The event of massive knowledge and 5G has given rise to vehicle-to-everything. Nevertheless, the particularity of onboard functions put ahead extra stringent necessities for battery provide (As proven in Desk 1).
As a core model within the lithium battery trade, EVE continues to make efforts within the subject of automotive electronics, offering quite a lot of battery options for automotive electronics, which embrace coin-type and cylindrical-type batteries.
EVE battery options are extensively used within the fields of ETC, e-Name, T-box, TPMS, GPS monitoring, and automotive keys to satisfy the wants of lengthy cycle life within the vehicular setting. Remarkably airtight, dependable, and protected batteries result in greater effectivity, greater stability, and longer working time of automotive electronics.
e-Name/T-box Standby Battery Options
Lengthy-life rechargeable Li-ion batteries (PLM sequence) have the traits of excessive energy and vast working temperature vary, having the ability to help e-Name/T-box functions all day in all conditions.
To simulate the lifespan efficiency of PLM merchandise, PLM18650 samples had been saved at 85℃ for 100 days (which is equal to fifteen years’ storage at 40℃ based mostly on the empirical method). These samples had been nonetheless capable of attain a 13.7W peak pulse at -20℃ (one of many typical e-Name discharge profiles). As proven in determine 1. Even after long-term storage at excessive temperatures, PLM batteries can nonetheless keep excellent low-temperature discharge efficiency.
TPMS Battery Options
Li/MnO₂ high-temperature coin-type batteries present a great battery answer for onboard TPMS to make sure protected travels.
The high-temperature efficiency of CR2032HT at 105℃ is proven in determine 2.
Automobile Key Battery Options
The excessive pulse voltage platform and excessive pulse capability of Li/MnO₂ coin-type batteries present longer service life for automotive keys. Based on determine 3, CR2032 coin-type batteries had been examined over 49,000 discharge instances with 15mA pulse at 20℃, which suggests it could actually assure 5+ years lifespan for automotive keys.
GPS Monitoring Battery Options
Li/MnO₂ cylindrical batteries have the options of excessive security, excessive reliability, and excessive pulse capability, which may escort the real-time positioning and monitoring of automobiles. As proven in determine 4, CR123A batteries can discharge over 2000 instances with 900mA pulse at 20℃, which may meet the correct positioning energy wants of GPS monitoring units.
Conclusion
EVE’s Li/MnO₂ batteries, PLM sequence, SPC sequence, and ER+SPC options have some great benefits of ultra-wide working temperature vary and high-performance sealing know-how that may present ultra-long time energy provide stably in automotive electronics software situations.
EVE batteries had been designed and produced below full consideration of the automotive electronics’ energy wants; all sequence have handed the protection certification of GB/T 38444 and AEC-Q200 to ensure the protection of automotive electronics.
Up to now, greater than 270 million EVE batteries have been utilized in automotive electronics worldwide.
