Electric cars still face a big hurdle: the charging system

"For customers who lack experience with EVs, this patchwork network can bring frustration. EV owners are required to sign up for multiple services, each with its own access card or app. Maintenance can be hit or miss, and the last thing an EV driver running out of juice wants to do is pull into a charging stall and find it out of service."

They are companies that run most charging stations in the US.

Spark is different

Instead of giving users full charge. Spark provides short-time-charging which gives users longer range until they find a charging station to fully charge their cars.



1. Add cars to user profile (Keep car in user’s profile to keep track of car’s range).

2. Order charge (SPARK will be able to locate user’s car and bring charging to the car).

3. Select charging quality & length (Two different price tiers for two different charging strength. The one with higher price adds more range than the other).

4. Charging progress update (User can see duration of each charge as well as his/her car’s current range).

5. Rating for each charge (For SPARK to improve future experience).
