You have charged your battery and there is an indicated display “fully charged.” You start riding confidently, but out of nowhere, the battery suddenly loses its power and leaves you clueless in the middle of the road. That happens when you do not consider a quality charger with your lithium battery.
Many riders focus only on the features of the battery and pay less attention to the charger. Sometimes they choose an ordinary charger instead of a smart one. A smart charger continuously monitors the charging current and temperature throughout the charging process.
According to the Stats of BESS, there is approximately 1.25 GWH of Battery Energy Storage Systems (BESS) developed in 2024. This is because of the rapid growth in lithium battery adoption for electric vehicles in Pakistan.
Saas Smart Chargers are the trusted smart charging solutions available in the Pakistani market. Their intelligent system supports battery health and optimizes charging performance.
In this blog, we will explore what a Saas Smart Charger is, how it works and the different types available for electric bikes.
What is a Saas Smart Charger?
A Saas Smart Charger is designed to charge lithium batteries through an intelligent charging process. It works along with the Battery Management System (BMS) to monitor voltage and temperature throughout each charging cycle. By automatically adjusting the charging process at every stage, it helps protect your battery from overloading and keep a good balance between the cells.
Saas Smart Chargers are available in 3A and 5A types. They are specially designed for lithium battery systems and have various features. Its intelligent charging, voltage regulation and temperature sensors can automatically cut off. They help you deliver uninterrupted and charging to electric bikes and scooters.
How Does a Sass Smart Charger Work with Its Smart Features?
-
Battery Detection
When you connect the battery, the SASS Smart Charger automatically detects the voltage of the battery and charging requirements. The charger delivers the required charging for safe and fast performance.
-
Intelligent Multi-Stage Charging
The charger has a multi-stage charging map that includes Pre-Charge, Constant Current or Float Charge Completion. It adjusts the charging current and voltage at each phase smoothly. This leads to more capacity and improves battery performance, along with extending battery lifespan.
-
Continuous Monitoring
The charger continuously monitors your battery parameters such as voltage and temperature. If any unstructured charging condition is detected, it automatically adjusts the charging output to safe operating conditions. This operation protects the battery from overheating and further short circuits.
-
Automatic Cut-Off
Sass smart charger automatically detects your battery when it reaches full optimized charge. When it is full, it immediately stops the charger from drawing current to safe mode. This function helps it to prevent overcharging and reduces excess heat generation while protecting the battery cells and Battery Management System (BMS). It helps you extend the lifespan of the battery and deliver reliable charging.
-
Reverse Polarity Protection
If the battery terminals are not connected correctly, the reverse polarity protection system in the battery immediately blocks the flow of current. This process helps prevent damage to the charger's internal parts and protects the battery from electrical faults while safeguarding the entire charging process.
-
Durable ABS Housing
The charger is sealed in a durable ABS housing that helps prevent overheating and protects it from minor impacts during daily use. It also reduces wear caused by regular handling and movement with plugging in and unplugging. The strong outer casing keeps the internal electronic components safe from external damage with stable performance.
