The main application of LEM in automotive battery management

The automotive division of LEM electronics focuses on the development and production of battery management and motor-driven current sensors for cars, buses and trucks. By controlling the current of high energy consumption applications, LEM is playing its own role in global efforts to reduce energy consumption. Typical applications of LEM automotive sensors include:

Standard battery monitoring

Current measurement of hybrid and electric batteries

Fuel cell current control

DC / DC converter and AC / DC inverter

Inverter drive for hybrid and electric vehicles

EPS and wire control application

Electric compressor of air conditioner

The main applications of LEM automotive battery management are as follows:

Traditional battery management for several years, vehicle manufacturers focus on reducing fuel consumption. At present, the main focus is to reduce fuel consumption by managing the charging process of the main battery. The focus of energy management in the early stage of power transformation is particularly on the process of energy management. A combination of additional functions including battery management, battery life and safety feature status, such as automatic power off. Auxiliary function reduction and alternator size optimization have directly reduced the overall electrical loss. Hall effect sensors (HAB, habt, hag, HAH1) and intelligent shunt (ssvt) are optional products for this application.

The demand for high energy in the generator current monitoring vehicle is growing. The generator needs to provide more current to the vehicle load and battery. In order to achieve high efficiency, the current needs to be controlled. HAB and hag current sensors are the best product family to provide suitable current information for BMS (battery monitoring system). Depending on the size of the car body, the current flows from 60A (traditional vehicles) to 240A (service vehicles and trucks).

Battery management in the hybrid and electric vehicle market. Both of them need high current capacity batteries to run more than 50KW motors and need high voltage system. The current sensors used in these batteries require insulation. Fluxgate sensors (CAB) and Hall effect sensors (HAH1, HSN, Dhab) are candidates for this application.
