EV batteries retain over 90%capacity after 160,000 km, study finds
By Areeb Khan
A study battery diagnostics company Aviloo, based on over 500,000 battery health tests across 20 EV models, reveals that most electric cars retain more than 90% of their original battery capacity after 160,000 km. However, battery degradation varies depending on climate, charging habits, battery siz
Aviloo ek Austrian company hai which specializes in battery diagnostics, so apni latest study ke liye, jise "Aviloo Certified EV Battery Report" kaha gaya hai, company ne independently 500,000 se zyada battery health tests conduct kiye hai. Yeh tests 20 specific electric car models par kiye gaye hai, jahan par company ne in EVs ki battery health ko analyze kiya hai. In individual independent tests ki baat karein so these have been conducted between 2022 and 2026 across Europe, North America, South America, Asia and Australia, jiske through we can analyze kar payte hai how electric car batteriesbehave over time and kitna degradation dekhne ko milta hai as the mileage increases.
Battery depreciation in the vehicle was measured after 50,000 kilometers.
This is the average range after 160,000 km Electric car battery ki baat karein, ya phir kisi bhi battery ki for that matter, over the time degradation hona inevitable hai. Battery time ke saath degrade hoti hi hai, and that's the reason future ko lekar ek constant concern bana rehta hai, especially jab humein future mein ek used electric vehicle purchase karne ke baare mein soch rahe hai. However, battery technology ki field mein jo technological advancements dekhe jaa rahe hai, toh yeh concerns abb gradually past ki baat bante jaa rahe hai. Aviloo report ke conclusion ki baat karein so yahan par kaafi reassuring findings saamne aayi hai, especially when it comes to electric vehicle batteries ki ageing. Report ke according, EV batteries actually better age karti hai than what many buyers fear, which means battery degradation ko lekar jo concerns potential EV buyers ke mind mein hote hai, wo reality mein utne significant nahi bhi ho sakte hai. Austrian company ki baat karein so unhone first batteries ke health status ko analyze kiya, jahan State of Health means SoH is undoubtedly the clearest indicator of how a battery ages. Battery ki ageing ko understand karne ke liye they analyzed the SoH at three different mileage intervals. Is analysis mein total 20 electric cars ko include kiya gaya tha, jinki battery health 50,000, 100,000 and 150,000 kilometers par check kiya gaya. Results ki baat karein so, after approximately 1,60,000 kilometers, most of the electric cars tested ne apni original battery capacity ka more than 90 percent retain kiya hai. And agar hum 3,00,000 kilometers ki baat karein, so yahan par bhi most electric cars ne 80 percent se zyada battery capacity maintain ki hai, which shows that EV batteries can retain a significant of their original capacity even after high usage.
Battery degradation in the vehicle was studied after 100,000 kilometers.
The top-performing electric vehicles Is study mein 2 cars clearly stand out karti hai, although inka result different mileage ranges ke according vary karta hai. Inmein se ek Hyundai IONIQ 5 hai, jisne 50,000 or 100,000 kilometres complete karne ke baad best result achieve kiya hai. Iska average respectively 97.13 or 95.27 percent record kiya gaya hai, while 150,000 kilometres ke baad bhi IONIQ 5 ne 93.79 percent ke result ke saath second-best position achieve ki hai. The other one is the Mercedes EQA, so ismein bhi aap notice kar payenge that the three tested cars recorded 96.56, 95.01 and 93.97 percent SoH repectively. Models jaise Hyundai Kona EV, BMW i4 and Audi Q8 e-tron ne bhi good results achieve kiye hai, showing that these EVs are also able to retain a strong level of battery health over time. On the other hand, according to motor.es Nissan LEAF ZE1 and Renault Zoe hai, for a clear reason: inki batteries considerably smaller hai and yeh air-cooled bhi hai, so same distance travel karne ke liye inhe more frequently charge karna padta hai, hence inmein greater wear and tear dekha jaa sakta hai. And what about Tesla? so yahan par results kaafi good rahe hai, but overall rankings mein Tesla models lower-middle part mein place hue hai. For example, Tesla Model Y, jo recent years mein best selling electric car rahi hai, usne an average SoH of 90.32 percent achieve kiya hai. While Tesla Model 3 ki baat karein so iska average SoH 90 percent ke mark se below raha, at 88.04 percent on average.
Battery degradation in the vehicle was studied after 150,000 kilometers.
The Same models, with up to 80% variations. Why? Although battery wear usually grdual hota hai, Aviloo ki study reveal karti hai that sirf mileage hi battery degradation ko explain nahi karta. Despite this kuch equally important factors hai jo battery ki condition ko affect karte hai, including battery size, the climate in which the vehicle is driven, or vehicle ka overall usage. And in sab mein especially charging habits ka bhi kaafi important role hota hai, because battery ko kitni baar or kis tarah charge kiya jaata hai, iska direct impact bhi battery degradation par dekha jaa sakta hai. But study ki baat karein so yahan par ek or important aspect par attention diya gaya hai, and that is the significant variations jo same model ki different units ke between dekhi gayi hai. Two vehicles agar same mileage complete kar chuke hai, tab bhi unki battery health kaafi different ho sakti hai, precisely because of the factors jo humne pehle mention kiye hai. Graphs ko dekhiye and bars ki length par bhi focus kijiye, because yahan par aap notice kar payenge that same model or same brand ki vehicles ke battery health status mein almost 11 percent tak variation dekha jaa sakta hai. Aviloo ki study ki baat karein so ismein several continents ko cover kiya gaya hai, jahan every continent ka apna climate and distinct land use patterns dekha jaa sakta hai. That's the reason different regions ke between kaafi significant differences bhi notice kiye gaye hai, jo many cases mein around 10 percent tak pahunch jaate hai. What this data show is that averages kaafi important information ko mask kar dete hai. While it's true that electric vehicle batteries expected se better perform karti hai over time, but actually ye most relevant finding nahi hai. Isse bhi most important baat ye hai ki battery health different models ke between significantly vary karti hai, or even same model ki different vehicles ke between yeh difference or bhi zyada ho sakta hai. Yeh figures directly real world range, vehicle ki value or reliability mein difference translate karte hai. And without independent testing, aap simply yeh nahi jaan sakte ki aapki vehicle is spectrum mein exactly kahan fall karti hai. News Source: Motor.es Image Source: SWTCH
