Mercedes-Benz do Brasil has presented the fully electric eO500U bus chassis. The bus chassis was specially designed for Latin American cities and will be produced in São Bernardo do Campo, in the Brazilian state of São Paulo, from 2022 on.


The fully electric bus chassis has a range of up to 250 kilometers. The battery charging system of the eO500U is a plug-in system with the same technological standard that Daimler Buses has installed in the fully electric Mercedes-Benz eCitaro city bus. A full charge of the high-voltage batteries takes around three hours.

The fully electric eO500U bus chassis is part of our global development strategy for electromobility. Our goal is to make local public transport even more environmentally friendly and to improve the quality of life in cities.

—Gustav Tuschen, Head of Product Engineering and Purchasing Daimler Buses

The fully electric eO500U bus chassis will be launched in Brazil and in other selected Latin American countries. If there is a corresponding customer interest, use outside of Latin America is also conceivable.

The eO500U is a model from the O-500 series, which is also the basis for the Mercedes-Benz Super Padron city bus. The low-floor vehicle can accommodate city bus bodies with a length of up to 13.2 meters and offers space for up to 86 passengers. It is driven by wheel hub motors on the rear axle.

Taking into account the experience with the Mercedes-Benz eCitaro, the chassis was completely developed in Brazil and put through intensive tests by engineers from Daimler Buses in Germany and Brazil.

Mercedes-Benz do Brasil is the largest bus and truck manufacturer in Latin America. The bus plant in São Bernardo do Campo was opened in 1956 and specializes in the development and production of bus chassis.

Toshiba, Sojitz and CBMM partner to commercialize next-generation Li-ion batteries with NTO anodes

Toshiba Corporation, Sojitz Corporation, and CBMM have entered into a joint development agreement for the commercialization of next generation lithium-ion batteries using niobium titanium oxide (NTO) as the anode material.

One of the major requirements for rechargeable battery development is greater energy density and faster charging. NTO has twice the theoretical volume density of the graphite-based anode generally used in lithium-ion batteries. In June 2018, the three companies entered into a joint agreement to develop NTO’s potential as an anode material.

This work, led by Toshiba’s Corporate Research & Development Center, has reached fruition with the development of prototype cells, and the companies have now agreed to extend collaboration for accelerating development of mass production processes and the early commercialization of next-generation lithium-ion batteries.


Prototype cell & Niobium Titanium Oxide (NTO)


The three companies aim to commercialize high energy density, quick charging batteries in FY2023, mainly targeting application in commercial e-vehicles. CBMM has contracted with Volkswagen Caminhões e Ônibus, a pioneer in the development and serial production of electric trucks in Latin America, to mature this technology further in real application. Toshiba and Sojitz will support this project.

The NTO battery will be installed on new electric vehicle designed by Volkswagen Caminhões e Ônibus as a pilot project and parties will collect the valuable vehicle operation data.

Niobium (Nb), one of the metallic elements, is an important additive in the production of high-grade steel alloys, including high-tensile and stainless steel, and its ability to enhance strength while reducing weight has made it indispensable for automotive applications. Brazil-based CBMM is the world’s leading producer of niobium and is well-known for its strong technology and product development programs.

As CBMM’s shareholder and distribution agent in the Japanese market, Sojitz has cultivated the knowledge and capabilities needed to establish a stable supply system and assist in the development of different applications for niobium.

Towards commercialization, Toshiba aims to secure stable supply of niobium materials from CBMM and Sojitz, and the three companies will target to gain market share in the rapidly expanding secondary battery market by utilizing CBMM and Sojitz’s global network.

SAKOR Technologies provided the University of Houston’s Department of Electrical and Computer Engineering with a dynamometer test system designed to test motor and inverter designs for use in hybrid and electric vehicle applications.


The system features dual opposin 7.5 kW AccuDyne four-quadrant AC motoring dynamometers, variable frequency drives, and a variety of subsystems configured for testing electrical machines. The dynamometers are capable of bi-directional loading and motoring, allowing researchers to test different algorithms and designs. One dynamometer will be used for testing permanent magnet motors and the other will be used to test induction motors.

The dynamometers feature regenerative operation, which recovers most of the load energy and makes the system extremely power efficient. They operate at up to 8,000 revolutions per minute (rpm) and offer up to 150% overload capacity, making them compatible with most small hybrid and electric vehicle architectures.

117A340B-2DB3-4E29-97FD-7CFE49ED48C3

The system is automated by SAKOR’s DynoLAB test automation control system which provides the capabilities necessary for the typical test engineer and/or technician to design and implement complex test procedures without the need to learn a programming language. tevp

We are extremely happy to be involved with universities pursuing important research and development necessary to design new energy efficient technologies. This flexible testing system is ideal for use in an academic environment and users can develop and test many different algorithms and technologies with a single test system.

The Ford Pro all-electric police pilot vehicle based on the 2021 Mustang Mach-E SUV has become the first all-electric vehicle to pass the rigorous Michigan State Police 2022 model year evaluation. (Earlier post.)


Testing included acceleration, top speed, braking and high-speed pursuit, as well as emergency response handling characteristics. Michigan State Police is one of two law enforcement agencies that annually test new model year police vehicles and publish the results for use by agencies nationwide.

The fact that the Mustang Mach-E successfully stood up to the grueling Michigan State Police evaluation demonstrates that Ford can build electric vehicles that are capable, tough and reliable enough for even the most challenging jobs. We understand the needs of our commercial customers and are committed to unlocking new electrification opportunities for them.

—Ted Cannis, CEO of Ford Pro

Ford Pro submitted the all-electric police pilot vehicle for testing in the Michigan State Police 2022 model year evaluation 18-20 September. Michigan State Police will publish results for vehicles tested on its website later in the fall.
