Euler Motors presents EVs with advanced thermal management  

By Staff Report December 23, 2024 6:56 pm IST

Euler Motors is a major part of India’s EV landscape, which includes advanced liquid cooling, robust BTMS, predictive maintenance, and connected systems. Their reliable, long-lasting batteries are to ensure optimal performance in extreme conditions and promote sustainable mobility.

What advanced technologies does Euler Motors deploy to produce reliable battery systems?

Euler Motors was the first to introduce cutting-edge liquid cooling technology, for long-lasting battery life, setting a new standard in the Indian commercial EV market. This innovative system prevents lithium plating during charge and discharge processes, which can degrade the cell’s charge-holding capacity over time. This effect becomes more severe at higher temperatures, and by keeping the battery cool, our liquid cooling system mitigates this issue, resulting in longer battery life and better performance.

With the launch of our first four-wheeler, the Storm EV, we continue to push the boundaries of performance with our ArcReactor™ 200 technology. It provides optimal battery performance while extending battery life even in extreme weather conditions. It is supported by a Vapour Compression Engine that provides dedicated thermal management, maintaining ideal battery temperatures for maximum efficiency.

The Storm LongRange 200 EV’s 30kWh battery features a proprietary laser-welded design, ensuring reliability in extreme conditions, from Rajasthan’s heat to Kashmir’s cold. It is fully water- and dust-resistant (IP67 rating) and utilises vapour compression for efficient cooling, extending battery life even in temperatures ranging from -40°C to 70°C. Proactive measures have also been implemented to address the depth of discharge concerns by incorporating higher reserves (10-15%). Predictive maintenance capabilities enhance reliability by monitoring the battery’s discharge levels and preventing overuse. We are redefining reliability and performance and ensuring our customers can trust Storm EVs for years.

How do the liquid-cooled battery pack and BTMS contribute to the overall performance of your vehicles?

Our vehicles are meant to carry maximum payload, which results in higher currents. Our battery pack incorporates active liquid cooling during charge and discharge cycles, even in extreme conditions. This improves performance, extends battery life, and reduces total cost of ownership. Integrated sensors continuously monitor the battery’s temperature, activating a coolant circulation mechanism when temperatures exceed predefined thresholds. We ensure the longevity and performance of our battery systems this way.

The Battery Thermal Management System (BTMS) in the HiLoad EV and Storm EV provides efficiency even under heavy loads or high temperatures. With real-time temperature regulation and the ability to optimise performance through software updates, the 4th generation BTMS enhances vehicle longevity while reducing the need for hardware upgrades. It reduces the cost while keeping the performance consistent.

How has Euler Motors contributed to reducing the environmental impact of commercial vehicles in India?

Our core vision is for India’s transition to sustainable mobility. The HiLoad EV has already helped reduce over 15,000 tonnes of carbon emissions, equivalent to the positive impact of planting 5.2 lakh trees. With the Storm EV, we aim to expand this impact and offer a zero-emission alternative for intra- and intercity cargo transport.

For example, the Storm LongRange 200 EV provides a 200 km range, enabling intercity movement between nearby locations, typically serviced by diesel vehicles. By offering this practical alternative, we help reduce emissions and improve air quality in urban and semi-urban areas. The focus is making EV adoption a seamless transition for businesses, ultimately contributing to cleaner environments.

How have you addressed battery life, charging infrastructure, and vehicle performance in diverse Indian conditions?

Battery health is impacted by both temperature and daily depth of discharge. We maintain optimal performance, even during extreme and temperate mid-seasons when humidity increases. The BMS monitors battery health and temperature, alerting the Vehicle Control Unit (VCU) if thresholds are exceeded. The VCU recalibrates energy usage and oversees power flow, enhancing efficiency and user experience, especially in high heat.

We have enhanced our charging infrastructure through strategic partnerships supporting the electrification of logistics and commercial transport in India. We partnered with Fyn Mobility to develop charging infrastructure across the country. The Storm LongRange 200 EV supports CCS fast charging, delivering a 100 km range in just 15 minutes, while the Storm T1250 EV offers similar fast-charging capabilities for shorter trips. This helps to alleviate concerns around downtime, making businesses operate efficiently without disruptions.

How do Euler Motors’ connected systems and predictive maintenance features benefit your customers?

Our connected systems, available through the Shepherd platform, provide real-time insights into vehicle performance, including fleet tracking, battery health, and charging status. This allows fleet managers to make informed decisions that optimise operations and reduce downtime.

Predictive maintenance features ensure that potential issues are addressed before they escalate into problems, further enhancing vehicle uptime. Additionally, our Over-The-Air (OTA) updates continuously refine vehicle performance based on real-world data and customer feedback. Security is also a priority, with features like 24/7 CCTV monitoring and anti-theft immobilisation providing added layers of safety for both the vehicle and its cargo.

We aim to provide customers with the tools they need to manage their fleets more effectively, reducing costs and improving operational efficiency by integrating these connected systems.

What steps are you taking to extend battery warranties and develop long-lasting technology?

Long-term reliability is a key focus for us. We offer a standard battery performance warranty of 3 years or 80,000 kilometres. For the HiLoad EV, we guarantee a 10-year battery lifespan, with a battery module replacement in the 5th year to align with EMI periods.

We provide an extended warranty of 7 years or 2,00,000 km for the Storm EV, backed by rigorous testing protocols, including submersion and stress tests across different climates. Our modular battery design allows cell replacements after five years, extending battery life without replacing the entire unit. This process retains essential components like electronics, sensors, temperature controls, and the battery management system, reducing ownership costs and encouraging EV adoption.
