Connolly, CEO of Siemens Australia Pacific and head of Siemens’ Smart
Infrastructure portfolio in the region said, “We’re proud to see our technology
play a pivotal part in fulfilling New Zealand’s low carbon future. It’s
critical to have a long-term view of transport infrastructure – one that
centers around the effective and efficient use of the right technology and
seamless movement of people.”
The charging system in the Christchurch depot will consist of 12 Sicharge UC 200 Charging Centers with dispensers powering 25 parking spaces with up to 200 kilowatts (kW). In Auckland, there will be five of these systems as well as two Sicharge UC 100 stations with a charging power of up to 125 kW, supplying a total of nine eBuses. Both solutions provide plug-in depot charging, according to CCS standard, overnight or for top-up charging between scheduled bus services during the day. The Sicharge UC family supports battery voltages from 10 Volt (V) up to 1,000 V. Current eBuses available in the New Zealand market average between 600 to 700 V, but future bus batteries are expected to use higher voltages to enable faster charging. Additionally, the charging system uses open communication standards as Open Charge Point Protocol (OCPP) to interact with different backend software, for example for charging management.
The reporting and monitoring function of Siemens’ charging management software will enable Go Bus to centrally monitor all charging infrastructure across two cities and easily report on key metrics including electricity savings. Smart management functionality will also enable Go Bus to schedule charging to take advantage to lower overnight tariffs while ensuring that individual buses have reached the desired state of charge by the time they are needed for the next day’s operations.
