Tribrid Energy Storage System
A Next-Generation Energy System that Connects Solar Cells, EVs/PHVs and Storage Batteries
Based on the Company’s accumulated technologies and track record related to power storage systems and EVs and plug-in hybrid vehicles (PHVs), NICHICON has developed an altogether new next-generation energy storage system for connecting solar cells with EV/PHV batteries and storage batteries, the “tribrid energy storage system.”
Tribrid Energy Storage Systems
The next-generation energy system NICHICON has developed—the tribrid energy storage system—efficiently connects solar cells, EV/PHV batteries and storage batteries, creating a total energy system that can be used in a variety of scenarios. The electricity generated by solar cells can not only be used in the home or stored, but it can also be used to run EVs. A highly efficient system that provides a DC link to three batteries enables the movement of electricity between storage batteries and EV batteries. As a result, when an EV is not present, the power from solar cells can be stored in storage batteries. When the EV returns, the stored power can be transferred from the storage batteries to the EV, enabling carbon-free vehicle operation. In addition, in the event of a power outage, the storage battery and the EV’s large-capacity battery can be used as backup, providing even greater peace of mind. This system enables an extremely high level of self-sufficiency based on solar power generation for both homes and vehicles.
Features
- The electricity generated from sunlight is stored in EV batteries and storage batteries, enabling household power consumption. In addition to being used in the home, the solar power generation can be used to run EVs, resulting in a total energy system.
- A highly efficient DC connection between three batteries—solar cells, EV batteries and storage batteries—minimizes the conversion loss, facilitating the movement of electricity (Elemove) between storage batteries.
- Consolidating three power converters—for solar cells, storage batteries and vehicle-to-home (V2H) systems—into one saves space.
- We expect to respond to new certification*2 facilitating the free combination and increase of solar cells, storage batteries and V2H systems at a later date.
- As users’ life stages change, they can upgrade the system by adding solar cells, adding storage batteries or increasing V2H stand connections.
- In the event of a power outage, storage batteries and EVs can instantaneously supply power to homes, contributing significantly to peace of mind. Power generated by mid-day sunlight can be stored for use at night, providing peace of mind, and power from storage batteries can be used to charge EVs.
- We expect the system to facilitate the offering of new services, by enabling control of a variety of travel modes with a single remote control, facilitating protection even without an HEMS (Home Energy Management System), facilitating the control of PV power output, complying with fiscal 2017 VPP restrictions, and allowing network app downloads.
UXY Series of Vibration-Resistant, Lead-Type Aluminum Electrolytic Capacitors
NICHICON has applied its simulation technology toward the development of the UXY series of lead-type aluminum electrolytic capacitors. These capacitors utilize a high vibration-resistant structure that is optimized for vibration required by the market for automotive applications.
Features:
As in-vehicle applications require high capacity, product sizes increase. However, as product size becomes larger, the vibration resistance tends to decrease because of an increasing amount of stress placed on the lead terminal bases. To solve this problem, Nichicon employed a new, proprietary structure to realize a larger-size product (φ18 x 31.5L, φ18 x 40L) able to handle up to 40G of vibration acceleration and high temperatures of 125°C and 135°C.
