Hybrid EV Charging and Crypto Mining Under Shared Power Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional EV charging infrastructure generates revenue only when actively charging EVs, resulting in significant idle time and inefficiency, while cryptocurrency mining consumes high energy and generates heat that is often wasted, lacking a unified solution for simultaneous revenue generation and energy utilization.
Innovation Solution
A hybrid apparatus combining an electric vehicle charger and a cryptocurrency miner, managed by a power coordinator, which adjusts mining intensity to align with available power within the rated maximum capacity, ensuring continuous cryptocurrency mining and EV charging without exceeding power limits, and utilizing heat generated for building heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cryptocurrency mining operates at maximum power draw, then mining productivity increases, but power consumption exceeds available capacity when EV charging is needed
Solution Approach 1:
The system dynamically adjusts mining computer intensity levels based on real-time power availability. The power coordinator continuously monitors EV charging power draw and adjusts mining intensity accordingly, transitioning from static maximum power operation to dynamic adaptive power management that optimizes both mining productivity and power consumption.
Solution Approach 2:
The system changes operational parameters by adjusting the intensity levels of mining computers. Instead of operating at fixed maximum capacity, the mining system varies its power consumption parameters to match available power capacity, enabling flexible adaptation between full mining operation and EV charging support.
2Speed
If EV charger operates at maximum power draw, then charging speed increases, but mining power availability decreases
Solution Approach 1:
The system implements partial action by allocating a portion of total power capacity to EV charging while reserving remaining capacity for mining operations. Instead of dedicating 100% of power to charging, the system divides power distribution to maintain both charging functionality and continued mining productivity.
Solution Approach 2:
The power coordinator enables the electrical system to serve multiple functions simultaneously - EV charging and cryptocurrency mining. The system universally manages power allocation between these two competing demands, allowing the infrastructure to fulfill both transportation energy needs and digital asset generation.
3Productivity
If mining computers operate at high intensity, then cryptocurrency generation increases, but heat generation becomes waste that requires cooling infrastructure
Solution Approach 1:
The system converts the harmful waste heat from mining operations into a beneficial resource for building heating. Instead of requiring active cooling infrastructure to remove excess heat, the system utilizes the generated thermal energy to heat buildings, transforming an energy loss into a useful output that reduces overall energy consumption.
Solution Approach 2:
The mining operation serves dual purposes: generating cryptocurrency and providing heating services. The heat generated by mining computers automatically benefits the building without requiring separate heating infrastructure, enabling the system to self-service both computational and thermal needs.
4Ease of manufacture
If hybrid apparatus shares rated maximum power capacity between EV charger and miner, then infrastructure cost efficiency increases, but power coordination complexity increases
Solution Approach 1:
The power coordinator implements continuous feedback monitoring of power consumption by both EV charger and mining computers. By real-time measurement and adjustment based on actual power draw, the system manages the complexity of shared power allocation dynamically rather than requiring complex pre-planning, simplifying infrastructure design while maintaining efficient power coordination.

AI summary
A hybrid apparatus for charging electric vehicles and mining cryptocurrency is provided. The apparatus may comprise an electric power input associated with a rated maximum power capacity, an electric vehicle charger, a cryptocurrency miner and a power coordinator. The electric vehicle charger may have at least one vehicle power outlet and a maximum charger power draw from the electric power input. The cryptocurrency miner may have multiple cryptocurrency mining computers and a maximum miner power draw from the electric power input. Each mining computer may have an adjustable intensity level. The power coordinator may be configured to determine mining power availability within the rated maximum power capacity after prioritizing power demand by the electric vehicle charger, and to direct the cryptocurrency miner to continue mining cryptocurrency by adjusting the intensity levels of the mining computers such that the cryptocurrency miner consumes not more than the mining power availability.
