[Dry goods] Analysis of whether 12V traditional power battery will die

Hyundai has made a big gimmick, and Ioniq Hybrid has become the world's first car to remove 12V conventional batteries. HyundaiIo niq Ditched Its Traditio nal 12V Lead-Acid Starter Battery has a 2.4% increase in weight reduction of 11.8kg.

In fact, a closer look, modern engineers in the hybrid battery to replace the 12V AGM battery with a lithium battery, and then put together by integration, to achieve a hybrid integrated battery system.

This lithium battery module is placed on the side of the high voltage battery, rated voltage 12.8V (estimated 4S4P), 30Ah, rated output power 1.8kW.

If Ioniq is compared with the Prius4, one uses 1.56 kWh and the other uses 0.75 kWh. In the high-speed segment fuel efficiency and integrated MPG mode, the counterattack against the Prius is achieved.

DCT and ECVT continue on the system at PK

In the EV version, the 12V AGM battery is still in use.

The technology changes are still a little faster. If you look at it, it is not good news for the manufacturers of traditional lead-acid batteries and AGM batteries. Many of the considerations we know about the 12V control system will be refurbished. Start with a head and continue to explore the system control technology brought by this change, even the DCDC, power Distribution Box , 12VBMS management design changes.
