The P16800 simplifies the retrofitting of rail vehicles with control systems by safely (SIL2/SIL4) doubling of speed sensor signals for odometry systems.
During battery testing, charge and discharge processes, (the battery cycles), are continuously simulated on the battery in a HIL (hardware in the loop) configuration, corresponding to typical usage profiles during operation of the electric vehicle. A number of parameters are measured, including capacity, battery efficiency and self-discharge.
Knick offers high isolation transducers for voltage and current measurements. The P45000 is the most space-saving high-voltage transducer with SIL 2 for DC voltage measurement on-board of all DC and AC powered trains.
Substations for DC power supply, rated as high as the upper single-digit MW range, and the grid sections they supply must be effectively safeguarded against short circuits. The protection mechanism must reliably interrupt high levels of current as quickly as possible, limiting the power that flows into the short circuit.
Energy storage with batteries and hydrogen technology is the handshake between renewable energy and e-mobility and critical for growth and continuous development of both technologies.
Le nouveau détecteur de tension P52000VPD (Voltage Presence Detection) assure une surveillance fiable des zones à haute tension et envoie un signal à la commande de l’installation en aval lorsqu’une valeur seuil définie est atteinte.
The test cells used in the manufacturing process are often guarded by safety fencing and voltage presence detection.
For battery-electric vehicles, high-speed charging by way of pantograph is possible. This involves contact between infrastructure equipment (with moving pantograph) and stationary charge-bars on the roof
of the vehicle. A DC switch box on roof of vehicle contains components that verify successful charge connection, and connects with other onboard systems.
The production process of HV Heaters involves many steps, with some of them being manual. Various tests are carried out in-line, according to the corresponding manufacturing stages.
HIL testing allows for prototype designs of equipment like traction inverters to be evaluated in various battery, load and fault situations, without the need to perform the trials with the inverters installed in dynamometers or the vehicles themselves.
