EV range in Winters: As winter tightens its grip, electric vehicle (EV) owners witness a curious phenomenon – plummeting range. While internal combustion engine (ICE) cars flourish in the cold, EVs face an unexpected foe: climate control. This article delves into the chilling truth of how your comfort settings can drain your battery.
Case in Point:
A Team-BHP user shares their experience with a TATA Nexon EV LR. Previously boasting a comfortable 280-300 km range, the winter chill has shrunk it to a meager 230-250 km. Highway journeys, once spanning 240-250 km, now fall short at 200 km. What culprit lurks behind this dramatic drop? The ever-faithful heater.
Electric Heat: A Battery-Hungry Beast:
Unlike ICE cars where engine heat warms the cabin, EVs rely on electric resistance heating, a notorious battery guzzler. This user, accustomed to a cozy 23-24 degree climate setting, witnesses the harsh reality – their heater now consumes a staggering 23% of the battery’s juice! One-fourth of their precious range vanishes solely for warmth.
The Double Whammy: Defogging Dilemma:
Adding to the woes, the climate control system often runs the AC compressor simultaneously to combat windscreen fogging, further draining the battery. This user’s brave experiment of ditching climate control altogether reveals a stark truth – a 120-125 Wh/km consumption, a significant improvement over the heater-dependent 150-155 Wh/km.
Beyond Delhi’s Chills, a Global Concern:
The winter range dilemma isn’t just a Delhi phenomenon. European EV owners have long lamented similar struggles. This highlights the critical need for awareness among both current and prospective EV buyers, especially regarding long-range vs. medium-range decisions during colder months.
Heat Pumps: A Ray of Hope?
The user emphatically calls for manufacturers to consider adopting heat pump technology in Indian EVs. Heat pumps, known for their energy efficiency, could be a game-changer, especially in northern India where a large chunk of EV sales occur.
The Takeaway:
Winter throws a curveball at EV owners. Careful climate control management becomes crucial to maximize range. This case study serves as a cautionary tale, highlighting the significant impact of heating on EV range and the potential of heat pump technology as a solution. As winter beckons, remember, cozy comfort comes at a battery cost in your EV. Choose wisely and stay charged up!
