Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If indirect heating devices (heating film or liquid device) are used inside or outside the battery pack, then the battery pack can be heated, but the heating power is low, heating time is long, and heating efficiency is low
Solution Approach 1:
The battery pack uses its own internal energy storage capacity to generate heat through controlled charging and discharging cycles. The battery pack serves itself as both the energy source and the heating target, eliminating the need for external heating devices. This self-service approach enables high-power heating with fast response time and high efficiency.
2Temperature
If built-in indirect heating devices are used, then one vehicle can be heated, but only a single vehicle can be heated at a time
Solution Approach 1:
The portable energy storage device is designed with multiple output terminals that can simultaneously connect to multiple battery packs. The device can distribute energy to several battery packs at the same time, enabling parallel heating of multiple vehicles. This multi-functionality transforms the system from single-vehicle heating to multi-vehicle simultaneous heating capability.
3Temperature
If external energy sources (lead acid battery or AC commercial electricity) are used for heating, then additional energy sources are required, but this increases device complexity and energy consumption
Solution Approach 1:
The battery pack utilizes its own stored energy to generate heat through internal electrochemical reactions during charging and discharging cycles. This self-service mechanism eliminates the need for external energy sources such as lead acid batteries or AC power supplies, thereby reducing device complexity and avoiding additional energy consumption from external sources.
4Temperature
If indirect heating methods are used, then heating can be achieved, but heating efficiency is low
Solution Approach 1:
The battery pack directly converts its stored energy into heat through internal electrochemical processes during controlled charging and discharging. This direct energy conversion within the battery pack eliminates energy losses associated with indirect heating methods, such as heat transfer through heating films or liquids, thereby achieving high heating efficiency.
