Within the automotive market, there are reams of applications. EBV presents some of the most exciting application examples in the fields of:



New market for clever electronic solutions

Hybrid electric vehicles (HEV) and fully electrically driven vehicles (EV) each require sophisticated electronics. As well as for control of the traction motor, the battery above all requires a separate control unit. The system known as BMS (Battery Management System) constantly detects the present state of charge of each individual cell and uses cell balancing to equalise the charge between the cells as required, monitoring the whole battery and ensuring the safety of this energy storage device. Because a constantly running internal combustion engine is no longer available in (H)EVs, all the auxiliary equipment such as the air conditioning or power steering must be driven electrically.


Less pollution with the Stop/Start system

Stop/start systems switch off the engine during waiting times at traffic lights, etc., – but only if certain general conditions are met. To do this, the control unit of the stop/start system must evaluate information from various sensors and then control the engine and starter motor accordingly.

Battery management

The centrepiece of every traction battery

The battery management system (BMS) is the centrepiece of every traction battery because it is responsible for both the safety and also the availability and longevity of the battery. In addition it controls the air conditioning of the battery so that it is always kept in an optimum and safe operating state. The BMS must be highly available and must never fail, so that a thermal runaway (burning) of the battery and the associated dangerous situation are prevented under all circumstances.

Motor control

High reduction of energy consumption

The energy consumption in vehicles with internal combustion engines can be reduced by the electrification of accessories. Dedicated motor control units are required to control each of the electric motors in these accessories, as well for the control of other actuators. The spectrum here ranges from microcontrollers with integrated PWM controllers to complex motor control ICs with integrated drivers.


Power steering - highly safety relevant system

In electric power steering (EPS) and electro-hydraulic power steering (EHPS), sensors and especially-safe microcontrollers are also necessary in addition to motor controls, because power steering counts as one of the highly safety-relevant systems in the vehicle and must meet the requirements of the ISO 26262 standard.


Autogas as an effective alternative for petrol and diesel

Vehicles that are driven by an internal combustion engine need not necessarily contain a diesel or petrol engine. Operation using autogas is also possible, whereby either CNG (Compressed Natural Gas) or LPG (Liquefied Petroleum Gas, propane/butane) is used as the fuel in most cases.
