20130229143 | MULTI-PARTY COMMUNICATION CONTROL SYSTEM AND CHARGE PROCESS OF DC CHARGING SYSTEM - A multi-party communication control system and charge process of a DC charging system is provided. According battery pack information transmitted by a battery control system, a multi-party communication control device determines a charge current or a charge voltage and a voltage-controlled charge mode required by a battery pack. The multi-party communication control device then translates the charge voltage or the charge current to a CHAdeMO language that is next transmitted to a CHAdeMO charger. | 09-05-2013 |
20130271065 | HIGH-VOLTAGE BATTERY CHARGING SIMULATION SYSTEM AND OPERATING METHOD THEREOF - The present invention relates to a high-voltage battery charging simulation system that includes a simulation high-voltage battery pack, a simulation battery management system, a multi-party communication device, and a charging station. The voltage of the simulation high-voltage battery pack can be calculated and updated immediately by the simulation battery management system to simulate the feature of real battery pack, so that it can detect the operation of the multi-party communication device and the charging station. | 10-17-2013 |

20130063044 | LED ILLUMINATION SYSTEM - An LED illumination system includes a DC power supply, at least two LED illumination lamp sets and at least two power circuits corresponding to the LED illumination lamp sets. The DC power supply provides sufficient electric power for the LED illumination lamp sets and is connected to the LED illumination lamp sets via the power circuits. The invention supplies electric power required by the LED illumination lamp sets via a single DC power supply without an extra DC power supply, hence the cost is lower. Moreover, the DC power supply is located remote from the LED illumination lamp sets, hence high temperature generated by the DC power supply does not affect lighting and lifespan of the LED illumination lamp sets. The hazard of electric shock by inadvertently touching the AC power source while replacing lamps in the LED illumination lamp sets can also be avoided to improve safety. | 03-14-2013 |
