3.5kW Portable AC EV Charger

Choose AC or DC by dwell time
AC charging generally suits homes, apartments, hotels, workplaces and other locations where vehicles remain parked longer. DC charging is evaluated for fleets, fuel stations, taxi operations, public charging and short-stop sites. The correct choice depends on daily energy demand, parking duration, vehicle capability, turnover, grid capacity and investment plan. Many networks use both types for different user journeys.
Build the site scenario
Define who will charge, how many vehicles arrive, when demand peaks, how long vehicles stay and whether access is private, semi-public or public. Include parking layout, traffic flow, accessibility, expansion space and operating responsibility. This scenario determines the number of charge points, power allocation, authentication, payment and service model more reliably than a simple charger-count target.
Confirm the destination-market interface
Connector standards, cable arrangements, vehicle compatibility, payment methods and installation requirements vary across Ethiopia and Southeast Asian markets. State the country, vehicle mix and preferred interface at the start. Do not assume that one global configuration is appropriate. The selected model, connector, metering and payment solution must be checked against local project and approval requirements.
Plan software and operations
The project brief should define user authentication, CSMS, OCPP version, tariffs, payment, networking, remote monitoring, fault handling, reporting and OTA policy. These functions may vary by model and firmware. Distributors and operators should request a feature matrix and interoperability evidence rather than relying on broad “smart charger” language.
Size the electrical infrastructure
Review the utility connection, transformer, switchgear, cables, earthing, protection, peak demand and future chargers. Large DC sites may need a dedicated transformer or staged capacity plan; AC sites may benefit from load balancing. Where the grid is constrained, the project engineer can study demand control or storage, but such functions should not be promised until the system design and compatible equipment are confirmed.
Define installation and service scope
Clarify who is responsible for design, permits, civil work, electrical installation, commissioning, network setup, training, warranty, spare parts and ongoing support. Provide the country and site schedule so the commercial response can distinguish equipment supply from optional services. Any local approvals or certifications must be confirmed for the selected model and project.
Submit an EV charging project brief
Send the country, site type, vehicle mix, parking time, sessions per day, AC/DC preference, power supply, connector, authentication, OCPP/CSMS, payment, networking, environment, quantity, installation responsibility and target schedule. LONTEN can then route the enquiry to AC or DC model review and identify missing inputs.
