GYS launches first 200 amp battery support unit
Over the last 20 years, the demand for robust battery support in modern vehicles has escalated sharply. In the early days, workshops relied on basic battery chargers, which were sufficient for vehicles with minimal electronics and no need for a stable voltage stability. As ECUs, and safety systems became widespread from the 1990s onwards, voltage drops during diagnostic and programming work began to cause faults, data loss, and corrupted control units, highlighting the need for more stable power delivery.
The earliest battery support units, emerging in the early 2000s, typically delivered around 25 A of power and offered minimal functionality. Today, the industry understands much better the demands placed on a vehicle’s battery when the vehicle is in a “key-on-engine-off” state.
Why higher amperage is now essential
As vehicles and their onboard systems get smarter over time, battery support units have had to become smarter too, transforming from simple chargers into high-precision power supplies essential for modern automotive workshops.
Advances in electronics, increased sensor loads, infotainment systems, ADAS, and related subsystems mean that current draws of 20 A, 40 A, or even 100 A or more are no longer unusual. In fact, many OEMs now specify 100 or even 120 A for battery support during programming or diagnostics. This upward trend underlines the need for future-proofing as vehicles continue to evolve.
GYS, a leader in professional battery support and charging equipment, has been at the forefront of this evolution, setting the industry standard with 100 A, 120 A, and now 200 A battery support units.
Reaching the limits of single-phase power
Such is the demand from vehicles that we are pushing the boundaries of what a standard 13 A plug can deliver. To put it into perspective, 120 A of battery support is already drawing close to the physical limits of a single-phase supply. As OEM demands continue to increase, the prospect arises that future battery support could require a 3-phase power supply, which would introduce an entirely new set of challenges and inconvenience for workshops where single-phase power is the standard.
However, GYS has overcome this challenge with the GYSFLASH 200 CNT – the first battery support unit able to deliver 200 A on a single-phase supply.
How is this possible? GYSFLASH 200 CNT
A 200 A battery support unit represents a significant leap; Achieving this from a single-phase source is extremely challenging with conventional designs. But by borrowing technology from GYS’ advanced robotic automation and integrating its CNT (Connected) architecture, the GYSFLASH 200 CNT achieves this breakthrough, delivering the highest capacity of battery support yet seen in a single-phase system.
The unit is compatible with all common lead-acid (gel, AGM, liquid, calcium) and lithium (LFP) battery types, with multiple advanced functions built in, such as flexible voltage, cable calibration, charging profiles and more. Automatic 8/9-step charging curves also ensure fully optimised charging that helps to extend the lifespan of the battery.
Connected technology enabling innovation
CNT (Connected) technology, introduced in 2020, allows for seamless connection of chargers and computers, while offering full traceability and software updates. CNT technology has already enabled innovations such as 16 V support for Tesla systems and 24 V battery balancing solutions for commercial vehicles, solving battery imbalance. Now, it has led to the next milestone: 200 A, 12 V battery support on a single-phase supply.
As vehicle technology continues to advance, the demand for reliable, high-capacity battery support will only grow. With the GYSFLASH 200 CNT, GYS has not only met this challenge but redefined what is possible – delivering 200 A from a single-phase supply through connected technology and advanced engineering. It sets a new benchmark for workshops to stay ahead of the curve.
