Lead Power Electronics Engineer - Battery Management Systems
Our innovative technology client is seeking a Lead Power Electronics Engineer - BMS to join their research team to be a part of concept development of new products within the business.
The Lead Power Electronics – BMS role will involve:
The development of battery management systems and assessment of alternative battery management solutions and topologies depending on the product requirements
Ensuring battery management systems meet regulatory and company requirements for safety
Charger design and writing detailed charger specifications
Power Converter Design.
Ensuring designs can comply with relevant EMC/EMI standards and modifying design where needed to ensure this is the case.
Thermal management design of power electronics systems
Design of both mains and battery powered electronics to meet global requirements.
Working with different product teams to gain an in depth product understanding, while using knowledge of the latest technologies to create innovative power electronics systems and solutions.
Research into new technology and investigating ways of incorporating this technology into future products.
Use of simulation and PCB design software to create prototypes.
Strong lab skills to build and test prototypes with minimal supervision.
As a Lead Engineer, the successful applicant will be expected to:
Develop the concept, proving key technologies and demonstrating the system feasibility
Produce clear, well written documentation prior to handover to the development teams
Take technical responsibility for the battery management system and associated power electronics content of a project. This may expand to the responsibility for multiple small concurrent projects, supported by a number of team members.
Demonstrate designs are safe, robust, cost effective and fit for purpose for a high volume manufacture environment, through detailed laboratory testing, simulation and analysis
Assist in the personal development of junior team members.
Education and experience:
Minimum BEng/MEng degree in Electrical & Electronic Engineering or other relevant discipline
Minimum technical knowledge:
Experience in the design of Battery Management Systems especially for Lithium-Ion technology.
Experience in motor inverter design and motor control, particularly brushless DC motors, servo or stepper motors desirable.
Knowledge of heater control hardware, control schemes and heater protection approaches desirable
General knowledge of power electronic devices, including silicon based IGBTs, MOSFETs and wide bandgap technologies
Understanding of device characteristics and issues with switching behaviour in real circuits, as well as power switch driver design
Device selection - Interpretation of datasheets and knowledge of design methods to confidently select the lowest cost devices while achieving reliability targets
Knowledge and experience of using power hybrid modules and power SoC modules (e.g. drivers and power switches in one device)
Thermal management approaches for surface mount and through hole devices
SMPS and linear regulator power supply design
Design of power electronics for both low voltage and mains voltage systems
Control circuit design:
Understanding of techniques for accurately monitoring small signals in high power, electrically noisy environments.
Excellent knowledge of analogue signal conditioning (e.g. op-amp circuit design) and ideally digital signal processing approaches
