STMicroelectronics Says Its GDU Boosts Motor-control Flexibility

ZF Premieres Modular eDrive Kit And ZF ProAI At IAA Mobility 2021

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)

      Maruti Suzuki India e Vitara Teased, Launch At Bharat Mobility Global Expo 2025

      Maruti e Vitara

      Maruti Suzuki India (MSIL), the country's largest passenger vehicle manufacturer, has shared the teaser image for its first electric vehicle product - the e Vitara.

      Set to be unveiled at the Bharat Mobility Global Expo 2025, the e Vitara will be made in India for the world. It was recently unveiled by Suzuki Motor Corporation at Milan, Italy.

      Partho Banerjee, Senior Executive Officer, Marketing & Sales, Maruti Suzuki India, said, “The e Vitara is a testament of our unwavering commitment to sustainable mobility and technological innovation. With decades of automotive expertise, we have combined advanced electric technology with a customer-first approach to deliver something truly transformative. At Maruti Suzuki, we have always believed that to promote EV adoption, we need to create a holistic ecosystem that simplifies customers' battery electric vehicle ownership journey.”

      “A critical barrier to the adoption of EVs is the lack of accessible charging. To tackle this issue, we are committed to introduce a reliable and comprehensive EV ecosystem alongside the e Vitara. This will include home charging solutions as well as a nationwide network of fast chargers available at Maruti Suzuki dealerships and service touchpoints. Our goal is to make EVs accessible, convenient, and appealing to a broader set of customers, and this is exactly what we have set out to achieve with the e Vitara,” he added.

        WardWizard Sees 24% Sales Growth In FY2026; New Launches To Drive Retail Performance

        WardWizard

        ​​Vadodara-headquartered electric vehicle company WardWizard Innovations & Mobility recently launched its new range of EV offerings, which it expects to give a new charge to its retail sales.

        It was on 13 December 2024 the Joy e-rik V1 (L5) and Joy Bandhu (L3) electric three-wheelers in the passenger category and Joy Sahayak + Cargo (L5) and Joy Eco Loader (L3) in the electric three-wheeler cargo space were launched by the EV maker, thus marking its entry into the fast-growing electric three-wheeler space.

        The Joy e-rik V1, priced at INR 385,000 (ex-showroom), comes with 10.24 kW li-ion battery, 50 kmph max speed and 140 km claimed range on a full charge. It can be charged in 4.5-5 hours using the 50 Amp charger.

        The Joy Bandhu priced at INR 134,000, uses a 7.2 kW lead-acid battery, has a claimed range of 120 km and top speed limited to 25 kmph.

        On the other hand, the Joy Sahayak + Cargo, priced at INR 424,000, is targeted for payload capacity of 650 kg + driver, max speed of 50 kmph, up to 130 km range on a single charge. It uses a 10.2 kW LFP li-ion battery and can be charged in four hours using 50 Amp charger. The Joy Eco Loader, on the other hand, comes with a payload capacity of 310 kg + driver and is priced at INR 130,000.

        At present, electric three-wheeler sales in India are averaging 56,674 units a month (CY 2024) as compared to 47,204 units last year. What’s also driving the sales is the government incentives like the Centre’s PM E-Drive scheme that provides demand incentives to support purchase of 316,000 e-three-wheelers including e-rickshaws. They are entitled to a subsidy of INR 25,000 in the first year and INR 12,500 in the second year. For the L5 category (cargo e-three-wheelers), the incentive is INR 50,000 per unit in the first year and INR 25,000 the next.

        For the Vadodara-based EV maker, the idea to enter the electric three-wheeler space is on the back of the growing demand for greener last-mile delivery as well as last-mile mobility connectivity options.

        Interestingly, it has already onboarded 27 dealerships that will focus on selling electric three-wheelers. Furthermore, it will also provide preference for its around 900 existing dealer and network partners to sell its new offerings.

        For FY2025, WardWizard Innovations & Mobility estimates to sell around 50,000 units of electric vehicles across electric two-wheelers (low speed and high speed) and three-wheelers (L3 & L5) in India. It estimates that the sales will grow by 22-24 percent YoY in FY2026.

        While it has recently entered the e-three-wheeler space, the company expects the new products to have around 30-35 percent share in its overall sales starting from FY2026.

        On the other hand, reducing its reliance on low-speed electric two-wheeler category, the company also introduced a new high-speed e-scooter ‘Nemo’. Priced at INR 99,000 (ex-showroom), it comes with a 40 Ah NMC li-ion battery and a 1,500W DC brushless hub motor that gives it a max speed of 65 kmph. It has a claimed range of 130 km on a single charge in Eco mode. The e-scooter uses a digital speedometer, 5-inch full-colour TF display and projector LED headlight. The company has targeted a modest 2,000 units sales for Nemo in the next three months.

        The EV maker currently has an installed capacity to produce 73,000 electric two-wheelers, 7,300 L5 electric three-wheelers and 18,250 L3 electric three-wheelers per annum. The company claims that apart from some plastic components and cells being imported, everything has been localised.

        It further aims to start manufacturing its own batteries in the next one year in Vadodara, for which the pilots are underway.
