Five practical advantages for e-mobility battery programs

Battery architecture is matched to the vehicle package, the energy requirement, and the charging behaviour before production starts.

01

Energy planning

Size the pack against the real duty cycle instead of a brochure range.

02

Charging fit

Tune the charge window for home, depot, or public fast charging.

03

Thermal headroom

Keep performance steady under repeated load and higher ambient temperatures.

04

Pack flexibility

Carry a validated engineering base across vehicle classes instead of restarting the design.

05

Service access

Keep modules, wiring, and diagnostics reachable for maintenance teams.

E-Mobility applications

Five e-mobility battery applications

Each application is developed around its own vehicle platform, energy requirement, power delivery, packaging, and charging behaviour.

Passenger EV battery packs built around range, charging, and integration

Passenger EV battery packs start from the energy the vehicle actually needs: everyday and highway range, the charge window the driver can live with, and the pack volume the platform can give up.

Cell chemistry, module layout, and cooling are selected together, so range, mass, and the underfloor package stay in balance instead of being solved one at a time.

Pack-level BMS and diagnostics
  • Range target and energy planning
  • 400V and 800V architectures, where required
  • Thermal design matched to the charge profile
  • Vehicle integration and service access

How the pack is scoped

Range target, charge window, and pack envelope are agreed before cell format and cooling are locked, so the pack follows the vehicle package.

SUV and crossover battery packs with thermal headroom and underfloor packaging

Larger passenger vehicles ask for more energy at the same time as more cabin space, more mass, and a higher continuous load on the pack.

The pack is sized around vehicle mass and range target, then laid out for an underfloor envelope with the cooling path and enclosure structure planned from the first layout.

Higher energy Range against vehicle mass
Underfloor Packaging envelope
Thermal headroom Sustained highway load
Structure Enclosure and mounting
  • Energy sizing around mass and range target
  • Underfloor packaging and enclosure layout
  • Thermal headroom for sustained load
  • Charging behaviour matched to the platform

SUV / crossover logic

Energy, mass, and thermal headroom are traded off explicitly rather than optimised separately.

Hybrid vehicle battery packs for compact power assist

Hybrid programs need a pack that is small, light, and quick to respond. Electric assist has to feel natural without adding unnecessary mass or taking space the platform does not have.

Because the pack cycles far more often than a full battery-electric pack, charge and discharge behaviour, packaging constraints, and the control strategy are agreed with the drivetrain team from the start.

Compact Footprint in the platform
Power assist Burst power delivery
Repeated cycling Charge and discharge behaviour
Control Drivetrain integration
  • Small-footprint pack formats
  • Power delivery sized for assist
  • Cycling behaviour matched to the hybrid strategy
  • Limits agreed with the drivetrain team

Integration first

The pack is kept small and responsive so electric support is useful without forcing the rest of the platform to change shape.

Commercial EV battery packs sized from the duty cycle

Commercial packs are sized from the work the vehicle does: route length, payload, operating hours, and where the vehicle can charge during the day.

Fleet operation also shapes the design. Service access, maintenance planning, and how the pack behaves across a long working life matter as much as installed energy.

Duty cycle Sizing basis
Route-based Energy per shift
Payload-aware Mass budget
Serviceable Fleet maintenance
  • Battery sizing from route and duty cycle data
  • Payload, mass, and operating-hour planning
  • Charging access and turnaround review
  • Service access for fleet operation

Sizing logic

Installed energy follows the real operating profile rather than a fixed capacity taken from a similar vehicle.

Two- and three-wheeler battery packs built to the frame and controller

On electric motorcycles, scooters, and three-wheelers, the pack is limited by the vehicle long before it is limited by cell technology. Dimensions, weight, and mounting decide the design.

Current delivery is matched to the controller, and the BMS, connector, and charging interface are specified with the vehicle wiring in mind, so the pack arrives ready for OEM or ODM assembly.

What drives the design

Dimensions, weight, current delivery, and the connector interface decide the pack more than headline energy does.

Battery technology

Battery technology for e-mobility programs

Cell chemistry, voltage architecture, pack design, thermal management, and controls are decided together for each vehicle program.

01

Cell chemistry

LFP and NMC are both available. The choice follows the program's energy, cost, cycle, and safety priorities rather than a default.

02

Voltage architecture

Pack voltage is arranged around the vehicle architecture, including 400V and 800V systems where the platform calls for it.

03

Battery pack

Cell configuration, module or pack architecture, enclosure, cooling, BMS, connector, and service access are developed as one assembly.

04

Thermal management

Thermal behaviour depends on chemistry, power profile, operating environment, and vehicle architecture, so the cooling path is designed per project.

05

Controls and BMS

BMS functions cover cell monitoring, protection limits, balancing, and communication with the vehicle controller.

OEM / ODM development

OEM / ODM battery development process

A structured path from requirement definition to production, with the level of engineering support agreed per project.

01

Requirement analysis

Vehicle type, duty cycle, energy target, package limits, and charging expectations are reviewed together.

02

Cell and chemistry selection

Cell format and chemistry are selected against energy, power, cycle life, and cost requirements.

03

Battery architecture

Series and parallel configuration, voltage class, and module or pack structure are defined.

04

Pack design

Enclosure, cooling, busbars, BMS, connector, and service access are developed as one assembly.

05

Prototype

A functional prototype is built for bench testing and vehicle-level evaluation.

06

Testing and validation

Performance, thermal, safety, and durability checks are carried out against the agreed specification.

07

Production

Validated designs move into production with the inspection plan agreed during development.

FAQ

Questions teams ask before an e-mobility battery program starts

The answers point to the next engineering decision without overpromising.

Which chemistry fits my vehicle program?
LFP and NMC serve different priorities. LFP is usually chosen where cycle life, thermal stability, and cost per kWh matter most; NMC where the program needs more energy per kilogram and a lighter pack. The choice is made against the energy target, duty cycle, and charging profile of the program.
Can the battery pack be designed around an existing vehicle envelope?
Yes. Development can start from an existing battery envelope, mounting points, or technical specification, then move to the cell configuration and pack layout that fit that space.
Can you support different voltage architectures?
Voltage class is set by the vehicle program. The pack architecture is arranged around the required voltage, including 400V and 800V systems where the platform calls for them.
How do you size a battery for a commercial EV?
Sizing starts from the work the vehicle does: route length, payload, operating hours, and where it can charge. Energy and power are planned against that duty cycle rather than a fixed capacity.
What matters most for 2- and 3-wheeler battery design?
Dimensions, weight, current delivery, and the connector interface usually decide the design. BMS functions, charging behaviour, and service access follow from those constraints.
How do you handle thermal management?
Thermal design follows the chemistry, power profile, operating environment, and vehicle architecture. Cooling method and control strategy are set per project rather than applied as a fixed formula.
What validation data can you provide?
Validation documents depend on the program. The typical package covers the performance, thermal, safety, and durability checks agreed in the project specification.
Can you customize the battery pack for OEM / ODM projects?
Yes. OEM and ODM projects can start from a customer specification or from a joint definition of requirements. Cell selection, pack architecture, BMS, enclosure, and connector are open to project-specific configuration.
