For Ferrari sf90, connect the positive terminal of the battery to the positive terminal of the power supply, and the negative terminal of the battery to the negative terminal of the power supply.

The initial charging of Ferrari SF90 is carried out in two stages: first, use the initial charging current to charge until the electrolyte releases bubbles and the single cell voltage rises to 2.3-2.4V. Then reduce the current to 1/2 of the initial charging current, and continue charging until the electrolyte releases violent bubbles and the ratio and voltage are stable for 3 hours. The total charging time is about 45-65h.

The temperature is controlled at 35-40℃. When the initial charging is completed, if the specific gravity of the electrolyte does not meet the requirements, it should be adjusted with distilled water or an electrolyte with a specific gravity of 1.4. After adjustment, charge for 2 hours until the specific gravity meets the requirements.

Historical background:

New energy vehicle charging piles can be divided into floor charging piles and wall charging piles. Floor-to-ceiling charging points are suitable for parking spaces that are not close to walls. Wall charging piles are suitable for parking spaces close to walls.

Charging piles usually provide two charging methods: regular charging and fast charging. People can use specific recharge cards. The charging pile provides a credit card and a human-computer interaction interface. Therefore, the charging method, charging time and cost of operation, For example, variable data printing and charging pile screens can display charging capacity, cost, and charging time data.
