The Ola electric story in India has been a curler coaster experience in itself and never every part has gone as per plan. To start with, the corporate struggled with ramping up capacities at its mega 10 million unit futurefactory in Tamil Nadu. Consequently, deliveries to clients have been delayed for months. The primary batch of shoppers additionally received the scooter with out a few of the promised options like hill-hold and cruise management features and voice command. In February this 12 months, one buyer Malay Mohapatra additionally suffered from a weird malfunction when his scooter went into reverse mode and accelerated at 102 kph. Because the battery is the guts of any electrical car, its security is without doubt one of the key points that the trade is going through not solely in India however internationally. There was a gradual improve within the variety of hearth incidents commensurate with the rise in gross sales throughout the globe. Final 12 months Common Motors expanded the recall train for its Bolt EVs by 73,000 automobiles to now embrace each Bolt ever manufactured, at a value of practically $ 2 billion. Equally South Korean auto big Hyundai recalled 82,000 EVs after 13 incidents of fireplace have been reported in its compact crossover Kona electrical. This consists of 456 models of the automobile that it offered in India.With a considerably decrease variety of transferring elements, EVs are comparatively easier to provide. The battery nonetheless, is advanced and the car’s total security is determined by the effectivity of the battery administration system–how properly the battery is cooled and the way good the insulation of the pack is from outdoors parts. India doesn’t produce lithium ion cells of its personal which invariably is imported principally from China. Trade sources say that’s the place many of the gray areas exist. Low entry barrier, the promise of excessive development and a prepared made sourcing vacation spot in China–world’s largest electrical car market, has led to scores of corporations mushrooming nearly in a single day. With the standard gamers not totally dedicated to the EV story, the sector is vast open for newer gamers to emerge. Not everyone is a long run participant and the concern is non severe gamers chopping corners to finish up giving the general trade a foul title. Why do batteries catch hearth?You will need to perceive right here why lithium ion batteries catch hearth. At present, Li-ion batteries are throughout us in smartphones and laptops, energy banks and tablets, however the ones utilized in EVs are basically completely different from the remaining. For one, EV batteries retailer as much as thrice extra vitality than laptops or some other family equipment. The abuse they should endure can be vastly completely different and embrace publicity to vast temperature extremes, mud and humidity, vibration because of terrain, water, excessive charges of cost and discharge. To extend a car’s driving vary, it requires excessive voltage, which in flip means lengthy strings of cells and excessive vitality storage. Batteries with flammable electrolytes are notably weak the place automobiles could also be charged in confined storage areas of personal residences and industrial companies. Sometimes batteries include each an oxidizer (cathode) and gasoline (anode in addition to electrolyte) in a sealed container. Combining gasoline and oxidizer is never executed because of the potential of explosion therefore the state of cost (SOC) is a vital variable. Decrease SOCs cut back the potential of the cathode oxidizing and the anode decreasing. Beneath regular operation, the gasoline and oxidizer convert the saved vitality electrochemically (i.e., chemical to electrical vitality conversion with minimal warmth and negligible gasoline manufacturing). Nevertheless, if electrode supplies in some way begin reacting chemically in an electrochemical cell, the gasoline and oxidizer convert the chemical vitality instantly into warmth and gasoline. That is the start of a fireplace hazard scenario. As soon as began, this chemical response will doubtless proceed to completion due to the intimate contact of gasoline and oxidizer, turning into a thermal runaway. As soon as thermal runaway has begun, the power to quench or cease it’s troublesome. As a lot as wherever else, prevention is one of the best treatment right here. What complicates this probably flamable combine is the usage of new electrode supplies to reply the wants of even larger vitality content material and better voltage operation. Electrode supplies characterize a few of the most reactive supplies identified and have a profound affect on the protection and abuse tolerance of the cell and battery pack. The selection of cathode is of specific significance. The fabric of alternative in the present day has lithium alongwith one or a bunch of different supplies like cobalt, nickel, manganese or aluminum. Every has completely different traits relying on the sort and ratio of the metals–Ni(Nickel) has excessive capability, manganese and cobalt have excessive security and aluminum will increase the facility of a battery. The emergence of lithium iron phosphate (LFP) is related. They’re cheaper, don’t use nickel or cobalt and are extra secure and safer. On the flip facet, they’re comparatively much less dense in vitality so producers in search of larger vary and efficiency nonetheless are inclined to go for NMC batteries. Ola does too.Additionally Learn:
Video of Gwalior primarily based Tremendous Eco’s X1 on hearth surfaced on social media just lately. The corporate blamed a Bangalore primarily based third social gathering battery vendor for the mishap. SuperEco additionally provides the scooter to Sahara Evols, the EV agency of Sahara Group that had made a low key entry within the section in mid 2019. With sporadic circumstances of electrical automobiles catching hearth coming to the fore, India wants well timed laws to forestall it. Fortunately in AIS 156 it has probably the most stringent exams worldwide. However there’s a catch–implementation is shoddy. Additionally, since lithium is once more a finite supply, and although it’s recyclable the dependency on just a few nations or a single nation goes to be difficult and I feel the federal government can be attempting to give attention to growing cells in India with the present assets that we’ve got. Therefore, battery know-how will enhance and the density of the battery cells will enhance going ahead. Numerous corporations are engaged on it and it’s a vivid future for EVs.
