When EV Power Distribution Units proliferate, manufacturers and end users may keep all essential switching components in one place. A power distribution unit is an enclosure with many components combining different voltages, amperages, and functions connected via internal busbars, cable harnesses, and accessed externally via particular connectors, for interested parties who are unaware of such solutions.
Electric, hybrid, fuel cell, photovoltaic, wind-powered generation systems, power storage, and DC machines are among the applications for the EV Power Distribution Unit. a power distribution system, notably for racks of computers and networking gear in data centres, that is equipped with many outputs. Solutions for power management and protection present difficulties for data centres.
For this reason, a lot of data centres rely on PDU monitoring to boost productivity, uptime, and expansion. Power inputs as large as 22 kVA or even higher are generally needed for data centre applications, which typically have substantially higher power requirements than home or office power strips.
PDUs with 3-phase power input and 1-phase power output are commonly used in large data centres. Basic PDUs and Intelligent PDUs, often known as iPDUs, are the two basic categories of PDUs.
Simple PDUs merely offer a way to distribute power from the input to numerous outlets. Power distribution units with intelligence often have an intelligence module that enables remote management of power metering data, power outlet on/off control, and/or alerts. Certain cutting-edge PDUs enable users to control external sensors like temperature, humidity, ventilation, and other variables.
The Global EV Power distribution unit market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A worldwide vehicle manufacturer has contracted with Eaton’s launched EV power distribution units and Bussmann series fuses for use in a new battery-electric light-duty commercial vehicle, a rapidly expanding market for BEVs. The PDUs can be used with a variety of future vehicles in the portfolio because of their scalable design.
Similar to how a home service panel connects the main power source to each of the branch circuits in the house, PDUs, often referred to as junction boxes or fuse boxes, connect the primary battery power to the rest of the car.
By offering circuit protection, the PDUs perform a safety purpose while delivering power throughout the vehicle. Due to the distinctive characteristics it was able to offer over rivals, including the full integration of the Bussmann series fuses into the PDUs for protection of four auxiliary circuits, Eaton’s eMobility business was awarded the supply arrangement.
A leading truck OEM announced a new commercial partnership with Sensata Technologies to purchase its Power Distribution Units for DC fast charging of electric trucks. Sensata Technologies is a leading industrial technology firm and a producer of sensor-rich solutions that give clients insight.
Sensata’s Power Distribution Units are built with leading contactor, fuse, and control unit technologies from its Gigavac and Lithium Balance product brands, as well as a small, actively cooled design to support 500A (and higher) of charging. They are optimised for heavy vehicle electrified powertrains operating up to 850V.
A significant manufacturer of electric long-haul trucks wanted a solution to offer control and safety for DC fast charging of its newest truck in a safe and dependable manner.
In addition to safeguarding the driver of the car and the batteries, which are sometimes the most expensive parts of an EV, this solution is essential for the safety and equipment longevity of electric vehicles (EVs).
This electricity Distribution Unit (PDU) safely cuts off electricity to the battery system in the event of a short circuit, which can happen in a number of circumstances, such as when a vehicle is hit by another while charging or when the charging connection is defective.
The high voltage contactor and fuse must be used in the right combination for full fault coverage in order to assure electrical safety while the car is being charged.
Sensata’s Power Distribution Unit, which is effectively connected with the proper Gigavac contactor, uses its own GigaFuse technology with pyrotechnic capabilities to offer fast triggering in the event of a short-circuit to address this problem.
Along with fuse and switch technology from Sensata’s Gigavac product line, the PDU also has controller technology from Lithium Balance with embedded software capabilities for high voltage interlock (HVIL), contactor control, and communication of current, temperature, and voltage.
This tactical victory highlights the effectiveness of their integrated technology portfolios from recent acquisitions like Gigavac and Lithium Balance and how this enables us to offer more complete solutions to the customers as they make the commitment to electrify their fleets.
The design of this kind of solution is fraught with difficulties, particularly with regard to the environment’s present conditions, including temperature, space limitations, and cyber security. By including a cooling system in the design, components must satisfy the requirements for current carry and temperature.
The control panel also has to follow AUTOSAR guidelines. A comprehensive solution was created by combining the expertise of Sensata’s professionals in software development, electrical engineering, and mechanical engineering.
The team created a unique control board for use specifically in electrification applications by drawing on the controls expertise and technological know-how from the recently acquired Lithium Balance.
