TITAN Series
Battery Simulator Power Supply
High-Voltage Bidirectional DC Platform for E-Mobility, ESS, and Converter Testing

Programmable Bidirectional DC Power Supply

Developing component prototypes such as inverters for DERs like windturbine and solar farm or EV charging system, onboard chargers and V2G technology research, usually requires validating its reliability and stability in operation when connected with, as what will eventually happen in real world after their implementation, a high-voltage and high-power battery system. However, it is fundamentally unrealistic for any EV manufacturers and energy system integration companies to have at their disposition a real battery systems to which then can connect their products for validating, either for reasons of lack of controllability and the high cost. A battery simulator power supply is what you should rely on by contrast, to achieve better effectiveness and testing sequence automation.

TITAN Battery Simulator Power Supply, with legacy model name of ABS series, is a bidirectional power testing equipment that offers maximum level of 2000 VDC and offers parallel connection options for building testing platform with 10MW as maximum power rating of the same. The system's bidirectionality emulates a battery's operation pattern of both consuming and producing battery from one unit, further supported by smart built-in interfaces and remote softwares for users to configure at their discretion and emulate the required battery charging and discharging profile against their products, along side with versatile options for simulating batteries of various chemical compositions.

Technical data

High Power Scalable Design

Titan DC series supports multi-unit parallel operation and adopts high-speed fiber optic communication technology, featuring strong anti-interference capability and zero latency. The system supports expansion up to 7.5MW by connecting in parallel in 1MW increments from 300kW minimum. It enables multiposition, high-capacity, and multi-voltage level test setups, significantly improving testing efficiency for customers. In particular, the parallel-connected panels can be used in multi-output mode by separating the outputs according to the user's needs, allowing multiple test equipment to be tested at the same time, maximizing user convenience and saving a lot of costs.

Auto Ranging

The auto ranging function automatically controls voltage and current through the programmable DC power supply to maintain the rated output over a wide operating range. That is the higher voltage is available at lower current, and vice versa, allowing the DUT to be tested under different voltage/current conditions with a single DC power supply.

I

n addition, it supports smooth and ultra-fast automatic switching with the bidirectional Automatic “source” & “load” function. The overshoot of voltage or current can be effectively controlled without any delay in the transition between the two states of source and load.

CV/CC Priority Setting Function

CV (constant voltage) priority / CC (constant current) priority mode can be selected and set:

Suppression of Overshoot with CC Priority Mode
With the Titan DC series power supply, the CC priority mode can effectively respond to load variations. This mode suppresses momentary current spikes when the load suddenly changes its resistance, thus ensuring stable protection for sensitive loads.
Configuring the power supply in CC priority mode allows for voltage adjustment according to load changes, maintaining a stable current. This effectively protects sensitive loads such as high-power laser diodes and minimizes the risk of damage due to overshoot.
Current Overshoot in CV Priority Mode
In CV priority mode, the power supply prioritizes maintaining a constant output voltage. However,
sudden load variations can cause momentary current spikes, posing a risk of damage to sensitive
loads.
Therefore, configuring the Titan DC series power supply in CC priority mode enhances load stability
and prevents damage caused by overshoot.

The power supply can not only provide standard power supply environment for electrical equipment, but also receive the energy from load and feed ti back to the grid, with feedback efficiency of above 94%, to save energy and improve the test environment.

Electronic Load

Titan DC series feedback DC electronic load is different from the traditional consumption load. It feeds back the absorbed electric energy to the power grid after transformation to save energy and improve the test environment.
