The net zero emissions ambitious targets push the OEMs to speed-up the xEVs development and shorten the Time-to-Market strategy as the transportation is one of the key pillars of this initiative. Adopting the xEVs by a large part of the population represent a hurdle for the OEMs and force engineers to tackle the sensitive topic of the range anxiety brought by using Li-Ion batteries.

The engineers defined, throughout complex algorithms, two key parameters: SOC (State-of-Charge) and SOH (State-of-Health) computing by the BMS (Battery Management System) steering device of the battery pack. The SOC, well-known by the driver as represented on the dashboard by a nice gauge icon, is defined as the ratio of the available capacity and the maximum possible charge that can be stored in a battery. The current flowing in and out of the battery is the paramount information to have the SOC as accurate as possible.

Therefore, the current sensor is playing a key role in estimating and extending the autonomy of the battery leading gradually to gain the trust of the customers to adapt xEVs and step electrification forward.

CAB series

The CAB series, is the best-in-class current monitoring solution for high voltage battery pack. It offers 500A and 1500A DC current ranges being compliant with the ISO 26262 (Road vehicles – Functional safety ISO 26262-2018 Ed.2).

LEM introduced the first version (300A range) more than ten years ago allowing to capitalize on the knowledge at the same time than OEMs. Today, LEM releases the third generation of its solution by increasing the range at +/- 1500A and keeping the same level of accuracy (

The compact high precision and contactless measurement perfectly fit the market trend of higher power and higher isolation.

Main benefits High global accuracy (Measurement of bi-directional current up to 1500AOver Current DetectionProgrammable CAN features (CAN ID, Baudrate, Frame emission period)Output signal: high speed CAN (500 kbps)Functional safety capability up to ASIL C (according to ISO 26262-2018 Ed.2) Main features Fluxgate based measurement Automotive quality standards compliant Unipolar +12V battery power supply Full Galvanic isolation Connector type: Tyco AMP 1473672-1 Choice of range: ± 500A, ± 1500A Flexible mounting options (panel or busbar) Low power consumption, no additional cost for heat dissipation during fast charging cycle CAB 1500, your best choice for Li-ion battery management
