Infinix teased its upcoming 180W Thunder Charge system earlier this week, now the company has revealed more details about it. Unlike the 160W Ultra Fast Charge system we saw last year (which was just a concept), Thunder Charge will hit the market later this year – it will make its debut on a flagship phone yet to be announced.
The goal for the new 180W charger is to get a battery of 4,500 mAh to 50% charge in just four minutes. As on the Infinix Note 12 VIP, there will be a Furious Mode, which charges at maximum speed, and Normal mode, which is still fast but keeps temperatures lower.
Infinix has revealed extensive details about the Thunder Charge system. It will use two 8C batteries connected in series so that each only needs to handle 90W of power. This is still a lot, so there are several layers of protection and efficiency improvements to keep heat generation to a minimum.
First, Infinix worked with leading battery manufacturers to create a multi-electrode air design, which reduces the battery’s internal resistance by more than 50%. Those two batteries are powered by three charging pumps with 99% conversion efficiency (the best Infinix has used so far). These things reduce the heat generated, but it is not enough to ensure safe operation.
The Thunder Charge system has 111 software and hardware security mechanisms. They are on the lookout for things like high temperature, increased voltage, electromagnetic interference and so on and will stop the charging process if something goes wrong.
There are 20 temperature sensors that monitor the USB port, charger chips, battery and other key locations. The system tries to keep the phone’s temperature below 43 ° C to reduce the battery deterioration.
To ensure that the charging cable can handle the load, Thunder Charge will use a special encryption chip to verify the cable’s authenticity. Other cables can be used, also the Infinix charger can be used to charge other devices – however, the power is limited to 60W or 100W in those cases. USB Power Delivery relies on a similar system to test the cable’s capabilities.
Thunder Charge has received a TÜV Rheinland Safe Fast-Charge System certification. The first phones with Infinix’s 180W fast charging system are coming in the second half of this year.
