Cervoz SSD Storage Solutions for Smart EV Chargers

Cervoz Technology Co., Ltd. helps the EV charger providers to deliver a smart EV charger solution to their partners and users.

Transportation is going electric
As governments successively announce policies targeting zero-emissions transportation, electric vehicles (EVs) are now snowballing in global popularity and market, around 160% increase in sales in 1H021 compared to 2020, and is estimated to keep expanding for the upcoming years ^(*). While the popularity and market of EVs continue to rise, so do electric vehicle chargers.

Interconnected smart EV charging
Interconnectivity is trending in transportation, such as vehicles to home (V2H), vehicles to grid (V2G), even vehicles to everything (V2X). The trend has shaped the development of EV charging from fixed-point stations to widespread interoperable units, from standalone to interconnected Smart EV Charging devices.

Smart EV chargers are interconnected while sharing a data connection with electric vehicles and their operators. The interoperability allows vehicle owners to track charging progress remotely and know nearby chargers’ vacancies during their drive. In addition, interconnected EV chargers allow operators to conduct cloud-based and scalable management, real-time monitoring, remote software update, and optimize electricity distribution.

Challenges and Cervoz solutions

Since drivers who use EV chargers are usually active, dynamic, and on-the-road, status information from a Smart EV charging device such as vacancy and malfunction is required to be real-time, prompt, and reliable. Thus, the Smart EV charging operators who can provide instant and reliable services are able to maximize operational benefits and attract more EV drivers to use their service.

T405 M.2 2280 SSD

The company’s industrial embedded modules are able to assure the data transmission in real-time and reliable. The T405 Family, are a series of SSD products compliant with PCIe Gen 3×4, available in M.2 2242 and 2280 form factors. The NVMe compliance enables the series to read and write at their maximum speed. The T405 Family uses 3D TLC flash memory from Micron to achieve smaller cell sizes, higher circulation speed, and power efficiency. There is also the T435 Family who owns all the above features and comes with a specially designed DRAM buffer to optimize storage endurance and lifespan.

Most of the EV chargers locate outdoor, facing diverse weather. Meanwhile, electrical equipment as such is usually with high operating temperature.
The firm’s flash modules support operating temperatures from -40˚C to 85˚C, enabling them to work within extreme environmental conditions. Also, an in-house developed conformal coatingis optional and compliant to all company’s embedded products, protecting storage against outdoor environment challenges such as moisture, dust, thermal shocks, and sunlight.

The firm offers solutions for overheating, including the Dynamic Thermal Throttling mechanism, which activates automatically to cool the device down. On the hardware front, the firm provides additional heat dissipation solutions for high data transmitting products like T405 and T435.
