POWERFUL PARTNERSHIPTAI YIAEH × HOTAI DAIKIN

Next-Generation 360–720 kW
Ultra-High-Power EV Charger
Liquid Cooling Distribution Unit (CDU)

Built for ultra-fast charging sites, this advanced thermal management solution protects both the system's "brain" and "heart" by moving the high-vibration, high-heat cooling core out of the charger cabinet—significantly extending the service life and reliability of high-voltage power modules.

Eliminates dynamic thermal shock and low-load ice build-up—providing the most reliable physical protection for ultra-fast charging sites.

Industry Pain Points

Embracing the Ultra-Fast Charging Era
The Limits of In-Cabinet Air Cooling Are Reached

As charging power advances from 360 kW toward 720 kW, the internal AC/DC power modules generate massive heat at full load—4%–5% of total power (approximately 15–30 kW)—far beyond what the charging gun and cable alone dissipate.

Cabinet Space Constraints

Traditional "built-in compact chillers" are limited by cabinet space, and compressor vibration directly impacts the lifespan of precision electronics.

Cliff-Edge Dynamic Thermal Shock

Rapid power switching the instant a vehicle plugs in or out overwhelms traditional cooling systems—constant-temperature control fails completely.

0 kW ⟷ 24 kW　Instant Switching

Low-Load Ice Build-Up / Overheat at Full Load

Sluggish response easily leads to low-load ice build-up, while full-load overheating triggers shutdown—both are critical failures.

Core Technology · Patent Moat

Three Technology Shields

More than cooling—industrial-grade reliability engineering.

Robust Cooling Source Array

Powered by a Daikin inverter condensing unit as the cooling core, with excellent all-weather outdoor durability. The split architecture moves the high-vibration compressor outdoors, leaving only piping and heat-exchange interfaces inside the charger cabinet.

Integrated Daikin Inverter Condensing Unit

Dynamic Feedforward Control Algorithm

Abandoning slow single-loop PID, our proprietary "feedforward predictive control logic" monitors the rate of temperature change in real time and responds within seconds—handling both instant full load and transient low load (trickle charging).

Patent Application No. 115105937

Vacuum Flow Protection

All piping is welded with semiconductor- and aerospace-grade stainless steel craftsmanship, combined with a pressure-balancing mechanism to fully prevent air bubbles and pipe stress rupture. Comprehensive high-pressure and vacuum leak testing keeps microchannels clog-free and rust-free.

0 ↔ 24 kW Dynamic Switching
with Full Outlet Temperature Control

The blue line is the charger outlet temperature; the red line is the charger output percentage (Charging Mode 100% = 24 kW, Standby 0 kW). Under a full day of repeated cliff-edge 0↔24 kW thermal shocks, the outlet temperature remains fully controlled—no under-temperature, no overheating.

Next-Gen Strategy

From Standalone to On-Site
Centralized Liquid Cooling Distribution CDU Hub

01
Cooling Pooling
5–10 fast-charging cabinets no longer need "one chiller per charger." Multiple Daikin inverter condensing units run in parallel while a central controller pours cooling capacity to each charger based on its real-time kW demand—dramatically reducing build-out costs.
02
Active Redundancy and Seamless Failover
If any single cooling unit fails, the hub automatically isolates it and dispatches the remaining units to over-clock in support—chargers keep running with zero downtime, meeting Charge Point Operator (CPO) requirements for high availability (HA).
