Batteries and thermal solutions from Webasto for the construction sites of the future

E-mobility plays a key role in reducing greenhouse gas emissions locally, not only in private transportation but also on construction sites. The advantages are manifold: electric construction machines work extremely efficiently, reliably and quietly. With its robust and scalable standard battery systems, Webasto is already powering a range of special and construction vehicles from well-known manufacturers.

 

At the same time, Webasto's electric thermal management solutions ensure optimum performance of the traction batteries and comfortable temperatures in the driver's cab - a "winning team" for your electrification projects.

Powerful performance for power-hungry electric vehicles

The Standard Battery Pro 40 is the first choice for electric construction machinery and special vehicles. Up to 18 standard batteries, each with an energy content of 40 kilowatt hours, can be combined to supply even the most power-hungry construction machines with enough energy for an entire working day. A robust aluminum housing protects the high-voltage battery and meets the highest requirements for safety, availability and stability, even in demanding working environments. With dimensions of 960 x 687 x 302 millimeters and a weight of 297 kilograms, it can be installed both vertically and horizontally, giving system integrators and vehicle manufacturers maximum freedom during installation.

The Standard Battery Pro 40 meets all the necessary standards for construction and special vehicles, including the ECE R100 and R10 approvals as well as the CE specifications for mobile machinery. It also covers a range of safety standards, including ISO 6469, ISO 19014 and ISO 26262 (ASIL level C). The high-voltage battery is protected against the ingress of dust and water on the construction site in accordance with IP67.

 

Our quality promise: Webasto develops and produces both the control electronics and the battery at its German sites in Schaidt, Schierling and Stockdorf.

Electrical thermal management for man and machine

The heart of electric vehicles is the traction battery. It stores the energy that powers your construction machine throughout the working day. With the electrical Battery Thermal Management (eBTM), Webasto offers a compact and scalable plug-and-play thermal management solution that ensures the optimum performance of traction batteries in electric construction vehicles and machines.

 

In combination with the eBTM, the batteries deliver their maximum performance during operation regardless of the outside temperature and load, achieve the longest possible life cycle and can be charged more quickly. Webasto's electrical Cabin Thermal Management (eCTM) goes one step further.

The eCTM combines electrical thermal management for the traction batteries with electrical air conditioning solutions for the driver's cab in a modular system. The eBTM allows continuous monitoring of the operating temperature of the traction batteries in your construction vehicle and ensures a balance between the heating and cooling circuits. In this way, the eBTM keeps the temperature of the installed 400 or 800 volt traction batteries within the ideal range of around 22 degrees Celsius at all times. Depending on the vehicle type, application and number of batteries installed, several units can be combined. The plug-and-play thermal management solution dynamically adjusts the temperatures during different load phases. It can also condition the batteries during the charging process, thus reducing the charging time.

Key facts

  • Thermal management for traction batteries
  • Scalable plug-and-play solution
  • Maximum performance of traction batteries regardless of the outside temperature
  • 8 kilowatts of cooling or 10 kilowatts of heating power
  • For battery systems with a total capacity of up to 210 kilowatt hours
  • Suitable for standard Webasto batteries and third-party battery solutions
