01Overview

On-board chargers are devices that are installed in electric vehicles (EVs) to convert AC power from the grid to DC power to charge the vehicle's battery. These chargers typically operate at a specific voltage and power rating, and it is important to consider the derating of the charger when designing an EV charging system.

 

In the case of a 24V&36V on-board battery charger, the power rating may need to be derated based on the ambient temperature of the environment in which it is installed. For example, if the charger is designed to operate at a maximum power output of 3kW at 25°C ambient temperature, it may need to be derated to 2.4kW at 50°C ambient temperature to ensure reliable operation.

 

Additionally, Some 24V&36V full power on-board battery chargers may have advanced features such as programmable charging profiles, which allow for customized charging settings based on the specific needs of the battery system. This can help optimize charging efficiency and prolong the life of the battery.

 

It is also important to note that some 24V&36V full power on-board battery chargers may require professional installation to ensure proper functioning and safety. It is recommended to consult with a qualified electrician or technician before installing or using any battery charging equipment.

 

Overall, a 24V&36V full power on-board battery charger is a crucial component for maintaining the performance and longevity of high-capacity battery systems in various applications. Choosing the right charger with the appropriate features and specifications can help ensure optimal charging efficiency and safety.

07FAQ

Do you also do OEM or ODM products for customers? 

Yes, we could do OEM and ODM services for our customers around the world. You could forward your details demands to us via email, WhatsApp, or WeChat. 

 

What color do you have for your battery chargers?

We have silvery color which customers ordered most, and Blue, Red, Black, or other colors can be produced as per your request as well. Please kindly provide the Pantone colors you need, then we will check and confirm for you immediately.

 

How do you make it to meet IP65 waterproof?

We do full glue inside the charger, and the LED’s to be glued from the inside properly. Put the rubber gasket between the edges of the side plates and the metal case. Put epoxy glue on all external open screws. The fan outside also has IP65 waterproof certificate.

 

Did the charger has an interlock function?

If the charger is On board charger model, it has the interlock function. When the batteries are being charged (charger is being used with AC on), the electric vehicle motor, headlight, etc. cannot be used and the electric vehicle cannot move too. It is done by using the signal from the interlock.

 

If your battery charger can work for both lead acid and lithium batteries at the same time?

A battery charger can work for 1 type of battery after the factory setting. If you have both lead acid and lithium batteries, we’d like to suggest taking both lead-acid chargers and lithium chargers. Please contact our expert to advise your battery type and voltage, then we will provide the suitable one for you very soon.

 

Why can't lead-acid batteries and lithium batteries of the same voltage use the same kind of charger, such as 57.6V lead-acid batteries and 57.6V ternary lithium batteries sharing a charger

Specifically, when the charger charges a 57.6V lithium battery, and reaches the constant voltage stage of 57.6V and the current reaches 2A, the charger cut off automatically; When the charger charges a 57.6V lead-acid battery and reaches the constant voltage stage of 57.6V and the current reaches 5A, the charger switches to the float charge stage of 55.2V. If use the charger which designed for lithium batteries to charge lead acid batteries , this way will reduce the life of lead acid batteries due to the lack of floating charging 55.2v; If use the charger which designed for lead acid batteries to charge lithium batteries , this way will cause the lithium battery to not be fully charged due to the process of floating charging 55.2v. Therefore, we recommend that lead-acid batteries and lithium batteries be charged by their specially designed chargers respectively.

 

Could you explain the Precharge function? 

 Precharging is to protect the life of the battery. When the battery voltage is lower, the internal resistance of the battery is greater (the heat is more serious), and the current it can withstand is smaller. Precharging is to reduce the current when the battery voltage is low to reduce heat generation to protect the battery.

 

How many colors does the LED light(Indicator) come with? And what is the meaning of each color?

We have the LED indicator with tri colors, yellow, red and green color.

Steady Red Indicator:Charging

Steady Yellow Indicator:Almost Full

Steady Green Indicator:Full

Red Indicator Flashing:Charger failure 

1. Initially just powered on - 1S period flashes

2. The battery is reversed - 0.5S cycle flashes

3.  Output overcurrent -1S period flickering

4.  High battery voltage - 2S period flashing

5.  Low battery voltage - 3S period flashing

6.  Output voltage high - 4S period flashes

7.  Battery failure -5S period flashes

 

What is the operating & storage temperature range for this charger?

The operating temperature -20℃ ~ 50℃, storage temperature -40℃ ~ 80℃.

 

Can you make with universal input voltage 100 – 240Vac if required?

Yes, our chargers support 100-240VAC and 50/60Hz. No matter your market is European, South American, Asia or others, we are all supported.
