Nucular electronics — the platform for design light electric vehicles (LEV)

A unified control system for electric vehicles, such as electric bike, motorbike, scooter, golf car. All components are synchronized with each other in order to effectively and smoothly control electric vehicles.

Electronics kit

All devices are connected by CAN-bus. Each component can be used separately with devices from other manufacturers.
Controller
For controlling a permanent magnet motor
(BLDC).
On-board computer
To display the basic parameters, set the modes of motion and control.
Battery Management System
Battery Management System (BMS) is a system for controlling the energy consumption of a battery.

Components overview
We offer components for self-assembly of light electric vehicles. If you are an electric vehicles
development company, we can become your OEM partner, which will save a lot of time and
effort, thanks to a reduction in the cost of research, development, testing and support of your
own components. Using our line of solutions you get constant technical support and software updates.

A powerful ARM microprocessor provides precise and smooth control of the BLDC motor. The controller settings are widely configured - you can set parameters, power strokes of the gas handle, fully customized to your needs. The controller achieves an efficiency of 99% due to the powerful MOS transistors and special PWM algorithms. Compact size allows you to install it in any suitable place on vehicles with different dimensions — from scooters to ATVs or golf carts.

Battery Management System (BMS) 16S | 24S
Battery Management System is a system for controlling the energy consumption of a battery. BMS protects each element in the batteries from discharging and recharging. An adaptive battery balancing algorithm accelerates the time of voltage equalization between its elements. For cold weather, the BMS provides for heating the battery. The wattmeter calculates how much energy was used and shows the statistics of energy consumption. The user is able to see the state of charge of the battery and the error diagnosis on the information screen.

In developing. Pre-order available.

Why Nucular?
In English "Nucular" is a commonly used mispronunciation of the word "nuclear". We used this word to emphasize high power density of our controllers
