Electric Vehicles Sensors
CSHV Series
Current Sensors. Current measurement for battery management systems in electrified vehicles (EV, HEV, PHEV, BEV). Current leakage detection and fault isolation in battery charging systems
The CSHV Series are open loop current sensors that use Hall-effect sensing and patented Honeywell technology to bring the best combination of performance and reliability for current sensing applications.
These products are non-intrusive and electrically isolated from the monitored circuit. This ensures a simple sensing method. They are rated for a primary current measurement range of ±100 A to ±1500 A dc.
The CSHV Series is AEC-Q100 qualified to meet higher quality and reliability. For motor control applications, the current measurement is directly proportional to the motor torque. Current measurement can also be used to determine the speed at which the motor is turning. Such speed information can be calculated by understanding how the control algorithm affects the current level.
