L&T Tech’s e-VOLTTS platform to accelerate EV development

Bangalore-based L&T Technology Services, a leading pure-play engineering services company, has launched its e-VOLTTS platform. The company says the platform is designed for next-generation electric vehicles along with an EV Lab and in-house autonomous drive platform.

The in-house-developed e-VOLTTS is a scalable and modular high-efficiency reference platform that can be easily customised for use in a wide range of vehicle segments such as off-highway vehicle, passenger cars, two- and three-wheelers.

It will also serve as a reference design and is reusable as well as customisable, thereby enabling faster EV related product development. L&T Tech says this will effectively further consolidate its position as a one-stop shop for e-mobility solutions with expertise ranging from build to specification definition to vehicle level integration. 

The e-VOLTTS platform is designed to offer distinct features in tune with the expectations of the evolved needs of EV buyers. These include an electric propulsion system comprising an inverter converter topology that enables a compact, cost-attractive electric drive proposition. Furthermore, the ‘heart’ of the car, has a traction motor that is equipped with excellent torque characteristic thereby ensuring that with a single charge the vehicle runs an optimum distance.  

For the battery, it is designed to reduce excess heat to the environment utilising various factors such as cell selection, cell spacing, pack construction, thermal materials and battery enclosure design.  

The prototype version of the EV developed by LTTS also comprises a 5G-enabled next-gen digital cockpit with multiple displays. The company says these capabilities have grabbed interest from global customers and helped win multi-year engagements with e-powertrain manufacturers.

New autonomous drive platform launched
L&T Tech has also launched an in-house-developed autonomous drive platform which integrates various ADAS applications and mechatronics (precise control for mechanical components).

The platform is showcased in LTTS’ prototype autonomous vehicle which comprises LiDAR cameras and over a dozen ultrasonic sensors which can make decisions through a central control unit. Its home-grown scalable sensor fusion framework supporting 3D LiDAR system and other advanced sensor applications provide superior driver safety helping its customers come closer to the ultimate goal of autonomous cars. 

The pure-play engineering company has also set up what it says is a one-of-its-kind EV Testing Lab at its Bangalore delivery centre that will cater to EV component level testing. The lab provides various types of electric powertrain testing such as performance testing, endurance testing, and functional testing of e-motors, inverters, DC-DC converters, battery, and on-board / off-board chargers.
