EVs represent one of the fastest-growing segments in automotive markets worldwide in recent years and they are projected to expand even more rapidly in the next ten years. For example, in the U.S., sales of electric vehicles rose from just 0.2% of total vehicle sales in 2011 to 4.6 percent in 2021.1
Forecasts for the adoption of electric vehicles over the next decade are influenced by automotive manufacturers’ strategies and governments’ adoption of policies designed to incentivize EV sales, with most projections showing robust acceleration in the adoption of EVs. According to a forecast by S&P Global Mobility, EV sales in the U.S. may rise to 40% of passenger car sales by 2030, while other projections predict EV sales reaching 50 percent by 2030.2
This increase in consumer demand for EVs is being driven by a number of converging factors – environmental concerns by consumers, increased vehicle selection by automakers, enhanced battery capacity, and overall cost savings.
One critical aspect of government support for EVs is the expansion of the infrastructure necessary for widespread EV adoption. For example, the recently enacted Infrastructure Investment and Jobs Act provided $7.5B for developing and expanding the nationwide network of charging stations.3 This investment is primarily directed toward the installation of fast charging stations along U.S. interstate highway system to enable long-distance travel with less range anxiety.4
Suppliers of EV Charging Systems Need Specialized Capabilities
This next generation of EVs, along with the charging infrastructure to support them, will require manufacturers with specialized capabilities to support automakers and their suppliers, as well as the manufacturers and installers of EV charging stations, including municipalities, utilities, parking garages, fuel stations, and retail and office buildings. There will also be demand for residential fast EV chargers.
These capabilities include extensive experience in the design, manufacture, and certification of high-power EV interconnects for vehicle batteries/drive trains and cable harnesses, and other accessories for other internal automotive systems, as well as external connectors for EV charging stations designed to handle larger vehicle batteries with higher amperages to deliver faster charging speeds. An ideal supplier would be positioned to deliver EV charging solutions that could provide customized product deliveries for all the customers mentioned above, as well as provide worldwide management of certification standards.
BizLink Provides A “One-Stop” Solution for EV Charging Systems
As a long-time supplier to major automotive manufacturers, including the top EV brands, as well as makers of electric motorcycles, trucks, off-road and specialized vehicles, BizLink has extensive experience in delivering comprehensive EV charging solutions that meet the stringent requirements of these automotive/vehicle customers. This experience includes wall-mounted and portable EV charging stations, charging couplers, in-vehicle wired and wireless chargers, and docking stations, as well as high-voltage, high-current cable assemblies for EV powertrains.
The BizLink process begins with a thorough analysis of customer requirements for their EV charging device, including the mechanical design of the enclosure, all electronic circuitry, product packaging at all levels (including labeling, boxes, cartons, and palletization), as well as accessories such as cabling and the development of the user manual. In evaluating customer designs, BizLink will often recommend enhancements to the design for increased performance or reduced cost.
Once the design is established, the BizLink engineering team conducts an extensive multi-level analysis before the product goes to manufacturing, including electronic circuit testing and optimization, electromagnetic compliance, thermal management, and mechanical strength. BizLink’s automotive products are manufactured in ISO/TS 16949 and IATF 16949 certified facilities. In addition, these factories have received global certifications to ISO9001, ISO14001, OHSAS 18000, and UL standards.
Worldwide Automotive Certification Standards
After manufacturing, in cooperation with the customer, BizLink conducts worldwide certification and testing services of EV charging devices and other automotive systems to ensure compliance with the stringent requirements of multiple global certification agencies. Compliance with North American and European DC fast-charging automotive interconnects must meet the UL 2251 and IEC 62196 standards established for electric vehicle charging systems. The standards for the charging interface include CCS-1 (North America) and CCS-2 (Europe) that are air-cooled charging connectors rated to 300A DC current, and liquid-cooled CCS-1/2 devices rated for a minimum 500A DC.
Portable EV charging systems must include an overheating protection mechanism and meet the IP67/NEMA Type 3 enclosure rating for safe outdoor use. In addition, the charge couplers (interfaces with the EV charging ports) for these portable devices must comply with the standards SAE J1772, IEC 62196-2, and GB 20234.2 based on the geographic region in which they are sold.
BizLink has the capability to conduct a series of more than 150 tests on EV charging systems and components to ensure that compatibility, reliability, and safety compliance meets all the relevant global automotive standards. With an extensive network of local representatives for certification applications in more than 35 countries (including the European Union, United Kingdom, Canada, and others), BizLink has the capability to ensure that certification testing is completed before delivery to the customer.
