Quasar stops charging at 97 percent of the battery capacity

Introduction

Wallbox continuously strives to provide its customers the best products, services, and user experience. A very important part of our impressive product line-up is Quasar. Quasar is world´s first bi-directional direct charger designed for home usage. 

Quasar not only charges EVs but can also send electricity back to the grid or even power a home. Quasar uses the vehicle- to- home technology to power your home.

Vehicle-to-Home (V2H) technology offers several benefits, including reducing home electricity bills and offering a ready source of emergency power. 

Why your Quasar stops charging at 97% of the battery capacity.

Quasar stops the charging process when the battery of your electric vehicle reaches 97% of its charging capacity.  When the vehicle’s charging session is almost complete, the charging speed begins to fall. 

The charging process automatically stops when the battery reaches 97% of its capacity.  The battery is never fully charged to 100% of its capacity. 

Wallbox has determined that to enable effective discharging of the battery it is essential that Quasar stops the charging process at 97%.  Charging above the 97% percent of the battery capacity impedes the discharging process.

Hence, to restrict the charging above 97%, the Maximum Battery Percentage control parameter is configured at 97%. The Maximum Battery Percentage control is pre-set in Configuration –> Installation Options section of mailbox, mobile application, portal, and HMI and will normally remain fixed.

While setting up a manual charging schedule using the myWallbox or the myWallbox portal, you can:

  • Set the type of schedule: charge or discharge.
  • Sets start and end time.
  • Sets desired State of Charge (SoC). The SoC can be set to any value below 97% for charging since the default value for the Maximum Battery Percentage control parameter is configured at 97% and for discharging you can set the minimum value of discharge to any value below 60% since the default value for the Minimum Battery Percentage control parameter is configured at 60% .
