Intelligent charging system
When a depot is converted into an electric depot, new electrical power needs arise in the facilities. Jema can provide a smart charging system to reduce and optimise the power needed.
This is a control centre that efficiently manages all charging conditions/restrictions in the depot. The system identifies the different charging requirements of each bus in order to optimise the total power required.
It also has the following functions:
Smart charging functionality is included with the premium chargers. On the contrary, a device must be acquired separately to have this functionality in the standard solution.
Opportunity chargers for heavy-duty vehicles
Powers of 300 kW, 500 kW and 600 kW
Fast charging systems with a power range from 300 kW to 600 kW are recommended when the vehicle does not have sufficient autonomy to complete the service and needs to make fast charges during the journey.
Charging stations for this type of opportunity chargers are placed at strategic points in cities. This makes it possible to charge several buses or lines. Normally, stop points at the end/beginning of the line are used to charge up to 85% of the battery in minutes.
The power ratings of the Jema chargers vary between 300 kW, 500 kW and 600 kW.
As with the slow-charging systems, the opportunity chargers are bi-directional, enabling G2V and V2G energy flow. Charging is carried out in accordance with ISO15118. They also have remote data access via Modbus TCP/IP or OCPP1.6 protocol.
The fast charging systems are approved for indoor and outdoor installations.
The connection of fast chargers to up/down pantographs allows installations and bus lines to be adapted to the needs of each customer.
Each of the options offers a series of advantages such as automated charging, space and vehicle consumption savings or versatility in the charging process, for example.
Jema also offers a turnkey system in order to install the opportunity charge connected to the medium voltage network and the certificates required by the electricity operators.
