The weighing systems offered by the Intercomp group, specifically developed for electric vehicles, represent the latest technology for the precise determination of vehicle weight and axle loads. With the rise of electric mobility, the precise measurement of electric vehicles, which have different weight distributions and battery placements compared to traditional vehicles, is crucial for safety, efficiency, and regulatory compliance. These systems are ideal for electric vehicle manufacturers, test centers, maintenance facilities, and fleet managers.
The weight distribution of electric vehicles often differs significantly from their internal combustion engine counterparts, thanks to the high mass and low installation position of the batteries. This weight distribution affects handling, tire wear, and suspension load. Intercomp EV weighing systems are optimized to account for these unique characteristics, providing extremely accurate data.
Electric vehicle weighing systems offer a combination of portability, robustness, and digital accuracy. The system generally includes high-capacity load cells (weighing pads), as well as advanced displays and software for processing and recording measurements.
Although precise specifications depend on the specific model chosen (e.g., portable wheel weigher, low-profile pad), systems intended for electric vehicle applications generally have the following technical parameters:
| Characteristic | Description / Value | Note |
|---|---|---|
| Weighing Capacity (Axle) | Depending on the model, often above 15,000 kg (30,000 lbs) | Of particular importance due to the higher gross weight of electric vehicles. |
| Pontosság | ± 0.1% or better | Ideal for fine-tuning weight distribution. |
| Resolution | 1 kg (2 lbs) or better | The smallest measurable change. |
| Communication | Wireless (RF) or Wired (RS-232/USB) | Wireless options provide flexibility. |
| Display Unit | Digital display, touchscreen options (e.g., TAC30™ type CPU) | Intuitive user interface. |
| Operating Temperature | Wide range (between -20°C and +50°C) | For outdoor and test environment use. |
| Pad Material | High-strength aluminum or steel alloys | Durability and weight optimization. |
| Profile Height | Extremely low profile | Facilitates vehicle roll-on/roll-off. |
The efficiency of electric vehicle weighing systems is greatly enhanced by the associated displays and software. These components enable the immediate interpretation of raw measurement data.
Modern displays, such as the touchscreen CPUs offered by Intercomp (e.g., TAC30™), not only show the weight but are capable of:
Software optimized for EV development (such as solutions based on the principles of ACWeigh™) offer deeper analytical capabilities:
Intercomp weighing systems can be applied across a wide spectrum in the electric vehicle lifecycle:
In the case of electric vehicles, the placement of batteries on the vehicle chassis dramatically affects stability. With the help of weighing systems, manufacturers can check whether the weight of the installed batteries is concentrated precisely in the intended location. Measuring axle load helps confirm that the vehicle's center of gravity is positioned at an optimal height and center for the best handling.
Although primarily measuring vehicle weight, the systems can also be used for charging infrastructure design, especially for high-capacity vehicles loaded with batteries (electric trucks, buses), ensuring that the foundations of charging stations and parking spaces can support the static load.
On test tracks, the scales allow engineers to quickly and repeatedly measure vehicle weight in different configurations (e.g., at various battery charge levels, or with different auxiliary equipment). This is essential for measuring range and performance.
To maintain accuracy, Intercomp systems support regular calibration. Available in the company's portfolio are Force Testing Stands, such as CSM™ or CSA™ systems, enable the calibration of load cells on-site or under laboratory conditions, ensuring that electric vehicle measurement data always complies with the strictest industry standards.
In summary, Intercomp EV weighing systems are indispensable tools for the development and operation of electric vehicles, where precise knowledge of weight and weight distribution is fundamentally important to guarantee performance, safety, and regulatory compliance.
