Punjab PSEB Matric NSQF Automotive (EV Service Assistant) · Work through your exam, one topic at a time.
The Punjab School Education Board (PSEB) Matric NSQF Automotive (EV Service Assistant) is a Class 10 vocational qualification under the National Skills Qualifications Framework, delivered through PSEB-affiliated schools offering the automotive sector strand. It suits students who want a school-leaving credential plus entry-level, job-ready skills in electric vehicle servicing rather than a purely academic route. The Punjab PSEB Matric NSQF Automotive (EV Service Assistant) study guide has 10 sections and about 3,079 words.
01Introduction to the Automotive Sector and EV Ecosystem
The exam checks whether you can place an EV workshop inside the wider automotive sector. You need to name vehicle types, identify EV subsystems and explain how industry, policy and services connect.
332 words, about 2 min02Electrical and Electronics Fundamentals for EVs
This domain tests basic electricity as it appears on an EV: voltage, current, resistance, power, DC and AC, series and parallel circuits, and the meters and components used to test them. Ohm's law: V = I × R.
334 words, about 2 min03Battery Technology and Battery Management Systems
Questions focus on lithium-ion cells, pack construction, the meaning of SoC and SoH, and the BMS functions that keep the pack safe and long-lived. Cell to pack: cells form modules, modules form the pack.
306 words, about 2 min04Electric Motor, Controller and Drivetrain
This domain checks your understanding of the traction motor, the controller/inverter, position sensors and the reducer, plus torque, speed and regenerative braking. Motor types: PMSM and BLDC use permanent magnets and are common in EVs; induction motors have no magnets; switched reluctance motors are robust.
327 words, about 2 min05EV Charging Infrastructure and Charging Procedures
You must know AC and DC charging, connector types, the handshake between vehicle and charger, charging limits and the safety checks before and after a charge. AC charging: the onboard charger converts AC to DC.
309 words, about 2 min06EV Maintenance, Diagnosis and Troubleshooting
This domain tests scheduled maintenance, fault diagnosis and repair logic for EVs, including the 12 V system, HV insulation, DTCs and road-test checks. EV maintenance: no engine oil or spark plugs; check battery coolant, brake fluid, tyres, suspension, steering, HV connectors, seals, cabin filter and software updates.
304 words, about 2 min07High-Voltage Safety, PPE and Emergency Response
High-voltage safety is a pass/fail area: hazard recognition, PPE, lockout/tagout, verification of de-energisation and emergency response. HV threshold: treat systems above 60 V DC or 30 V AC as hazardous; EV packs are commonly 300–800 V.
309 words, about 2 min08Workshop Practice, Tools, Documentation and Customer Interaction
This domain tests workshop discipline, correct tool use, job documentation and professional customer handling in an EV workshop. 5S: sort, set in order, shine, standardise, sustain; keep HV tools separate and inspected.
298 words, about 1 min09Employability Skills
Employability skills are assessed through communication, teamwork, safety behaviour, digital tasks, interview readiness and career planning for an EV workshop role. Communication: listen, confirm understanding, use simple language, report faults accurately and escalate when unsure.
285 words, about 1 min10Entrepreneurship and Environmental Awareness
This domain links EV service work to self-employment, small-business planning, environmental rules and the circular economy for batteries. Business basics: identify a service gap, estimate demand, price labour and parts, control stock, track cash flow and keep records.
