How many watts does a small car lithium battery charger typically have?

Introduction Lithium battery cars typically have a few watts of chargers. Electric cars with 48V batteries are equipped with chargers (usually switching power supplies) to accommodate batteries of different capacities (usually 14A to 14A).

How many watts does a small car lithium battery charger typically have?

The charger for an electric vehicle with a 48V battery (usually a switching power supply) is designed to accommodate batteries of different capacities (usually between 14 amp hours and 20 amp hours). the charging current is set to 1.8A, the electric power at this time is about 110W.

Different models of electric vehicle chargers have different power ratings, usually 220 W. When charging the electric vehicle charger, plug in the battery first, then add AC power; when sufficient, first turn off the mains power and then disconnect the battery. If you first disconnect the battery when charging, especially when the charging current is large (red light), it is very easy to damage the charger.

Commonly used switching power supply chargers are divided into two categories: half-bridge type and half-bridge typesingle excitation. The single excitation type is further divided into two categories: forward type and flyback type. The half-bridge type has high cost and good performance, and is often used in negative pulse chargers; single excitation type has low cost and high market share.

The most common car battery chargers are 120W (48V 10~14Ah) and 180W (48V 17~22Ah). The electric vehicle charger with 48V battery is suitable for batteries of different capacities (generally between 14 Ampere hours and 20 Ampere hours). The first stage charging current is set at 1.8 Ampere, and the electrical power at this time is approximately 110 W). .

In the second stage (when charging to nearly 90% capacity), the charging current is about 0.5-1A and the electric power is about 60W at that time until it is fully charged, the power; the consumptionis around 10W when it goes into trickle charging. As for the time required for a single charge, it is linked to the degree of discharge of the battery and its condition. It takes approximately 8 hours for a new 14Ah battery to be fully charged after being completely discharged.

The most durable and cheapest electric bike

Lithium batteries and lead acid batteries are currently commonly used battery types for electric bikes. electric bikes. They each have their own type of battery. advantages and disadvantages. Which one is better depends on the user's needs.

Advantages of lithium batteries: Lithium batteries have smaller size, lighter weight, higher energy density, longer life, higher performance, higher security and better usability. Lithium batteries can use fewer battery packsies, smaller size, lower cost, less maintenance, higher reliability and higher feasibility.

Advantages of lead acid batteries: 1. Lead acid batteries are relatively cheap, inexpensive and much cheaper than lithium batteries. 2. Lead-acid batteries have good thermal stability and can withstand temperature changes and maintain good performance even at high temperatures.

I think the most durable and cheapest electric cars are:

1. Tailing TDT19Z

Reference price: 2,299 yuan

< p>It is suitable for young people to travel, whether it is a transportation for students or office workers.

2. Emma Chunsheng
