An EV charging station in Taipei City was officially opened on July 27 by NHOA.TCC, a Taiwan Cement affiliate. It is the first DC/DC charging station in Taiwan that incorporate solar electricity while acting as a kind of energy storage.

The first charging station to use differential charging rates, which make peak hour costs four times higher than off-peak hour rates. Additionally, EV drivers can schedule charging times using the messaging app Line.

The EV charging station costs between NT$28 and NT$32 million (US$0.95 and US$1.08 million) and has two charging heaps that are compatible with CCS1, CCS2, and CHAdeMO standards.

The energy storage system, which is powered by a smart energy management system, has a 145KWh capacity and is equipped with premium ternary lithium ion batteries made by E-One Moli Energy, another Taiwan Cement affiliate.

In order to lessen the load on local power networks, the energy storage system acts as a buffer between the EV charging station and those grids by drawing electricity from them during off-peak hours and discharging it to EVs during peak hours.

Nelson Chang, chairman of Taiwan Cement, claims that the global campaign RE100, in which corporations are committed to going 100% green, has increased demand for renewables and energy storage capacities among Taiwanese industrial customers. Currently, the Taiwanese government wants to install a total of 27 GWh of renewable energy by 2025. Taiwan Cement highlighted that a storage capacity equal to 20% of the total green energy generated would be required for Taiwan to deploy green energy effectively. In other words, by 2025, there should be at least 5GWh of storage deployed.

By the end of 2023, Taiwan Cement intends to add 528.7MWh of storage capacity. By the end of 2020, the company has already installed 164.64 KW of renewable energy capacity, and it is anticipated that by 2025, it will have exceeded 500 MW. These renewable energy sources include solar power, onshore wind, and geothermal energy.
