The 17020/17040 Regenerative Battery Pack Test System equipped with battery charge/discharge motor and battery simulation functions can be used to test battery packs and other connected associate products. The battery simulator software simulates the working state of an actual battery under different SOC (state of charge), and adjusts the required battery output as desired. It does not have to wait for charge/discharge time to end like the actual battery pack. The 17020/17040 is suitable for verifying the products that work with battery such as the motor drive for car start-stop system, electric controller for light electric vehicle, and on-board chargers, etc.
When developing a product, it must meet various applications for validation; and connecting to different battery packs for verification is a better way to validate the product. However, it is difficult to obtain all batteries, as the batteries from suppliers are either not ready or very expensive when the parts are in the design phase. Thus, using a battery simulator is the best way to solve the issue.
V2G (Vehicle-to-grid) is the newest technology for EV charging. Since at any given time 95 percent of cars are parked, the batteries in electric vehicles allows for electricity flow from the car to the electric distribution network and back. V2G describes the correlation between electric vehicles and the power grid as deriving the necessity of bidirectional on board charger and bidirectional D/D convertor. The trend for vehicle parts design is bidirectional thus the integrated source/load cannot be used to validate this kind of products as the current transition may be interrupted during charge/discharge. The best way is to use a battery simulator to verify the products.
Dual Mode Switch
- Charger/Discharger mode: Using Battery Pro software, it can inspect power battery packs.
- Battery simulator mode: Using Battery Pro software, it can test motor drives/charging stations.
Battery Simulator Hardware
The battery simulator of Chroma 17020/17040 is structured under a regenerative battery pack test system with CC/CP/CP discharge operating modes in 20V, 60V, 100V, 200V 500V and 1,000V ranges. Multiple channels can be paralleled to increase current as desired for battery pack simulation. It gives users flexibility in utilizing the equipment. The test system has seamless and rapid charging and discharging transition function that can simulate the battery’s actual use status for testing bidirectional parts. Its optimized energy regenerative design saves the electricity and air-conditioning cost. For example, the charging energy can turn back to the power plant for direct use when the on-board charger charges the battery.
