Pando Electric: load management that leverages existing infrastructure for EVs

Amid the rapidly advancing Electric vehicle (EV) charging sector, the focus has centered on expanding public charging for on-the-go EV drivers, overshadowing the fact that more than 90% of EV charging transpires at residences and offices. This situation poses hurdles for multi-family housing and office residents who lack the privilege of installing personal chargers, compelling them to rely on public charging. Rectifying this imbalance necessitates collaboration among developers, infrastructure providers, governments, and EV manufacturers. Solutions encompass shared charging stations, regulatory mandates for multi-family developments, and more importantly, technological innovations. The mass adoption of EV in the coming years calls for an innovative solution that can leverage existing infrastructure and utility capability to serve as many EV drivers as possible. With that mission in mind, Pando Electric becomes the pioneer in bringing the Pando Sprout Load Management System (PS-LMS) to our customers.

EV charging load management holds significant importance for locations with multiple charging stations, particularly in commercial and multi-unit contexts. Load management revolves around the careful calibration of electricity consumption to ensure it remains within the capacity of the existing infrastructure. Within commercial spaces, electricity demand varies due to factors like office occupancy or appliance use, necessitating load management through network control to maintain system stability. In the realm of EV charging, effective load management is essential to prevent exceeding prescribed thresholds.

Dynamic load management systems govern the distribution of electricity across various charging stations connected to a singular circuit. These systems can be categorized as either network-based or local in nature. Local load management involves on-site communication without reliance on external networks, potentially leading to cost reductions.

Local load management serves as a crucial mechanism for efficiently allocating power among charging stations, preventing overloading of the electrical panel. Through load sharing, each station collaborates with others to ensure an equitable distribution of electricity based on the demand. Traditionally, if an electrical panel provides 80 amps and there are four 40-amp chargers in use, each station could be assigned 20 amps to avert excessive power draw. However, serving more EVs by reducing charging current simply means higher charging overhead and lower charging efficiency. Take L1 smart outlets as an example, the overhead energy loss could be as high as 20%! At Pando Electric, we invented the smart scheduling AI-based algorithm that can actively monitor the amps usage and EV status. Our proprietary in-house system can also prioritize special charging requests while maintaining overall user satisfaction.

Dynamic load management automates the allocation of charging resources for further enhanced efficiency, bringing the game to another level. Through actively monitoring the panel and amp usage, Pando Sprout further frees up charging capacity during trough time by an order of magnitude. It helps optimizing the delivery of electricity, alleviating strain on infrastructure, and offering benefits such as cost savings and streamlined energy consumption during peak and off-peak periods. In situations involving multiple EV charging stations, PSLMS emerges as a pivotal strategy. Collaborating with certified electricians, Pando works closely with our customers to design the most suitable load management approach, considering usage patterns and future scalability.
