As a core model within the lithium battery trade, EVE continues to make efforts within the subject of automotive electronics, offering a wide range 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 automobile keys to satisfy the wants of lengthy cycle life within the vehicular atmosphere. Remarkably airtight, dependable, and protected batteries result in larger effectivity, larger stability, and longer working time of automotive electronics. 

e-Name/T-box Standby Battery Options

Lengthy-life rechargeable Li-ion batteries (PLM collection) have the traits of excessive energy and vast working temperature vary, with the ability to assist e-Name/T-box purposes 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 formulation). These samples had been nonetheless in a position to 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 preserve excellent low-temperature discharge efficiency.

EVE’s Li/MnO₂ batteries, PLM collection, SPC collection, 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 beneath full consideration of the automotive electronics’ energy wants; all collection have handed the security certification of GB/T 38444 and AEC-Q200 to ensure the security of automotive electronics.

To this point, greater than 270 million EVE batteries have been utilized in automotive electronics worldwide.

Word: The entire above knowledge comes from EVE’s laboratory.
