Ecovolta: New battery generation for commercial vehicles, machines and boats-generation

The Swiss technology provider Ecovolta is launching a new generation of its evoTractionBattery traction battery. The lithium-ion battery is characterized by a high energy density of up to 172 watt hours per kilogram of battery weight, scalability and extensive safety features.

The battery packs, which are certified according to automotive standards, can be used in a variety of ways and are specially designed for electric commercial vehicles, machines and boats. According to the manufacturer, interest in these applications is currently growing particularly strongly in European and international markets due to increasingly stringent environmental requirements. Municipalities and logistics companies, for example, are increasingly operating electric commercial vehicles in order to meet their climate targets. Construction companies use electric construction machines to meet national emission regulations.

“From construction and agricultural machinery to industrial trucks and cable cars to boats, motorcycles and robots: our batteries are already being used in numerous vehicles and machines. Based on the experience from these applications, our team has developed the new generation of Ecovolta traction batteries,” says Benjamin Friedrich, Ecovolta’s Chief Operating Officer. Among other things, the mechanical construction, materials and connections of the battery have been improved and battery management optimized.

With voltages of 48 volts and 96 volts, four different storage sizes and chaining options, the evoTractionBattery can be used for different applications and installation spaces and up to 400 volts at the overall system level. The integrated battery management system (BMS) is based on the automotive standard ISO 26262. Battery integration is facilitated by standardized interfaces to various on-board chargers. The individual battery packs are also protected against external influences.

“Our customers appreciate the compact design and energy density of our batteries. Customized traction batteries often require extensive system certification. With the interconnection of several Ecovolta batteries to form an overall system, the storage often no longer has to be individualized and recertified. This lowers development costs and time-to-market,” adds Andreas Schimanski, Director Business & Technology of the division.

High security standard and integration support

The evoTractionBattery comes standard with a safety concept that, with the help of cell connections made of electrolytically nickel-plated cold strip, can automatically separate defective cells from the rest of the battery pack in the event of increased current flows. In addition, the BMS monitors all safety requirements for cell monitoring and the battery status in accordance with standards.

Ecovolta supports manufacturers of compact vehicles who are interested in their electrification but do not have the necessary development capacities in the design and integration of complete powertrains. This means that Ecovolta is not just a battery producer, but a provider of complete solutions. The company has already developed complete solutions for transporters, small vehicles and excavators.
