Can an electric delivery truck defy the worst that winter has to offer?
Harbinger, a leading medium-duty electric vehicle (EV) company, has recently demonstrated that it can.
The company has released a video showcasing its EV delivery truck handling icy roads with impressive agility and stability during winter testing in New Zealand.

Innovative design for superior handling
Harbinger’s EV delivery truck features a unique chassis design that places the heavy batteries within the frame, resulting in a much lower center of gravity compared to traditional medium-duty trucks. This innovative layout allows for powerful torque and superior handling, even for vehicles exceeding 13 feet in length. The result is a truck that handles more like a passenger car, even in challenging winter conditions.

YOU WON’T BELIEVE HOW FAR VOLVO’S NEW ELECTRIC SEMI-TRUCK GOES ON A SINGLE CHARGE
Rigorous winter testing
The winter testing program in New Zealand focused on several key aspects:
Braking systems: Harbinger thoroughly tested the truck’s overall braking system, including traction control, stability control, ABS and regenerative braking.

Torque control: Given the substantial torque capabilities of electric vehicles, a primary goal was to demonstrate a driver’s ability to maintain control on ice and snow.

The uphill launch: This tested the ability of the vehicle to climb up to a 25% grade.

Automated hill hold: This feature prevents a vehicle from rolling backward (or forward) when it is stopped on an incline, and Harbinger tested it in low-traction conditions with ice and snow. This feature is common in passenger cars but newly introduced in medium-duty trucks by Harbinger.
Edge cases: About 80% of the tests conducted were designed around 5% of use cases, ensuring the vehicle can handle even the most extreme situations.

Key elements of winter testing
According to John Harris, co-founder and CEO of Harbinger, winter testing is critical for vehicle development, especially for EVs. It ensures that vehicles perform reliably on low-traction surfaces such as ice and snow. The focus is not only on typical cold weather driving conditions but also on less common yet important higher-risk scenarios. This is particularly crucial for EVs due to their significant torque output, which can lead to loss of control if not managed correctly on slippery surfaces. Systems like regenerative braking also need optimization for extreme conditions.

Specific tests for driver safety
Several tests can only be conducted in actual winter weather to stress test for optimal driver safety.
Low-adhesion surface control: Ensuring the vehicle remains maneuverable and stable on snow and ice.
Traction and stability testing: Validating traction control and stability systems under sudden accelerations, braking and cornering.
Regenerative braking on slippery surfaces: Testing how regenerative braking interacts with low-traction conditions to prevent skidding.
These tests help ensure that vehicles can safely handle extreme weather situations, such as when drivers stop steering or accelerating upon hitting a slippery patch of black ice.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

Battery performance in winter conditions
According to Harbinger, all battery-powered vehicles face challenges in cold weather due to two main factors: reduced battery performance and increased energy consumption for cabin heating. At low temperatures, the chemical reactions within the battery slow down, leading to decreased efficiency and power output. Additionally, electric vehicles require energy to heat the cabin, which further reduces driving range. Harbinger addresses these concerns by utilizing a multi-zone heat pump that efficiently provides heating for both the battery and cabin, thereby minimizing the negative effects of cold weather on performance.

Charging in cold temperatures
Charging an electric vehicle in cold weather is generally not problematic. Harbinger’s delivery trucks can be charged without issues, even in low temperatures, ensuring that drivers can maintain operations without interruption. While it’s important to be aware that charging times may be longer if the battery is colder, Harbinger conditions its batteries to the optimal temperature for charging, even when it’s cold outside, to mitigate this inconvenience.
