Challenges and limitations of CCS

In order to achieve widespread adoption of electric vehicles, we must address certain challenges and limitations. These challenges and limitations are faced by the Combined Charging System despite its many advantages.

In America, businesses adopting CCS and building out charging stations have provided spotty service, leading to one in five charging attempts failing. This is usually due to charging stations unable to authenticate the consumer’s payment. As a result, many EV makers are adopting NACS, which currently is the gold standard of charging.

Limited charging station availability is another issue. Although the number of CCS charging stations is increasing, there are still regions and market segments with limited infrastructure. This can be a barrier for potential EV owners who rely on public charging stations or cannot access home charging. Another challenge is the cost of deploying CCS charging infrastructure. Building and maintaining charging stations can be expensive, especially for smaller charging network operators. This cost can deter charging station operators, leading to slower infrastructure expansion.

Regarding limitations, CCS charging speeds depend on the charging station’s power output and the electric vehicle’s capabilities. DC Fast charging can charge at speeds of up to 350 kW. However, not all EV models can take full advantage of this power level. Some EVs may have lower charging capabilities, limiting the charging speed.

Future prospects and advancements in CCS technology

The Combined Charging System has made significant progress in transforming the process of charging electric vehicles. Despite this, most prominent automotive manufacturers have agreed to support Tesla’s North American Charging Standard in the United States.
