Real-time provider pricing
VoltEdgeSystem reads the live electricity cost from your connected energy provider API.
Battery-level-based cost rules
Each battery range can have its own user-defined cost threshold for charging decisions.
Automatic charge or pause decisions
VoltEdgeSystem compares the live price with the active battery rule and decides whether charging should continue or pause.
Price-based charging logic
VoltEdgeSystem reads live energy cost, checks the current battery level, and applies the active cost threshold before deciding whether to charge now or pause charging.
Battery-level price rules
Allow higher prices when the battery is low and lower prices when the vehicle already has enough charge.
Connect your energy provider pricing API
Add the user-provided provider API link so VoltEdgeSystem can evaluate the current electricity price continuously.
Driver control stays first
Manual override and driver control stay visible whenever the current price is above your limit or the charging decision needs review.
How VoltEdgeSystem Works
1
Connect your Tesla account
Start with Tesla sign-in so VoltEdge can read supported vehicle and charging data.
2
Add your energy provider API
Provide the pricing API link so VoltEdge can read the real-time electricity price.
3
Set battery-level price rules
Define acceptable electricity prices for each battery-level range.
4
Let VoltEdgeSystem decide
VoltEdge compares the live price with the active battery rule and applies the charge-or-pause decision.
5
Stay in control
Review the reason behind the decision and use manual override when needed.
Tesla Real-Time Charging FAQ
How does VoltEdgeSystem decide when to charge?
VoltEdgeSystem checks the real-time electricity price from your energy provider and compares it with your battery-level charging rules.
How does VoltEdgeSystem decide whether to charge?
It checks your current battery level, reads the real-time electricity price from your provider API, and compares that price with the cost limit you set for that battery range.
Can I set different prices for different battery levels?
Yes. You can allow higher charging costs when the battery is low and require lower costs when the battery already has enough charge.
What happens if the current electricity price is above my limit?
VoltEdgeSystem can pause charging until the live price falls within your acceptable range, unless your settings or manual override say otherwise.
Where does the electricity price come from?
The user provides the API link from their energy provider, and VoltEdgeSystem reads the real-time electricity cost from that source.
Can I override the charging decision?
Yes. VoltEdgeSystem supports user-defined preferences and manual override so the driver stays in control.
What happens when the battery is very low?
Users can set higher acceptable price limits for lower battery ranges, allowing VoltEdgeSystem to prioritize charging when the vehicle needs energy more urgently.
Control Tesla Charging by Real-Time Electricity Cost
Connect your Tesla, add your energy provider pricing API, set battery-level cost limits, and let VoltEdgeSystem decide when charging should continue or pause.
