Advanced Test Solution for New Energy Parts – Chroma Multi-Channel Battery Simulator

Chroma ATE Inc. was invited to attend the IFEEC 2017 (International Future Energy Electronics Conference) held in Kaohsiung to introduce the new product for battery simulation. The battery simulator can perform simulations on the units that are critical to the booming EV industry such as DC charging pole, on-board charger, and DC/DC Converter, etc. for product verification.

As more and more energy conversion products such as motor driver, OBC, DC/DC convertor, and power conversion system (PCS), etc. use battery as the power source, a battery simulator is required for product quality verification. Battery suppliers may not be able to supply batteries of various kinds such as flow battery, sodium sulfur storage battery, and lithium-ion battery with different charge/discharge characteristic curves during product development.

The battery characteristic is nonlinear which is easily affected by temperature, charge/discharge current, aging cendition, and efficiency ,cannot replicate the same characteristic for repeat testing. As time is required to charge or discharge a battery, it makes instant output voltage change impossible for the real battery, which is quite inconvenient when testing the power converter’s upper and lower limits. Most importantly, the large capacity battery is big in size and will age after long-term use. It costs a lot for replacement, plus if the battery is damaged, overcharged or over discharged. It could easily cause safety hazards. In the lab, it is not recommended to set up large capacity batteries, but rather to use a battery simulator for testing.

What functions are required for a battery simulator?

  1. Battery internal resistance setting: The main task of a battery pack is to provide energy to the developed products. When the charged/discharged current is added to the battery pack, the voltage of the battery pack changes instantaneously in a short time due to the impact of the battery internal resistance.
  2. Battery capacity setting: The DC input voltage operating range should be clearly specified in the developed product specification, which is related to the battery pack capacity and output voltage.
  3. Battery voltage point setting: The usage of the battery pack varies with products, and the frequently seen battery management items are 6 voltage level including overcharge voltage, over discharge voltage, upper limit operating voltage, lower limit operating voltage, full charge voltage, and full discharge voltage.

Chroma’s multi-channel battery simulator is easy to use. The multiple embedded channels can test different DUTs at the same time, and read the test results in real time. The rapid setup of common battery parameter can simulate the charge/discharge voltage and IR state of a battery cell under normal, high and low temperatures. The battery cell parameters can convert battery pack state to set the operating and protection range. Moreover, it can set the initial state of output voltage for product testing and verification without waiting for the charge and discharge time like the real battery pack.

Chroma ATE Invested Innovative Nanotech Inc. with Technology Transfer from ITRI to Advancing in Semiconductor Front-end Process Inspection

TAOYUAN, Taiwan, Nov. 24, 2017 — Innovative Nanotech Inc., invested by Chroma ATE Inc., signed a contract with Industrial Technology Research Institute (ITRI) on Nov. 24 for “Nanoparticles Monitoring Technology” transfer. In addition, ITRI will serve as an important shareholder of Innovative Nanotech. Just a short time ago Innovative Nanotech had been contracted with Hsinchu Science Park for the purpose of developing and creating liquid nanoparticle monitoring systems used in the semiconductor manufacturing process to help improve the yield rate.

Large amount of liquid solutions are often used to clean, grind and etch the wafer surface during the semiconductor manufacturing process and impurities in the solution have an impact on the defect rate. Light scattering particle measurement technology currently cannot precisely detect the size and quantity of solution particles under 20nm, which makes it difficult in controlling the manufacturing process. Also, with development from 20nm to 10nm and even to 7nm, the minimized transistors make the width of current path narrow; therefore, when impurities like nanoparticles appear in solution, it will affect the defect-free rate of the product.

Innovative Nanotech will introduce to semiconductor manufacturers a new generation nanoparticle monitoring system, SuperSizer, which will accurately detect the size and quantity of particles above 5nm. This will allow manufacturers to take necessary measures to improve the process according to the monitored results. In addition to the semiconductor manufacturing process, this technology can also be applied to electronics, optoelectronics, and biomedical materials fields.

Innovative Nanotech will expand to a global market by incorporating the sales and marketing channels of Chroma group. Chroma ATE Inc. is a world leading supplier of Automated Test Systems, Intelligent Manufacturing Systems, Turnkey Test and Automation Solutions and has a number of back-end precision measurement product lines in the semiconductor testing field. Innovative Nanotech will become Chroma’s semiconductor front-end process testing solutions provider to satisfy the testing requirements of a complete semiconductor manufacturing process.
