A component that maintains track of time in an electric vehicle is called an EV (Electric Vehicle) real-time clock module. It is a particular kind of clock module made for use in electric cars that can continue to run even when the car is off or removed from the power source.
The onboard computer system of an electric vehicle usually includes a small electronic component called the EV real-time clock module. Even when the vehicle is not in use, precise timekeeping is maintained using a battery backup.
The real-time clock module plays a crucial role in electric cars by assisting in ensuring that the charging system is running properly. It can also be used to track and record how the car is used and how it performs over time.
Global EV real time clock module market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Real-time clock module made by SparkFun called RV-1805 (Qwiic). Due to its ultra-low power consumption, this RTC module can substitute a supercapacitor for a standard battery as a fallback power source. It has a low power RC-based oscillator and two internal oscillators, including a tuning fork crystal operating at 32.768 kHz.
Every few minutes, the RC oscillator can be corrected using the more accurate crystal by switching between the two. The RV-1805’s hardware-defined I2C port is 0x69. To communicate with numerous RV-1805 sensors on a single bus, a multiplexer/Mux is needed.
The Micro Crystal Real-Time Clock Module is an additional RTC module. It is utilised in EV charging stations to conserve energy and offer precise and reliable timing. The RTC module has an increased temperature range (-40 to +125°C) and a precision of 8 ppm over T in terms of time.
It can maintain time even when the MCU is in standby mode and uses extremely little power. The RTC module is in sync with the EVSE’s smart meter, enabling intelligent operation based on pre-programmed charging settings (TOU, off-peak hours), and it can enable edge computing with trustworthy reporting from the EV charging node.
Additionally, Micro Crystal provides a selection of RTC modules with incredibly low power requirements, high precision, and small packages.
A brand-new product, the RV-1805-C3, features an I2C interface, ultra-low power usage of 60 nA, and high accuracy of 2 ppm. Its compact package measures 3.7 x 2.5 x 0.9 millimetres and its temperature range is broadened to +85°C.
