Definition: Transport refrigeration units powered by rechargeable batteries instead of diesel engines or direct vehicle electrical systems.
Advantages:
Zero emissions during operation (indoor loading bays, residential deliveries)
- Silent operation (noise-sensitive areas)
- Lower operating cost than diesel (if electricity cheap)
- Reduced maintenance (fewer moving parts than diesel TRU)
Disadvantages:
- Limited operating time (typically 4-12 hours per charge)
- Charging infrastructure required
- Higher initial cost
- Battery degradation over time
- Reduced capacity in extreme heat
Best Applications: Urban last-mile delivery, short-haul routes, multiple daily charging opportunities
