STMicroelectronics Says Its GDU Boosts Motor-control Flexibility

STMicroelectronics Says Its GDU Boosts Motor-control Flexibility

STMicroelectronics has announced that its L9908 integrated automotive three-phase gate driver unit (GDU) operates in 12V, 24V, or 48V systems and has flexible input and output channels to fulfil numerous applications in conventional and hybrid/electric vehicles. 

The company said in a statement that the dedicated source connections to the high-side and low-side FETs (field-effect transistors) of each half bridge let users configure the output channels independently to drive various types of loads.  

Besides, six separate PWM (pulse-width modulation) input pins allow independent management of the pre-driver stages for different motor-control strategies, the release pointed out. 

Claiming high accuracy, the company said that there are three differential current monitors for ground-referenced measurements and three channels for real-time phase-voltage monitoring. There is also a rich set of diagnostic and protection features. 

The L9908 simplifies design, saves space, and enhances control of low-voltage fluid pumps, pumps and blowers in ventilation and cooling systems, and electronic seat controls. It can be also used in traction
inverters for mild-hybrid internal combustion engine (ICE) vehicles and 48V full-electric city cars, it said. 

The L9908’s built-in diagnostics allow use in safety-related systems such as autonomous emergency braking (AEB) and advanced electronic power steering (EPS), simplifying certification according to ISO 26262. 

The safety features include SPI-programmable dead-time insertion with shoot-through diagnostic and protection, open-load detection, and short-to-ground and short-to-battery diagnostics. There is also an
SPI-programmable temperature warning and SPI-readable junction-temperature measurement. Other diagnostics include ground-loss detection, over-voltage and under-voltage detection on the power supply pins and FET-driver supply, system-clock monitoring, SPI window watchdog, and a fault-status flag, the release added. 

The flexibility to use the L9908 gate driver in single (12V), dual (24V), and 48V battery applications comes from its wide motor supply-voltage range, from 4.5V to 75V, with the ability to tolerate -14V to 95V on motor-connection pins. The on-chip logic is supplied from an internally generated 3.3V supply and digital I/Os are 3.3V- and 5V-compatible. 

The company said L9908 is AEC-Q100 qualified and available now, in a thermally enhanced TQFP48 package. Pricing starts at USD 3.56 for orders of 1000 pieces. (MT)

Murugappa Group’s TIVOLT Electric Vehicles set to launch e SCV under Montra Electric brand

TIVOLT Electric Vehicles, part of Murugappa Group and a subsidiary of TI Clean Mobility, is gearing up to launch an e-Small Commercial Vehicle (e-SCV). 

Once launched, the vehicle is expected to bring about a significant change in India's mid-mile and last-mile mobility sectors, thanks to its cutting edge technology, distinctive design, strong performance, and durable build quality. The company says the development of the e- SCV will be a culmination of extensive research and rigorous testing.

Founded in February 2022 as a subsidiary of Tube Investments of India (TI), TICMPL is foussing on clean mobility solutions. With the inclusion of e-SCVs as its fourth EV platform, TICMPL is now positioned to offer complete mobility solutions to enterprises and logistics companies, serving their needs across intercity, intracity, and last-mile applications.

Vellayan Subbiah, Executive Vice Chairman, TII said “Montra Electric represents our commitment to enhancing life through eco-friendly mobility solutions, ushering in a new era of growth and innovation for us. The electric vehicle industry is experiencing an exciting phase of development, not only in India but globally as well. We have dedicated our top resources and time to develop this product, and we are looking forward to the customer response upon its launch in the coming months. At Montra Electric, our goal is to offer products and solutions that are beneficial for both our customers and our business, ensuring practicality and sustainability.”

He further stated that India is poised to lead the global adoption of electric vehicles, second only to China. 

“TICMPL is making impressive strides in the electric vehicle sector with a substantial commitment of INR 3,000 crore. Currently, we are developing four platforms, including the successful MHCV truck and electric three-wheeler already in the market. What excites me the most is our upcoming Small Commercial Vehicle (SCV) platform. SCV represents the largest category in the commercial vehicle segment, making our entry into this arena particularly thrilling. This segment is primed to adopt EVs swiftly, supported by policies, government initiatives, and increasing adoption rates. Our dedication to becoming the foremost player in this segment in India is unwavering. The TIVOLT e-SCV is poised to be a standout product, a definite winner in the market,” concluded Vellayan Subbiah.

Mahindra Last Mile Mobility Sets Up Three-Wheeler EV Charging Stations In Mumbai Suburbs

Mahindra Last Mile Mobility Sets Up Three-Wheeler EV Charging Stations In Mumbai Suburbs

Mahindra Last Mile Mobility (LMM), a division of the Mahindra & Mahindra Group, has set up several charging stations near autorickshaw stands, auto driver home clusters and junctions. LMM has done this through strategic charging vendors. The division has done so to boost EV penetration in Mumbai and its suburbs.

Chargers have also been installed at Mahindra outlets and Mahindra Mitra Technician spots wherein customers can charge their three-wheelers. The charging points have been positioned in strategic locations like Malad, Kandivali, Mira Road, Navi Mumbai, Vasai, Virar, Andheri and so on. This is an ongoing process and the Mahindra team, along with key stakeholders, has identified additional charging spots in and around Mumbai and with due approvals, will commence work. The auto driver partners, too, have been notified of these additional charging points.

In addition to this, more than 60 mechanics have been trained by LMM’s service personnel to handle Mahindra three-wheeler EVs.

Electric Fast Charging Station At Mumbai’s CSMIA

Electric Fast Charging Station At Mumbai’s CSMIA

Six robust DC fast EV charging stations have been installed at Terminal 1 and Terminal 2 of Mumbai’s Chhatrapati Shivaji Maharaj International Airport (CSMIA). They are available for service as Public Charging Stations (PCS) for passengers as well as guests visiting the airport. 

The EV station at Terminal 1 is at P1 - Multi-level Car Parking (MLCP). At Terminal 2, it is at P5 – MLCP. There is another station at the Airside of Terminal 2 as well. The owners of private EVs and commuters who will avail of the charging stations at MLCP in either terminals will be billed only for the charging sessions. They will be given a deduction against the parking fees.  

Adhering to all the requirements, policies and protocols outlined by the regulators, the charging stations at either terminal of CSMIA are of the CCS Type II Dual Gun 60 kW and GB/T (DC 001) Dual Gun 40 kW Charger type and compatible with all the prevailing EV cars in the country. There would be augmentation of 60 kW and 240 kW capacity EV chargers to cater to the needs of Airside logistics.  

CSMIA runs on 100 percent renewable energy with its onsite solar power plant, Vertical Axis Wind Turbine (VAWT) and procures green power. For EV charging, the airport will source 100 percent green power, according to sources in the know of the development.
