Electric truck chassis

Types of Electric Truck Chassis

The Electric Truck Chassis is an essential component of electric commercial trucks. It provides the structure and support for mounting various truck components. The chassis design has a significant impact on truck performance, ride quality, and handling. Here are some common types of electric truck chassis:

• BEV Chassis

  The Battery Electric Vehicle (BEV) chassis is a standard chassis for most electric trucks. It uses batteries as the only power source. The batteries provide all the energy needed to power the truck's electric motors. No other alternative energy sources or power generation systems are included with the BEV chassis.

• FCEV Chassis

  The Fuel Cell Electric Vehicle (FCEV) chassis uses hydrogen fuel cells to power the electric motors. The fuel cells convert hydrogen into electricity, which directly powers the motors. Because the reaction in the fuel cells only produces water as a byproduct, FCEV trucks have zero emissions, just like BEV trucks. However, FCEV trucks can refuel with hydrogen in just a few minutes, similar to gasoline vehicles. This quick refueling capability is a major advantage of FCEV technology over BEV technology.

• Hybrid Electric Vehicle (HEV) Chassis

  The Hybrid Electric Vehicle (HEV) chassis combines an internal combustion engine (ICE) with an electric motor and batteries. The ICE generates electricity to charge the batteries while driving. The electric motor can also assist the ICE in driving, providing extra torque for acceleration. This combination allows HEV trucks to use their batteries and electric motors efficiently, improving overall energy efficiency compared to traditional ICE-only trucks. Regenerative braking is another feature of HEV trucks. When braking, the electric motor acts as a generator, converting kinetic energy into electrical energy to recharge the batteries. This captures energy that would otherwise be lost in traditional braking systems.

Specifications and maintenance of electric truck chassis

Electric truck chassis specifications vary according to use cases. Here is a general guide:

• Gross Vehicle Weight Rating (GVWR)

  GVWR is set by the manufacturer and determined by the electric truck's chassis construction. The rating shows the maximum weight for safe operation, including the vehicle's weight and cargo. Electric trucks with a higher GVWR can transport heavy loads and have a more robust chassis.

• Wheelbase

  The wheelbase is the distance between the front and rear axles. Longer electric truck chassis have a longer wheelbase, which improves stability and offers a larger cargo space. Shorter wheelbases make the trucks more maneuverable.

• Chassis Length and Width

  The size of the electric truck chassis affects aerodynamics, handling, and the cargo area. A large truck has a wider and longer chassis, while a compact truck has a small chassis.

• Payload Capacity

  Trucks with higher electric payload capacities have robust chassis and suspension systems. The electric truck's payload capacity is limited by its GVWR and can affect driving performance and safety if exceeded.

• Towing Capacity

  Electric truck towing capacity is an important specification for truck owners. The electric truck's towing capacity depends on the electric truck chassis size, weight distribution, and towing equipment.

• Axle Ratio

  Electric truck chassis have different axle ratios suitable for various applications. A higher axle ratio gives more torque for hauling and climbing, while a lower ratio gives better fuel efficiency.

• Suspension

  Electric trucks have different suspension systems, such as leaf springs, coil springs, and air suspension. The suspension system is based on the truck's design and intended use. Electric trucks with air suspension have a more comfortable ride.

• Brakes

  Electric trucks use regenerative braking systems, which increase the truck's battery life. The truck's brake systems vary according to the truck size and its GVWR.

• Motor Power and Torque

  The power and torque of the electric truck motor determine the truck's acceleration and top speed. The truck motor power is measured in kilowatts (kW), while the torque is measured in newton-meters (Nm).

• Battery Capacity

  The battery capacity of electric trucks is measured in kilowatt-hours (kWh). High-capacity trucks can cover longer distances and support more load than trucks with lower battery capacity.

• Length and Height

  Electric trucks differ in dimensions. Some have a compact size for urban areas, while others have a large truck body for highway and long-distance travel.

• Drive System

  Electric trucks can have rear-wheel drive, front-wheel drive, or all-wheel drive. The drive system is determined by the electric truck's design and purpose.

• Wheel Size

  The electric truck's wheel size affects handling, ride quality, and fuel efficiency. Electric trucks have different wheel sizes suited for various driving conditions and applications.

• Aftermarket truck chassis maintenance

  Proper maintenance of electric truck chassis parts enhances truck performance and durability. Truck owners should schedule regular maintenance checks with professional mechanics. The truck's user manual has a maintenance schedule with recommended service intervals.

• Keep the electric truck chassis clean by washing it regularly. Inspect the truck chassis for damage or worn-out parts. Truck owners should promptly repair or replace damaged electric truck chassis parts. Only use genuine replacement parts when repairing the truck.

How to choose electric truck chassis

When buying an electric truck for business, it is important to know the chassis to meet the business requirements. Here are some factors to consider when selecting a suitable chassis for business needs:

• Business requirements: Consider the business requirements before selecting a truck chassis. For example, a business that does long-distance delivery may need a truck with a chassis that offers long-range capacity.
