With rapid development of the automobile industry, the number of electronic control units in the cars have growth dramatically. Till now, the consumer cars are completely electronical from the transmission system and emissions to door locks, climate control and suspension system. Cars are not simply mechanical engines but closely related to everyone’s sa fety, which bring strict requirement of extremely high stability and reliability of on-board storage devices.

Vehicles operate in various unimaginable environments. In addition to considering the requirements of performance, cost and capacity, the on-vehicle SSDs storage devices must be able to meet vehicle-level standards to ensure the stability, durability and reliability in harsh driving situation, such as uncertain changeable temperature, high shock and the electromagnetic interference from environment and other onboard systems.

Challenges Facing Renice SSD

1. Unstable Power-supply In Vehicles

The abnormal power failure will cause problems such as blue screen, disk corrupt, even crush of the entire systems.

2. Effect Of Temperature On Vehicle Systems

Extrem temperature and constant thermal cycling can cause damage and reduce lifespan of in-vehicle SSDs.

3. Complex Running Environment

The unimaginable operting environment can easily caused SSD failure of in-vehicle applications, increased the risk of traffic crash or even more to life safety.

Renice Case Study

1. Customer's Problem

A European manufacturer of in-vehicle data acquisition systems contacted RENICE, hoping to work out a reliable in-vehicle SSD solution for their new product. The device requests 4 high speed rugged 2TB SSDs, needs to process huge data transmission everyday.

They emphasized the data is vital to passenger and traffic safety, besides considering the vibration resistant and great temperature tolerance, the in-vehicle SSD must be ensuring data integrity in any situation.

2. Renice Analysis

Considering the heavy workload behavior, RENICE team provides in-vehicle 2TB MLC SSD with around 3,720TBW lifespan. The vehicle-standard conformal coating processing allows the in-vehicle SSD is resistant to humidity, dust and chemical damages.

RENICE in-vehicle SSD features the exclusive r-Backup technology, equipped with industrial-grade capacitors, power management circuit and related firmware support, 100% ensure the data integrity in any situation, and perfectly meet the requirement for real-time monitoring.

3. Renice SSD Solution

Renice r-Backup Power Failure Protection SSD

◐ Self-developed Patented Technology

Renice exclusive r-Backup technology utilizes the firmware and hardware design, further improved the shortages in most of existing power-failure protection SSD design based on built-in power detection circuit. In case of abnormal power voltage detected, the r-Backup mechanism actives and prevent the incomplete data from being recorded and corrupting valid data on the Renice industrial SSDs.

◐ Ultra Wide Temprature Shock Test: -50°C~+90°C

All in-vehicle SSDs are strictly tested under ultra wide temperature shock cycles from -50°C to +90°C for 72 hours. Coupled with thermal adaptive technoloy, the Renice in-vehicle SSDs are enable to tolerate various unpredicatable demanding environment.
